Update RELEASES.md for 1.44.0
2020-05-09 08:13:02 +08:00
Version 1.44.0 (2020-06-04)
==========================
Language
--------
- [You can now use `async/.await` with `#[no_std]` enabled.][69033]
- [Added the `unused_braces` lint.][70081]
**Syntax-only changes**
- [Expansion-driven outline module parsing][69838]
These are still rejected semantically, so you will likely receive an error but
these changes can be seen and parsed by macros and conditional compilation.
Compiler
--------
- [Rustc now respects the `-C codegen-units` flag in incremental mode.][70156]
Update RELEASES.md Co-authored-by: Jonas Schievink <jonasschievink@gmail.com>
2020-05-09 22:30:00 +08:00
Additionally when in incremental mode rustc defaults to 256 codegen units.
Update RELEASES.md for 1.44.0
2020-05-09 08:13:02 +08:00
- [Refactored `catch_unwind`, to have zero-cost unless unwinding is enabled and
a panic is thrown.][67502]
Update RELEASES.md
2020-05-29 17:36:50 +08:00
- [Added tier 3\* support for the `aarch64-unknown-none` and
`aarch64-unknown-none-softfloat` targets.][68334]
- [Added tier 3 support for `arm64-apple-tvos` and
`x86_64-apple-tvos` targets.][68191]
Update RELEASES.md for 1.44.0
2020-05-09 08:13:02 +08:00
Libraries
---------
- [Special cased `vec![]` to map directly to `Vec::new()`.][70632] This allows
`vec![]` to be able to be used in `const` contexts.
- [`convert::Infallible` now implements `Hash`.][70281]
- [`OsString` now implements `DerefMut` and `IndexMut` returning
a `&mut OsStr`.][70048]
- [Unicode 13 is now supported.][69929]
- [`String` now implements `From<&mut str>`.][69661]
- [`IoSlice` now implements `Copy`.][69403]
- [`Vec<T>` now implements `From<[T; N]>`.][68692] Where `N` is less than 32.
Update RELEASES.md
2020-05-29 17:36:50 +08:00
- [`proc_macro::LexError` now implements `fmt::Display` and `Error`.][68899]
- [`from_le_bytes`, `to_le_bytes`, `from_be_bytes`, and `to_be_bytes` methods are
now `const` for all integer types.][69373]
Update RELEASES.md for 1.44.0
2020-05-09 08:13:02 +08:00

- [`f32::to_int_unchecked`]
- [`f64::to_int_unchecked`]
- [`Layout::align_to`]
- [`Layout::pad_to_align`]
- [`Layout::array`]
Cargo
-----
- [Added the `cargo tree` command which will print a tree graph of
your dependencies.][cargo/8062] E.g.
```
mdbook v0.3.2 (/Users/src/rust/mdbook)
├── ammonia v3.0.0

the version in the sidebar.][69494]
Compatibility Notes
-------------------
- [Rustc now correctly generates static libraries on Windows GNU targets with
the `.a` extension, rather than the previous `.lib`.][70937]
- [Removed the `-C no_integrated_as` flag from rustc.][70345]
- [The `file_name` property in JSON output of macro errors now points the actual
source file rather than the previous format of `<NAME macros>`.][70969]
**Note:** this may not point a file that actually exists on the user's system.
- [The minimum required external LLVM version has been bumped to LLVM 8.][71147]
Update RELEASES.md
2020-05-29 17:36:50 +08:00
- [`mem::{zeroed, uninitialised, MaybeUninit}` will now panic when used with types
that do not allow zero initialization such as `NonZeroU8`.][66059] This was
previously a warning.

These changes provide no direct user facing benefits, but represent significant
improvements to the internals and overall performance of rustc and
related tools.
- [dep_graph Avoid allocating a set on when the number reads are small.][69778]

2020-03-24 20:24:20 +08:00
everything in the `unused` lint group **including** `unused-variables` since

- [rustc will now prefer your system MinGW libraries over its bundled libraries
if they are available on `windows-gnu`.][67429]
- [rustc now buffers errors/warnings printed in JSON.][69227]

your environment.][cargo/7823]
- [Cargo will now set `CARGO_BIN_EXE_<name>` pointing to a binary's
executable path when running integration tests or benchmarks.][cargo/7697]
`<name>` is the name of your binary as-is e.g. If you wanted the executable
path for a binary named `my-program`you would use `env!("CARGO_BIN_EXE_my-program")`.

Version 1.42.0 (2020-03-12)
==========================
Language
--------
- [You can now use the slice pattern syntax with subslices.][67712] e.g.
```rust
fn foo(words: &[&str]) {
match words {
["Hello", "World", "!", ..] => println!("Hello World!"),
["Foo", "Bar", ..] => println!("Baz"),

2020-02-24 01:04:48 +08:00
- [You can now use `#[repr(transparent)]` on univariant `enum`s.][68122] Meaning
that you can create an enum that has the exact layout and ABI of the type
it contains.
- [There are some *syntax-only* changes:][67131]
- `default` is syntactically allowed before items in `trait` definitions.
- Items in `impl`s (i.e. `const`s, `type`s, and `fn`s) may syntactically
leave out their bodies in favor of `;`.
- Bounds on associated types in `impl`s are now syntactically allowed
(e.g. `type Foo: Ord;`).
- `...` (the C-variadic type) may occur syntactically directly as the type of
any function parameter.

Update RELEASES.md for 1.41.0
2020-01-06 20:04:14 +08:00
Version 1.41.0 (2020-01-30)
===========================
Language
--------
- [You can now pass type parameters to foreign items when implementing
traits.][65879] E.g. You can now write `impl<T> From<Foo> for Vec<T> {}`.
- [You can now arbitrarily nest receiver types in the `self` position.][64325] E.g. you can
now write `fn foo(self: Box<Box<Self>>) {}`. Previously only `Self`, `&Self`,
`&mut Self`, `Arc<Self>`, `Rc<Self>`, and `Box<Self>` were allowed.
- [You can now use any valid identifier in a `format_args` macro.][66847]
Previously identifiers starting with an underscore were not allowed.
- [Visibility modifiers (e.g. `pub`) are now syntactically allowed on trait items and
enum variants.][66183] These are still rejected semantically, but
can be seen and parsed by procedural macros and conditional compilation.
Compiler
--------
- [Rustc will now warn if you have unused loop `'label`s.][66325]
- [Removed support for the `i686-unknown-dragonfly` target.][67255]
- [Added tier 3 support\* for the `riscv64gc-unknown-linux-gnu` target.][66661]
- [You can now pass an arguments file passing the `@path` syntax
to rustc.][66172] Note that the format differs somewhat from what is
found in other tooling; please see [the documentation][argfile-docs] for
more information.
- [You can now provide `--extern` flag without a path, indicating that it is
available from the search path or specified with an `-L` flag.][64882]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.

Libraries
---------
- [The `core::panic` module is now stable.][66771] It was already stable
through `std`.
- [`NonZero*` numerics now implement `From<NonZero*>` if it's a smaller integer
width.][66277] E.g. `NonZeroU16` now implements `From<NonZeroU8>`.
- [`MaybeUninit<T>` now implements `fmt::Debug`.][65013]
Stabilized APIs
---------------
- [`Result::map_or`]
- [`Result::map_or_else`]
- [`std::rc::Weak::weak_count`]
- [`std::rc::Weak::strong_count`]
- [`std::sync::Weak::weak_count`]

Cargo
-----
- [Cargo will now document all the private items for binary crates
by default.][cargo/7593]
- [`cargo-install` will now reinstall the package if it detects that it is out
of date.][cargo/7560]
- [Cargo.lock now uses a more git friendly format that should help to reduce
merge conflicts.][cargo/7579]
- [You can now override specific dependencies's build settings][cargo/7591] E.g.
Demonstrate final build-override syntax
2020-01-28 23:53:21 +08:00
`[profile.dev.package.image] opt-level = 2` sets the `image` crate's

their dependencies.
Misc
----
- [You can now specify `edition` in documentation code blocks to compile the block
for that edition.][66238] E.g. `edition2018` tells rustdoc that the code sample
should be compiled the 2018 edition of Rust.
- [You can now provide custom themes to rustdoc with `--theme`, and check the
current theme with `--check-theme`.][54733]
Update RELEASES.md
2020-01-22 02:12:39 +08:00

Compatibility Notes
-------------------
- [As previously announced 1.41.0 will be the last tier 1 release for 32-bit
Apple targets.][apple-32bit-drop] This means that the source code is still
available to build, but the targets are no longer being tested and release
binaries for those platforms will no longer be distributed by the Rust project.

Update RELEASES.md for 1.40.0
2019-11-14 01:17:02 +08:00
Version 1.40.0 (2019-12-19)
===========================
Language
--------
- [You can now use tuple `struct`s and tuple `enum` variant's constructors in
`const` contexts.][65188] e.g.
```rust
pub struct Point(i32, i32);
const ORIGIN: Point = {
let constructor = Point;
constructor(0, 0)
};
```
- [You can now mark `struct`s, `enum`s, and `enum` variants with the `#[non_exhaustive]` attribute to
indicate that there may be variants or fields added in the future.][64639]
For example this requires adding a wild-card branch (`_ => {}`) to any match
statements on a non-exhaustive `enum`. [(RFC 2008)]
- [You can now use function-like procedural macros in `extern` blocks and in
type positions.][63931] e.g. `type Generated = macro!();`
- [Function-like and attribute procedural macros can now emit
`macro_rules!` items, so you can now have your macros generate macros.][64035]
- [The `meta` pattern matcher in `macro_rules!` now correctly matches the modern
attribute syntax.][63674] For example `(#[$m:meta])` now matches `#[attr]`,
`#[attr{tokens}]`, `#[attr[tokens]]`, and `#[attr(tokens)]`.
Compiler
--------
- [Added tier 3 support\* for the
`thumbv7neon-unknown-linux-musleabihf` target.][66103]
- [Added tier 3 support for the
`aarch64-unknown-none-softfloat` target.][64589]
- [Added tier 3 support for the `mips64-unknown-linux-muslabi64`, and
`mips64el-unknown-linux-muslabi64` targets.][65843]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.

---------
- [The `is_power_of_two` method on unsigned numeric types is now a `const` function.][65092]

Cargo
-----
- [Cargo will now always display warnings, rather than only on
fresh builds.][cargo/7450]
- [Feature flags (except `--all-features`) passed to a virtual workspace will
now produce an error.][cargo/7507] Previously these flags were ignored.
- [You can now publish `dev-dependencies` without including
a `version`.][cargo/7333]
Misc
----
- [You can now specify the `#[cfg(doctest)]` attribute to include an item only
when running documentation tests with `rustdoc`.][63803]
Compatibility Notes
-------------------
- [As previously announced, any previous NLL warnings in the 2015 edition are
now hard errors.][64221]
- [The `include!` macro will now warn if it failed to include the
entire file.][64284] The `include!` macro unintentionally only includes the
first _expression_ in a file, and this can be unintuitive. This will become

either a hard error in a future release, or the behavior may be fixed to include all expressions as expected.
Update RELEASES.md for 1.40.0
2019-11-14 01:17:02 +08:00
- [Using `#[inline]` on function prototypes and consts now emits a warning under
`unused_attribute` lint.][65294] Using `#[inline]` anywhere else inside traits
or `extern` blocks now correctly emits a hard error.

Updated RELEASES.md for 1.39.0
2019-09-29 02:10:39 +08:00
Version 1.39.0 (2019-11-07)
===========================
Language
--------
- [You can now create `async` functions and blocks with `async fn`, `async move {}`, and
`async {}` respectively, and you can now call `.await` on async expressions.][63209]
- [You can now use certain attributes on function, closure, and function pointer
parameters.][64010] These attributes include `cfg`, `cfg_attr`, `allow`, `warn`,
`deny`, `forbid` as well as inert helper attributes used by procedural macro
attributes applied to items. e.g.
```rust
fn len(
#[cfg(windows)] slice: &[u16],
#[cfg(not(windows))] slice: &[u8],
) -> usize {
slice.len()
}
```
- [You can now take shared references to bind-by-move patterns in the `if` guards
of `match` arms.][63118] e.g.
```rust
fn main() {
let array: Box<[u8; 4]> = Box::new([1, 2, 3, 4]);
match array {
nums
// ---- `nums` is bound by move.
if nums.iter().sum::<u8>() == 10
// ^------ `.iter()` implicitly takes a reference to `nums`.
=> {
drop(nums);
// ----------- Legal as `nums` was bound by move and so we have ownership.
}
_ => unreachable!(),
}
}
```
Compiler
--------
- [Added tier 3\* support for the `i686-unknown-uefi` target.][64334]
- [Added tier 3 support for the `sparc64-unknown-openbsd` target.][63595]
- [rustc will now trim code snippets in diagnostics to fit in your terminal.][63402]
**Note** Cargo currently doesn't use this feature. Refer to
[cargo#7315][cargo/7315] to track this feature's progress.
- [You can now pass `--show-output` argument to test binaries to print the
output of successful tests.][62600]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.
Libraries
---------
- [`Vec::new` and `String::new` are now `const` functions.][64028]
- [`LinkedList::new` is now a `const` function.][63684]
- [`str::len`, `[T]::len` and `str::as_bytes` are now `const` functions.][63770]
- [The `abs`, `wrapping_abs`, and `overflowing_abs` numeric functions are
now `const`.][63786]
Stabilized APIs
---------------
- [`Pin::into_inner`]
- [`Instant::checked_duration_since`]
- [`Instant::saturating_duration_since`]
Cargo
-----
- [You can now publish git dependencies if supplied with a `version`.][cargo/7237]
- [The `--all` flag has been renamed to `--workspace`.][cargo/7241] Using
`--all` is now deprecated.
Misc
----
- [You can now pass `-Clinker` to rustdoc to control the linker used
for compiling doctests.][63834]
Compatibility Notes
-------------------
- [Code that was previously accepted by the old borrow checker, but rejected by
the NLL borrow checker is now a hard error in Rust 2018.][63565] This was
previously a warning, and will also become a hard error in the Rust 2015
edition in the 1.40.0 release.
- [`rustdoc` now requires `rustc` to be installed and in the same directory to
run tests.][63827] This should improve performance when running a large
amount of doctests.
- [The `try!` macro will now issue a deprecation warning.][62672] It is
recommended to use the `?` operator instead.
- [`asinh(-0.0)` now correctly returns `-0.0`.][63698] Previously this
returned `0.0`.

Updated RELEASES.md for 1.37.0
2019-07-13 20:15:01 +08:00
Version 1.37.0 (2019-08-15)
==========================
Language
--------
- `#[must_use]` will now warn if the type is contained in a [tuple][61100],
[`Box`][62228], or an [array][62235] and unused.
- [You can now use the `cfg` and `cfg_attr` attributes on
generic parameters.][61547]
- [You can now use enum variants through type alias.][61682] e.g. You can
write the following:
```rust
type MyOption = Option<u8>;
fn increment_or_zero(x: MyOption) -> u8 {
match x {
MyOption::Some(y) => y + 1,
MyOption::None => 0,
}
}
```
- [You can now use `_` as an identifier for consts.][61347] e.g. You can write
`const _: u32 = 5;`.
- [You can now use `#[repr(align(X)]` on enums.][61229]
RELEASES.md: ? is one of three Kleene operators The slash and quotes in ?/“Kleene” appeared to define “Kleene” as the name for the ? operator, which is not the case. Rust has three Kleene operators *, +, ?. (Pointed out by /u/Sharlinator on Reddit.) Signed-off-by: Anders Kaseorg <andersk@mit.edu>
2019-08-14 02:00:32 +08:00
- [The `?` Kleene macro operator is now available in the
Updated RELEASES.md for 1.37.0
2019-07-13 20:15:01 +08:00
2015 edition.][60932]
Compiler
--------
- [You can now enable Profile-Guided Optimization with the `-C profile-generate`
and `-C profile-use` flags.][61268] For more information on how to use profile
guided optimization, please refer to the [rustc book][rustc-book-pgo].
- [The `rust-lldb` wrapper script should now work again.][61827]
Libraries
---------
- [`mem::MaybeUninit<T>` is now ABI-compatible with `T`.][61802]
Stabilized APIs
---------------
- [`BufReader::buffer`]
- [`BufWriter::buffer`]
- [`Cell::from_mut`]

Updated RELEASES.md for 1.36.0 Co-Authored-By: Taiki Endo <te316e89@gmail.com> Co-Authored-By: Jonas Schievink <jonasschievink@gmail.com> Co-Authored-By: Torbjørn Birch Moltu <t.b.moltu@lyse.net>
2019-06-23 17:45:06 +08:00
Version 1.36.0 (2019-07-04)
==========================
Language
--------
- [Non-Lexical Lifetimes are now enabled on the 2015 edition.][59114]
- [The order of traits in trait objects no longer affects the semantics of that
object.][59445] e.g. `dyn Send + fmt::Debug` is now equivalent to
`dyn fmt::Debug + Send`, where this was previously not the case.
Libraries
---------
- [`HashMap`'s implementation has been replaced with `hashbrown::HashMap` implementation.][58623]
- [`TryFromSliceError` now implements `From<Infallible>`.][60318]
- [`mem::needs_drop` is now available as a const fn.][60364]
- [`alloc::Layout::from_size_align_unchecked` is now available as a const fn.][60370]
- [`String` now implements `BorrowMut<str>`.][60404]
- [`io::Cursor` now implements `Default`.][60234]
- [Both `NonNull::{dangling, cast}` are now const fns.][60244]
- [The `alloc` crate is now stable.][59675] `alloc` allows you to use a subset
of `std` (e.g. `Vec`, `Box`, `Arc`) in `#![no_std]` environments if the
environment has access to heap memory allocation.
- [`String` now implements `From<&String>`.][59825]
- [You can now pass multiple arguments to the `dbg!` macro.][59826] `dbg!` will
return a tuple of each argument when there is multiple arguments.
- [`Result::{is_err, is_ok}` are now `#[must_use]` and will produce a warning if
not used.][59648]

Version 1.35.0 (2019-05-23)
==========================
Language
--------
- [`FnOnce`, `FnMut`, and the `Fn` traits are now implemented for `Box<FnOnce>`,
`Box<FnMut>`, and `Box<Fn>` respectively.][59500]
- [You can now coerce closures into unsafe function pointers.][59580] e.g.
```rust
unsafe fn call_unsafe(func: unsafe fn()) {
func()
}
pub fn main() {
unsafe { call_unsafe(|| {}); }
}
```
Compiler
--------
- [Added the `armv6-unknown-freebsd-gnueabihf` and
`armv7-unknown-freebsd-gnueabihf` targets.][58080]
- [Added the `wasm32-unknown-wasi` target.][59464]
Libraries

- [`alloc::System` now implements `Default`.][59451]
- [Expanded `Debug` output (`{:#?}`) for structs now has a trailing comma on the
last field.][59076]
- [`char::{ToLowercase, ToUppercase}` now
implement `ExactSizeIterator`.][58778]
- [All `NonZero` numeric types now implement `FromStr`.][58717]
- [Removed the `Read` trait bounds
on the `BufReader::{get_ref, get_mut, into_inner}` methods.][58423]
- [You can now call the `dbg!` macro without any parameters to print the file
and line where it is called.][57847]
- [In place ASCII case conversions are now up to 4× faster.][59283]
e.g. `str::make_ascii_lowercase`
- [`hash_map::{OccupiedEntry, VacantEntry}` now implement `Sync`
and `Send`.][58369]

==========================
Language
--------
Update RELEASES.md
2019-04-02 16:09:48 +08:00
- [You can now use `#[deprecated = "reason"]`][58166] as a shorthand for
`#[deprecated(note = "reason")]`. This was previously allowed by mistake

2019-04-01 16:49:28 +08:00
but had no effect.
- [You can now accept token streams in `#[attr()]`,`#[attr[]]`, and
`#[attr{}]` procedural macros.][57367]

crate's root into the extern prelude.
Compiler
--------
- [You can now target `riscv64imac-unknown-none-elf` and
`riscv64gc-unknown-none-elf`.][58406]
- [You can now enable linker plugin LTO optimisations with
`-C linker-plugin-lto`.][58057] This allows rustc to compile your Rust code
into LLVM bitcode allowing LLVM to perform LTO optimisations across C/C++ FFI
boundaries.
- [You can now target `powerpc64-unknown-freebsd`.][57809]
Libraries
---------
- [The trait bounds have been removed on some of `HashMap<K, V, S>`'s and
`HashSet<T, S>`'s basic methods.][58370] Most notably you no longer require
the `Hash` trait to create an iterator.

methods.][58421] Most notably you no longer require the `Ord` trait to create
an iterator.
- [The methods `overflowing_neg` and `wrapping_neg` are now `const` functions
for all numeric types.][58044]
- [Indexing a `str` is now generic over all types that
implement `SliceIndex<str>`.][57604]
- [`str::trim`, `str::trim_matches`, `str::trim_{start, end}`, and
`str::trim_{start, end}_matches` are now `#[must_use]`][57106] and will
produce a warning if their returning type is unused.
- [The methods `checked_pow`, `saturating_pow`, `wrapping_pow`, and
`overflowing_pow` are now available for all numeric types.][57873] These are

Updated RELEASES.md for 1.32.0
2019-01-09 23:12:12 +08:00
Version 1.32.0 (2019-01-17)
==========================
Language
--------
#### 2018 edition
- [You can now use the `?` operator in macro definitions.][56245] The `?`
operator allows you to specify zero or one repetitions similar to the `*` and
`+` operators.
Update RELEASES.md
2019-01-11 06:07:38 +08:00
- [Module paths with no leading keyword like `super`, `self`, or `crate`, will
now always resolve to the item (`enum`, `struct`, etc.) available in the
module if present, before resolving to a external crate or an item the prelude.][56759]
E.g.
```rust
enum Color { Red, Green, Blue }
use Color::*;
```
Updated RELEASES.md for 1.32.0
2019-01-09 23:12:12 +08:00
#### All editions
- [You can now match against `PhantomData<T>` types.][55837]
- [You can now match against literals in macros with the `literal`
specifier.][56072] This will match against a literal of any type.
E.g. `1`, `'A'`, `"Hello World"`
Fix release note problems noticed after merging.
2019-02-28 08:09:32 +08:00
- [Self can now be used as a constructor and pattern for unit and tuple structs.][56365] E.g.
Updated RELEASES.md for 1.32.0
2019-01-09 23:12:12 +08:00
```rust
struct Point(i32, i32);
impl Point {
pub fn new(x: i32, y: i32) -> Self {
Self(x, y)
}
pub fn is_origin(&self) -> bool {
match self {
Self(0, 0) => true,
_ => false,
}
}
}
```
- [Self can also now be used in type definitions.][56366] E.g.
```rust
enum List<T>
where

}
```
Update RELEASES.md
2019-01-10 17:08:07 +08:00
- [You can now mark traits with `#[must_use]`.][55663] This provides a warning if
a `impl Trait` or `dyn Trait` is returned and unused in the program.
Updated RELEASES.md for 1.32.0
2019-01-09 23:12:12 +08:00
Compiler
--------
- [The default allocator has changed from jemalloc to the default allocator on
your system.][55238] The compiler itself on Linux & macOS will still use

2019-01-10 17:08:32 +08:00
jemalloc, but programs compiled with it will use the system allocator.
Updated RELEASES.md for 1.32.0
2019-01-09 23:12:12 +08:00
- [Added the `aarch64-pc-windows-msvc` target.][55702]
Libraries
---------
- [`PathBuf` now implements `FromStr`.][55148]
- [`Box<[T]>` now implements `FromIterator<T>`.][55843]
- [The `dbg!` macro has been stabilized.][56395] This macro enables you to
easily debug expressions in your rust program. E.g.
```rust
let a = 2;
let b = dbg!(a * 2) + 1;
// ^-- prints: [src/main.rs:4] a * 2 = 4
assert_eq!(b, 5);
```

`const` context.

Updated RELEASES.md for 1.31.0
2018-11-05 01:48:30 +08:00
- [New lifetime elision rules now allow for eliding lifetimes in functions and
impl headers.][54778] E.g. `impl<'a> Reader for BufReader<'a> {}` can now be
`impl Reader for BufReader<'_> {}`. Lifetimes are still required to be defined
in structs.
- [You can now define and use `const` functions.][54835] These are currently
a strict minimal subset of the [const fn RFC][RFC-911]. Refer to the
[language reference][const-reference] for what exactly is available.
- [You can now use tool lints, which allow you to scope lints from external
tools using attributes.][54870] E.g. `#[allow(clippy::filter_map)]`.
- [`#[no_mangle]` and `#[export_name]` attributes can now be located anywhere in
a crate, not just in exported functions.][54451]
- [You can now use parentheses in pattern matches.][54497]

Updated RELEASES.md for 1.31.0
2018-11-05 01:48:30 +08:00
`From` trait.][54240] E.g. `u8` now implements `From<NonZeroU8>`.
- [You can now convert a `&Option<T>` into `Option<&T>` and `&mut Option<T>`
into `Option<&mut T>` using the `From` trait.][53218]
- [You can now multiply (`*`) a `time::Duration` by a `u32`.][52813]

===========================
Language
--------
Updated RELEASES
2018-06-26 20:41:32 +08:00
- [The `#[repr(transparent)]` attribute is now stable.][51562] This attribute
Updated RELEASES for 1.28.0
2018-06-23 04:23:17 +08:00
allows a Rust newtype wrapper (`struct NewType<T>(T);`) to be represented as
the inner type across Foreign Function Interface (FFI) boundaries.
- [The keywords `pure`, `sizeof`, `alignof`, and `offsetof` have been unreserved
and can now be used as identifiers.][51196]
Updated RELEASES
2018-06-26 20:41:32 +08:00
- [The `GlobalAlloc` trait and `#[global_allocator]` attribute are now
stable.][51241] This will allow users to specify a global allocator for

their program.
- [Unit test functions marked with the `#[test]` attribute can now return
`Result<(), E: Debug>` in addition to `()`.][51298]
Updated RELEASES
2018-06-26 20:41:32 +08:00
- [The `lifetime` specifier for `macro_rules!` is now stable.][50385] This
allows macros to easily target lifetimes.

Compiler
--------
Updated RELEASES
2018-06-26 20:41:32 +08:00
- [The `s` and `z` optimisation levels are now stable.][50265] These optimisations
Updated RELEASES for 1.28.0
2018-06-23 04:23:17 +08:00
prioritise making smaller binary sizes. `z` is the same as `s` with the
exception that it does not vectorise loops, which typically results in an even
smaller binary.
Updated RELEASES
2018-06-26 20:41:32 +08:00
- [The short error format is now stable.][49546] Specified with
Updated RELEASES for 1.28.0
2018-06-23 04:23:17 +08:00
`--error-format=short` this option will provide a more compressed output of
rust error messages.
- [Added a lint warning when you have duplicated `macro_export`s.][50143]
- [Reduced the number of allocations in the macro parser.][50855] This can
improve compile times of macro heavy crates on average by 5%.
Libraries
---------
- [Implemented `Default` for `&mut str`.][51306]
- [Implemented `From<bool>` for all integer and unsigned number types.][50554]
- [Implemented `Extend` for `()`.][50234]
- [The `Debug` implementation of `time::Duration` should now be more easily
human readable.][50364] Previously a `Duration` of one second would printed as
Update RELEASES.md
2018-06-23 05:36:01 +08:00
`Duration { secs: 1, nanos: 0 }` and will now be printed as `1s`.
Updated RELEASES for 1.28.0
2018-06-23 04:23:17 +08:00
- [Implemented `From<&String>` for `Cow<str>`, `From<&Vec<T>>` for `Cow<[T]>`,
`From<Cow<CStr>>` for `CString`, `From<CString>, From<CStr>, From<&CString>`
for `Cow<CStr>`, `From<OsString>, From<OsStr>, From<&OsString>` for
`Cow<OsStr>`, `From<&PathBuf>` for `Cow<Path>`, and `From<Cow<Path>>`
for `PathBuf`.][50170]

and `Wrapping<i128>`.][50465]
Updated RELEASES for 1.28.0
2018-06-23 04:23:17 +08:00
- [`DirEntry::metadata` now uses `fstatat` instead of `lstat` when

Updated RELEASES for 1.28.0
2018-06-23 04:23:17 +08:00
Updated RELEASES.md for 1.27.0
2018-06-01 06:32:20 +08:00
Version 1.27.0 (2018-06-21)
==========================
Language
--------
- [Removed 'proc' from the reserved keywords list.][49699] This allows `proc` to

be used as an identifier.
Updated RELEASES.md for 1.27.0
2018-06-01 06:32:20 +08:00
- [The dyn syntax is now available.][49968] This syntax is equivalent to the
bare `Trait` syntax, and should make it clearer when being used in tandem with

2018-10-23 19:53:48 +08:00
`impl Trait` because it is equivalent to the following syntax:
Updated RELEASES.md for 1.27.0
2018-06-01 06:32:20 +08:00
`&Trait == &dyn Trait`, `&mut Trait == &mut dyn Trait`, and
`Box<Trait> == Box<dyn Trait>`.
- [Attributes on generic parameters such as types and lifetimes are
now stable.][48851] e.g.
`fn foo<#[lifetime_attr] 'a, #[type_attr] T: 'a>() {}`
- [The `#[must_use]` attribute can now also be used on functions as well as
types.][48925] It provides a lint that by default warns users when the
value returned by a function has not been used.
Compiler
--------
1.27 actually added the `armv5te-unknown-linux-musleabi` target The PR title says `armv5te-unknown-linux-musl`, but it looks like the final code merge renamed the target to `armv5te-unknown-linux-musleabi`. `rustup` reports this as correct as well. The [Rust Platform Support](https://forge.rust-lang.org/platform-support.html) page needs this added as well, but I'm not certain what codebase that is generated from.
2018-08-01 23:24:18 +08:00
- [Added the `armv5te-unknown-linux-musleabi` target.][50423]
Updated RELEASES.md for 1.27.0
2018-06-01 06:32:20 +08:00
Libraries
---------
- [SIMD (Single Instruction Multiple Data) on x86/x86_64 is now stable.][49664]
This includes [`arch::x86`] & [`arch::x86_64`] modules which contain
SIMD intrinsics, a new macro called `is_x86_feature_detected!`, the
`#[target_feature(enable="")]` attribute, and adding `target_feature = ""` to
the `cfg` attribute.
- [A lot of methods for `[u8]`, `f32`, and `f64` previously only available in
std are now available in core.][49896]
- [The generic `Rhs` type parameter on `ops::{Shl, ShlAssign, Shr}` now defaults
to `Self`.][49630]
- [`std::str::replace` now has the `#[must_use]` attribute][50177] to clarify
that the operation isn't done in place.
- [`Clone::clone`, `Iterator::collect`, and `ToOwned::to_owned` now have
the `#[must_use]` attribute][49533] to warn about unused potentially
expensive allocations.

2018-06-01 06:32:20 +08:00
- [Cargo will now cache compiler information.][cargo/5359] This can be disabled by
setting `CARGO_CACHE_RUSTC_INFO=0` in your environment.
Misc
----
- [Added “The Rustc book” into the official documentation.][49707]
[“The Rustc book”] documents and teaches how to use the rustc compiler.
- [All books available on `doc.rust-lang.org` are now searchable.][49623]
Compatibility Notes
-------------------
- [Calling a `CharExt` or `StrExt` method directly on core will no longer
work.][49896] e.g. `::core::prelude::v1::StrExt::is_empty("")` will not
compile, `"".is_empty()` will still compile.
- [`Debug` output on `atomic::{AtomicBool, AtomicIsize, AtomicPtr, AtomicUsize}`

`print!("{:?}", AtomicBool::new(true))` will print `true`,
Updated RELEASES.md for 1.27.0
2018-06-01 06:32:20 +08:00
not `AtomicBool(true)`.
- [The maximum number for `repr(align(N))` is now 2²⁹.][50378] Previously you
could enter higher numbers but they were not supported by LLVM. Up to 512MB
alignment should cover all use cases.
Add Error::description soft-deprecation to RELEASES
2018-09-09 06:36:17 +08:00
- The `.description()` method on the `std::error::Error` trait
[has been soft-deprecated][50163]. It is no longer required to implement it.

```
Compiler
--------
- [LLD is now used as the default linker for `wasm32-unknown-unknown`.][48125]

Update release notes for 1.19.0
2017-07-21 02:42:15 +08:00
Version 1.19.0 (2017-07-20)
===========================
Language
--------
- [Numeric fields can now be used for creating tuple structs.][41145] [RFC 1506]
For example `struct Point(u32, u32); let x = Point { 0: 7, 1: 0 };`.
- [Macro recursion limit increased to 1024 from 64.][41676]
- [Added lint for detecting unused macros.][41907]
- [`loop` can now return a value with `break`.][42016] [RFC 1624]
For example: `let x = loop { break 7; };`
- [C compatible `union`s are now available.][42068] [RFC 1444] They can only
contain `Copy` types and cannot have a `Drop` implementation.
Example: `union Foo { bar: u8, baz: usize }`
- [Non capturing closures can now be coerced into `fn`s,][42162] [RFC 1558]
Example: `let foo: fn(u8) -> u8 = |v: u8| { v };`
Compiler
--------
- [Add support for bootstrapping the Rust compiler toolchain on Android.][41370]
- [Change `arm-linux-androideabi` to correspond to the `armeabi`
official ABI.][41656] If you wish to continue targeting the `armeabi-v7a` ABI
you should use `--target armv7-linux-androideabi`.
- [Fixed ICE when removing a source file between compilation sessions.][41873]
- [Minor optimisation of string operations.][42037]
- [Compiler error message is now `aborting due to previous error(s)` instead of
`aborting due to N previous errors`][42150] This was previously inaccurate and
would only count certain kinds of errors.
- [The compiler now supports Visual Studio 2017][42225]
- [The compiler is now built against LLVM 4.0.1 by default][42948]
- [Added a lot][42264] of [new error codes][42302]
- [Added `target-feature=+crt-static` option][37406] [RFC 1721] Which allows
libraries with C Run-time Libraries(CRT) to be statically linked.
- [Fixed various ARM codegen bugs][42740]
Libraries
---------
- [`String` now implements `FromIterator<Cow<'a, str>>` and
`Extend<Cow<'a, str>>`][41449]
- [`Vec` now implements `From<&mut [T]>`][41530]
- [`Box<[u8]>` now implements `From<Box<str>>`][41258]
- [`SplitWhitespace` now implements `Clone`][41659]
- [`[u8]::reverse` is now 5x faster and `[u16]::reverse` is now
1.5x faster][41764]
- [`eprint!` and `eprintln!` macros added to prelude.][41192] Same as the `print!`
macros, but for printing to stderr.
Stabilized APIs
---------------
- [`OsString::shrink_to_fit`]
- [`cmp::Reverse`]
- [`Command::envs`]
- [`thread::ThreadId`]
Cargo
-----
- [Build scripts can now add environment variables to the environment
the crate is being compiled in.
Example: `println!("cargo:rustc-env=FOO=bar");`][cargo/3929]
- [Subcommands now replace the current process rather than spawning a new
child process][cargo/3970]
- [Workspace members can now accept glob file patterns][cargo/3979]
- [Added `--all` flag to the `cargo bench` subcommand to run benchmarks of all
the members in a given workspace.][cargo/3988]
- [Updated `libssh2-sys` to 0.2.6][cargo/4008]
- [Target directory path is now in the cargo metadata][cargo/4022]
- [Cargo no longer checks out a local working directory for the
crates.io index][cargo/4026] This should provide smaller file size for the
registry, and improve cloning times, especially on Windows machines.
- [Added an `--exclude` option for excluding certain packages when using the
`--all` option][cargo/4031]
- [Cargo will now automatically retry when receiving a 5xx error
from crates.io][cargo/4032]
- [The `--features` option now accepts multiple comma or space
delimited values.][cargo/4084]
- [Added support for custom target specific runners][cargo/3954]
Misc
----
- [Added `rust-windbg.cmd`][39983] for loading rust `.natvis` files in the
Windows Debugger.
- [Rust will now release XZ compressed packages][rust-installer/57]
- [rustup will now prefer to download rust packages with
XZ compression][rustup/1100] over GZip packages.
- [Added the ability to escape `#` in rust documentation][41785] By adding
additional `#`'s ie. `##` is now `#`
Compatibility Notes
-------------------
- [`MutexGuard<T>` may only be `Sync` if `T` is `Sync`.][41624]
- [`-Z` flags are now no longer allowed to be used on the stable
compiler.][41751] This has been a warning for a year previous to this.
- [As a result of the `-Z` flag change, the `cargo-check` plugin no
longer works][42844]. Users should migrate to the built-in `check`
command, which has been available since 1.16.
- [Ending a float literal with `._` is now a hard error.
Example: `42._` .][41946]
- [Any use of a private `extern crate` outside of its module is now a
hard error.][36886] This was previously a warning.
- [`use ::self::foo;` is now a hard error.][36888] `self` paths are always
relative while the `::` prefix makes a path absolute, but was ignored and the
path was relative regardless.
- [Floating point constants in match patterns is now a hard error][36890]
This was previously a warning.
- [Struct or enum constants that don't derive `PartialEq` & `Eq` used
match patterns is now a hard error][36891] This was previously a warning.
- [Lifetimes named `'_` are no longer allowed.][36892] This was previously
a warning.
- [From the pound escape, lines consisting of multiple `#`s are
now visible][41785]
Reexport -> re-export in prose and documentation comments
2018-01-13 05:41:25 +08:00
- [It is an error to re-export private enum variants][42460]. This is
Update release notes for 1.19.0
2017-07-21 02:42:15 +08:00
known to break a number of crates that depend on an older version of
mustache.
- [On Windows, if `VCINSTALLDIR` is set incorrectly, `rustc` will try
to use it to find the linker, and the build will fail where it did
not previously][42607]

Updated releases notes for 1.18
2017-05-12 22:39:19 +08:00
Version 1.18.0 (2017-06-08)
===========================
Language
--------
- [Stabilize pub(restricted)][40556] `pub` can now accept a module path to
make the item visible to just that module tree. Also accepts the keyword
`crate` to make something public to the whole crate but not users of the
library. Example: `pub(crate) mod utils;`. [RFC 1422].
- [Stabilize `#![windows_subsystem]` attribute][40870] conservative exposure of the
`/SUBSYSTEM` linker flag on Windows platforms. [RFC 1665].
- [Refactor of trait object type parsing][40043] Now `ty` in macros can accept
types like `Write + Send`, trailing `+` are now supported in trait objects,
and better error reporting for trait objects starting with `?Sized`.
- [0e+10 is now a valid floating point literal][40589]
- [Now warns if you bind a lifetime parameter to 'static][40734]
- [Tuples, Enum variant fields, and structs with no `repr` attribute or with
`#[repr(Rust)]` are reordered to minimize padding and produce a smaller
representation in some cases.][40377]
Compiler
--------
- [rustc can now emit mir with `--emit mir`][39891]
- [Improved LLVM IR for trivial functions][40367]
- [Added explanation for E0090(Wrong number of lifetimes are supplied)][40723]
- [rustc compilation is now 15%-20% faster][41469] Thanks to optimisation
opportunities found through profiling
- [Improved backtrace formatting when panicking][38165]
Libraries
---------
- [Specialized `Vec::from_iter` being passed `vec::IntoIter`][40731] if the
iterator hasn't been advanced the original `Vec` is reassembled with no actual
iteration or reallocation.
- [Simplified HashMap Bucket interface][40561] provides performance
improvements for iterating and cloning.
- [Specialize Vec::from_elem to use calloc][40409]
- [Fixed Race condition in fs::create_dir_all][39799]
- [No longer caching stdio on Windows][40516]
- [Optimized insertion sort in slice][40807] insertion sort in some cases
2.50%~ faster and in one case now 12.50% faster.
- [Optimized `AtomicBool::fetch_nand`][41143]
Stabilized APIs
---------------
- [`Child::try_wait`]
- [`HashMap::retain`]
- [`HashSet::retain`]
- [`PeekMut::pop`]
- [`TcpStream::peek`]
- [`UdpSocket::peek`]
- [`UdpSocket::peek_from`]
Cargo
-----
- [Added partial Pijul support][cargo/3842] Pijul is a version control system in Rust.
You can now create new cargo projects with Pijul using `cargo new --vcs pijul`
- [Now always emits build script warnings for crates that fail to build][cargo/3847]
- [Added Android build support][cargo/3885]
- [Added `--bins` and `--tests` flags][cargo/3901] now you can build all programs
of a certain type, for example `cargo build --bins` will build all
binaries.
- [Added support for haiku][cargo/3952]
Misc
----
- [rustdoc can now use pulldown-cmark with the `--enable-commonmark` flag][40338]
fix some typos
2017-11-21 22:33:45 +08:00
- [Added rust-windbg script for better debugging on Windows][39983]
Updated releases notes for 1.18
2017-05-12 22:39:19 +08:00
- [Rust now uses the official cross compiler for NetBSD][40612]
- [rustdoc now accepts `#` at the start of files][40828]
- [Fixed jemalloc support for musl][41168]
Compatibility Notes
-------------------
- [Changes to how the `0` flag works in format!][40241] Padding zeroes are now
always placed after the sign if it exists and before the digits. With the `#`
flag the zeroes are placed after the prefix and before the digits.
- [Due to the struct field optimisation][40377], using `transmute` on structs
that have no `repr` attribute or `#[repr(Rust)]` will no longer work. This has
always been undefined behavior, but is now more likely to break in practice.
- [The refactor of trait object type parsing][40043] fixed a bug where `+` was
receiving the wrong priority parsing things like `&for<'a> Tr<'a> + Send` as
`&(for<'a> Tr<'a> + Send)` instead of `(&for<'a> Tr<'a>) + Send`
- [Overlapping inherent `impl`s are now a hard error][40728]
- [`PartialOrd` and `Ord` must agree on the ordering.][41270]
- [`rustc main.rs -o out --emit=asm,llvm-ir`][41085] Now will output
`out.asm` and `out.ll` instead of only one of the filetypes.
- [ calling a function that returns `Self` will no longer work][41805] when
the size of `Self` cannot be statically determined.
- [rustc now builds with a "pthreads" flavour of MinGW for Windows GNU][40805]
this has caused a few regressions namely:
- Changed the link order of local static/dynamic libraries (respecting the
order on given rather than having the compiler reorder).
- Changed how MinGW is linked, native code linked to dynamic libraries
may require manually linking to the gcc support library (for the native
code itself)

Update release notes for 1.17
2017-04-26 01:43:33 +08:00
Version 1.17.0 (2017-04-27)
===========================
Language
--------
* [The lifetime of statics and consts defaults to `'static`][39265]. [RFC 1623]
* [Fields of structs may be initialized without duplicating the field/variable
names][39761]. [RFC 1682]
* [`Self` may be included in the `where` clause of `impls`][38864]. [RFC 1647]
* [When coercing to an unsized type lifetimes must be equal][40319]. That is,
there is no subtyping between `T` and `U` when `T: Unsize<U>`. For example,
coercing `&mut [&'a X; N]` to `&mut [&'b X]` requires `'a` be equal to
`'b`. Soundness fix.
* [Values passed to the indexing operator, `[]`, automatically coerce][40166]
* [Static variables may contain references to other statics][40027]
Compiler
--------
* [Exit quickly on only `--emit dep-info`][40336]
* [Make `-C relocation-model` more correctly determine whether the linker
creates a position-independent executable][40245]
* [Add `-C overflow-checks` to directly control whether integer overflow
panics][40037]
* [The rustc type checker now checks items on demand instead of in a single
in-order pass][40008]. This is mostly an internal refactoring in support of
future work, including incremental type checking, but also resolves [RFC
1647], allowing `Self` to appear in `impl` `where` clauses.
* [Optimize vtable loads][39995]
* [Turn off vectorization for Emscripten targets][39990]
* [Provide suggestions for unknown macros imported with `use`][39953]
* [Fix ICEs in path resolution][39939]
* [Strip exception handling code on Emscripten when `panic=abort`][39193]
* [Add clearer error message using `&str + &str`][39116]

* [`ffi::FromBytesWithNulError` implements `Error` and `Display`][39960]
* [Specialize `PartialOrd<A> for [A] where A: Ord`][39642]
* [Slightly optimize `slice::sort`][39538]
* [Add `ToString` trait specialization for `Cow<'a, str>` and `String`][39440]
* [`Box<[T]>` implements `From<&[T]> where T: Copy`,
`Box<str>` implements `From<&str>`][39438]
* [`IpAddr` implements `From` for various arrays. `SocketAddr` implements

* [`format!` estimates the needed capacity before writing a string][39356]
* [Support unprivileged symlink creation in Windows][38921]
* [`PathBuf` implements `Default`][38764]
* [Implement `PartialEq<[A]>` for `VecDeque<A>`][38661]
* [`HashMap` resizes adaptively][38368] to guard against DOS attacks
and poor hash functions.

* [Add an option to ignore SSL revocation checking][cargo/3699]
* [Add `cargo run --package`][cargo/3691]
* [Add `required_features`][cargo/3667]
* [Assume `build.rs` is a build script][cargo/3664]
* [Find workspace via `workspace_root` link in containing member][cargo/3562]
Misc
----
* [Documentation is rendered with mdbook instead of the obsolete, in-tree
`rustbook`][39633]
* [The "Unstable Book" documents nightly-only features][ubook]
* [Improve the style of the sidebar in rustdoc output][40265]
* [Configure build correctly on 64-bit CPU's with the armhf ABI][40261]
* [Fix MSP430 breakage due to `i128`][40257]
* [Preliminary Solaris/SPARCv9 support][39903]
* [`rustc` is linked statically on Windows MSVC targets][39837], allowing it to
run without installing the MSVC runtime.
* [`rustdoc --test` includes file names in test names][39788]
* This release includes builds of `std` for `sparc64-unknown-linux-gnu`,
`aarch64-unknown-linux-fuchsia`, and `x86_64-unknown-linux-fuchsia`.
* [Initial support for `aarch64-unknown-freebsd`][39491]
* [Initial support for `i686-unknown-netbsd`][39426]
* [This release no longer includes the old makefile build system][39431]. Rust
is built with a custom build system, written in Rust, and with Cargo.

* [`TypeId` implements `PartialOrd` and `Ord`][38981]
* [`--test-threads=0` produces an error][38945]
* [`rustup` installs documentation by default][40526]
* [The Rust source includes NatVis visualizations][39843]. These can be used by
WinDbg and Visual Studio to improve the debugging experience.
Compatibility Notes
-------------------
* [Rust 1.17 does not correctly detect the MSVC 2017 linker][38584]. As a
workaround, either use MSVC 2015 or run vcvars.bat.
* [When coercing to an unsized type lifetimes must be equal][40319]. That is,
disallow subtyping between `T` and `U` when `T: Unsize<U>`, e.g. coercing
`&mut [&'a X; N]` to `&mut [&'b X]` requires `'a` be equal to `'b`. Soundness
fix.
* [`format!` and `Display::to_string` panic if an underlying formatting
implementation returns an error][40117]. Previously the error was silently
ignored. It is incorrect for `write_fmt` to return an error when writing
to a string.
* [In-tree crates are verified to be unstable][39851]. Previously, some minor
crates were marked stable and could be accessed from the stable toolchain.
* [Rust git source no longer includes vendored crates][39728]. Those that need
to build with vendored crates should build from release tarballs.
* [Fix inert attributes from `proc_macro_derives`][39572]
* [During crate resolution, rustc prefers a crate in the sysroot if two crates
are otherwise identical][39518]. Unlikely to be encountered outside the Rust
build system.
* [Fixed bugs around how type inference interacts with dead-code][39485]. The
existing code generally ignores the type of dead-code unless a type-hint is
provided; this can cause surprising inference interactions particularly around
defaulting. The new code uniformly ignores the result type of dead-code.
* [Tuple-struct constructors with private fields are no longer visible][38932]
* [Lifetime parameters that do not appear in the arguments are now considered
early-bound][38897], resolving a soundness bug (#[32330]). The
`hr_lifetime_in_assoc_type` future-compatibility lint has been in effect since
April of 2016.
* [rustdoc: fix doctests with non-feature crate attributes][38161]
* [Make transmuting from fn item types to pointer-sized types a hard
error][34198]

Release notes for 1.16
2017-02-15 10:52:28 +08:00
Version 1.16.0 (2017-03-16)
===========================
Language
--------
* [The compiler's `dead_code` lint now accounts for type aliases][38051].
* [Uninhabitable enums (those without any variants) no longer permit wildcard
match patterns][38069]
* [Clean up semantics of `self` in an import list][38313]
* [`Self` may appear in `impl` headers][38920]
* [`Self` may appear in struct expressions][39282]
Compiler
--------
* [`rustc` now supports `--emit=metadata`, which causes rustc to emit
a `.rmeta` file containing only crate metadata][38571]. This can be
used by tools like the Rust Language Service to perform
metadata-only builds.
* [Levenshtein based typo suggestions now work in most places, while
previously they worked only for fields and sometimes for local
variables][38927]. Together with the overhaul of "no
resolution"/"unexpected resolution" errors (#[38154]) they result in
large and systematic improvement in resolution diagnostics.
* [Fix `transmute::<T, U>` where `T` requires a bigger alignment than
`U`][38670]
* [rustc: use -Xlinker when specifying an rpath with ',' in it][38798]
* [`rustc` no longer attempts to provide "consider using an explicit
lifetime" suggestions][37057]. They were inaccurate.

RELEASES.md: document 1.16 lifetime elision change Closes #41105.
2017-08-21 03:49:36 +08:00
* Reimplemented lifetime elision. This change was almost entirely compatible
with existing code, but it did close a number of small bugs and loopholes,
as well as being more accepting in some other [cases][41105].

1.15 release notes
2017-01-10 08:44:02 +08:00
Version 1.15.0 (2017-02-02)
===========================
Language
--------
* Basic procedural macros allowing custom `#[derive]`, aka "macros 1.1", are
stable. This allows popular code-generating crates like Serde and Diesel to
work ergonomically. [RFC 1681].
* [Tuple structs may be empty. Unary and empty tuple structs may be instantiated
with curly braces][36868]. Part of [RFC 1506].
* [A number of minor changes to name resolution have been activated][37127].
They add up to more consistent semantics, allowing for future evolution of
Rust macros. Specified in [RFC 1560], see its section on ["changes"] for
details of what is different. The breaking changes here have been transitioned
through the [`legacy_imports`] lint since 1.14, with no known regressions.
* [In `macro_rules`, `path` fragments can now be parsed as type parameter
bounds][38279]
* [`?Sized` can be used in `where` clauses][37791]
* [There is now a limit on the size of monomorphized types and it can be
modified with the `#![type_size_limit]` crate attribute, similarly to
the `#![recursion_limit]` attribute][37789]
Compiler
--------
* [On Windows, the compiler will apply dllimport attributes when linking to
extern functions][37973]. Additional attributes and flags can control which
library kind is linked and its name. [RFC 1717].
* [Rust-ABI symbols are no longer exported from cdylibs][38117]
* [The `--test` flag works with procedural macro crates][38107]
* [Fix `extern "aapcs" fn` ABI][37814]
* [The `-C no-stack-check` flag is deprecated][37636]. It does nothing.
* [The `format!` expander recognizes incorrect `printf` and shell-style
formatting directives and suggests the correct format][37613].
* [Only report one error for all unused imports in an import list][37456]
Compiler Performance
--------------------
* [Avoid unnecessary `mk_ty` calls in `Ty::super_fold_with`][37705]
* [Avoid more unnecessary `mk_ty` calls in `Ty::super_fold_with`][37979]
* [Don't clone in `UnificationTable::probe`][37848]
* [Remove `scope_auxiliary` to cut RSS by 10%][37764]
* [Use small vectors in type walker][37760]
* [Macro expansion performance was improved][37701]
* [Change `HirVec<P<T>>` to `HirVec<T>` in `hir::Expr`][37642]
* [Replace FNV with a faster hash function][37229]
Stabilized APIs
---------------
* [`std::iter::Iterator::min_by`]
* [`std::iter::Iterator::max_by`]
* [`std::os::*::fs::FileExt`]
* [`std::sync::atomic::Atomic*::get_mut`]
* [`std::sync::atomic::Atomic*::into_inner`]
* [`std::vec::IntoIter::as_slice`]
* [`std::vec::IntoIter::as_mut_slice`]
* [`std::sync::mpsc::Receiver::try_iter`]
* [`std::os::unix::process::CommandExt::before_exec`]
* [`std::rc::Rc::strong_count`]
* [`std::rc::Rc::weak_count`]
* [`std::sync::Arc::strong_count`]
* [`std::sync::Arc::weak_count`]
* [`std::char::encode_utf8`]
* [`std::char::encode_utf16`]
* [`std::cell::Ref::clone`]
* [`std::io::Take::into_inner`]
Libraries
---------
* [The standard sorting algorithm has been rewritten for dramatic performance
improvements][38192]. It is a hybrid merge sort, drawing influences from
Timsort. Previously it was a naive merge sort.
* [`Iterator::nth` no longer has a `Sized` bound][38134]
* [`Extend<&T>` is specialized for `Vec` where `T: Copy`][38182] to improve
performance.
* [`chars().count()` is much faster][37888] and so are [`chars().last()`
and `char_indices().last()`][37882]
* [Fix ARM Objective-C ABI in `std::env::args`][38146]
* [Chinese characters display correctly in `fmt::Debug`][37855]
* [Derive `Default` for `Duration`][37699]
* [Support creation of anonymous pipes on WinXP/2k][37677]
* [`mpsc::RecvTimeoutError` implements `Error`][37527]
* [Don't pass overlapped handles to processes][38835]
Cargo
-----
* [In this release, Cargo build scripts no longer have access to the `OUT_DIR`
environment variable at build time via `env!("OUT_DIR")`][cargo/3368]. They
should instead check the variable at runtime with `std::env`. That the value
was set at build time was a bug, and incorrect when cross-compiling. This
change is known to cause breakage.
* [Add `--all` flag to `cargo test`][cargo/3221]
* [Compile statically against the MSVC CRT][cargo/3363]
* [Mix feature flags into fingerprint/metadata shorthash][cargo/3102]
* [Link OpenSSL statically on OSX][cargo/3311]
* [Apply new fingerprinting to build dir outputs][cargo/3310]
* [Test for bad path overrides with summaries][cargo/3336]
* [Require `cargo install --vers` to take a semver version][cargo/3338]
* [Fix retrying crate downloads for network errors][cargo/3348]
* [Implement string lookup for `build.rustflags` config key][cargo/3356]
* [Emit more info on --message-format=json][cargo/3319]
* [Assume `build.rs` in the same directory as `Cargo.toml` is a build script][cargo/3361]
* [Don't ignore errors in workspace manifest][cargo/3409]
* [Fix `--message-format JSON` when rustc emits non-JSON warnings][cargo/3410]
Tooling
-------
* [Test runners (binaries built with `--test`) now support a `--list` argument
that lists the tests it contains][38185]
* [Test runners now support a `--exact` argument that makes the test filter
match exactly, instead of matching only a substring of the test name][38181]
* [rustdoc supports a `--playground-url` flag][37763]
* [rustdoc provides more details about `#[should_panic]` errors][37749]
Misc
----
* [The Rust build system is now written in Rust][37817]. The Makefiles may
continue to be used in this release by passing `--disable-rustbuild` to the
configure script, but they will be deleted soon. Note that the new build
system uses a different on-disk layout that will likely affect any scripts
building Rust.
* [Rust supports i686-unknown-openbsd][38086]. Tier 3 support. No testing or
releases.
* [Rust supports the MSP430][37627]. Tier 3 support. No testing or releases.
* [Rust supports the ARMv5TE architecture][37615]. Tier 3 support. No testing or
releases.
Compatibility Notes
-------------------
* [A number of minor changes to name resolution have been activated][37127].
They add up to more consistent semantics, allowing for future evolution of
Rust macros. Specified in [RFC 1560], see its section on ["changes"] for
details of what is different. The breaking changes here have been transitioned

* [In this release, Cargo build scripts no longer have access to the `OUT_DIR`
environment variable at build time via `env!("OUT_DIR")`][cargo/3368]. They
should instead check the variable at runtime with `std::env`. That the value
was set at build time was a bug, and incorrect when cross-compiling. This
change is known to cause breakage.
* [Higher-ranked lifetimes are no longer allowed to appear _only_ in associated
types][33685]. The [`hr_lifetime_in_assoc_type` lint] has been a warning since
1.10 and is now an error by default. It will become a hard error in the near
future.
* [The semantics relating modules to file system directories are changing in
minor ways][37602]. This is captured in the new `legacy_directory_ownership`
lint, which is a warning in this release, and will become a hard error in the
future.
* [Rust-ABI symbols are no longer exported from cdylibs][38117]
* [Once `Peekable` peeks a `None` it will return that `None` without re-querying
the underlying iterator][37834]

Release notes for 1.9
2016-04-09 09:08:52 +08:00
Version 1.9.0 (2016-05-26)
==========================
Language
--------
* The `#[deprecated]` attribute when applied to an API will generate
warnings when used. The warnings may be suppressed with
`#[allow(deprecated)]`. [RFC 1270].
* [`fn` item types are zero sized, and each `fn` names a unique
type][1.9fn]. This will break code that transmutes `fn`s, so calling
`transmute` on a `fn` type will generate a warning for a few cycles,
then will be converted to an error.
* [Field and method resolution understand visibility, so private
fields and methods cannot prevent the proper use of public fields
and methods][1.9fv].
* [The parser considers unicode codepoints in the
`PATTERN_WHITE_SPACE` category to be whitespace][1.9ws].
Stabilized APIs
---------------
* [`std::panic`]

Libraries
---------
* [`std::sync::Once` is poisoned if its initialization function
fails][1.9o].
* [`cell::Ref` and `cell::RefMut` can contain unsized types][1.9cu].
* [Most types implement `fmt::Debug`][1.9db].
* [The default buffer size used by `BufReader` and `BufWriter` was
reduced to 8K, from 64K][1.9bf]. This is in line with the buffer size
used by other languages.
* [`Instant`, `SystemTime` and `Duration` implement `+=` and `-=`.
`Duration` additionally implements `*=` and `/=`][1.9ta].
* [`Skip` is a `DoubleEndedIterator`][1.9sk].
* [`From<[u8; 4]>` is implemented for `Ipv4Addr`][1.9fi].
* [`Chain` implements `BufRead`][1.9ch].
* [`HashMap`, `HashSet` and iterators are covariant][1.9hc].
Cargo
-----
* [Cargo can now run concurrently][1.9cc].
* [Top-level overrides allow specific revisions of crates to be
overridden through the entire crate graph][1.9ct]. This is intended
to make upgrades easier for large projects, by allowing crates to be
forked temporarily until they've been upgraded and republished.
* [Cargo exports a `CARGO_PKG_AUTHORS` environment variable][1.9cp].
* [Cargo will pass the contents of the `RUSTFLAGS` variable to `rustc`
on the commandline][1.9cf]. `rustc` arguments can also be specified
in the `build.rustflags` configuration key.
Performance
-----------
Fixed wrong link in release notes
2016-09-30 06:26:02 +08:00
* [The time complexity of comparing variables for equivalence during type
style: enhance font of big-O expressions
2016-04-16 16:55:33 +08:00
unification is reduced from _O_(_n_!) to _O_(_n_)][1.9tu]. This leads
grammar: fix Reading this, one item stood out a bit. Small improvements here. . ‘Compile-time’ is not a noun, ‘compilation time’ was meant; . Mathematical formulas are best not rendered as code; . Use the same tense as in other items.
2016-04-16 04:33:50 +08:00
to major compilation time improvement in some scenarios.
Release notes for 1.9
2016-04-09 09:08:52 +08:00
* [`ToString` is specialized for `str`, giving it the same performance
as `to_owned`][1.9ts].
* [Spawning processes with `Command::output` no longer creates extra
threads][1.9sp].
* [`#[derive(PartialEq)]` and `#[derive(PartialOrd)]` emit less code
for C-like enums][1.9cl].
Misc
----
* [Passing the `--quiet` flag to a test runner will produce
much-abbreviated output][1.9q].
* The Rust Project now publishes std binaries for the
`mips-unknown-linux-musl`, `mipsel-unknown-linux-musl`, and
`i586-pc-windows-msvc` targets.
Compatibility Notes
-------------------
* [`std::sync::Once` is poisoned if its initialization function
fails][1.9o].
* [It is illegal to define methods with the same name in overlapping
inherent `impl` blocks][1.9sn].
* [`fn` item types are zero sized, and each `fn` names a unique
type][1.9fn]. This will break code that transmutes `fn`s, so calling
`transmute` on a `fn` type will generate a warning for a few cycles,
then will be converted to an error.
* [Improvements to const evaluation may trigger new errors when integer
literals are out of range][1.9ce].

Release notes for 1.8
2016-04-08 07:16:35 +08:00
Version 1.8.0 (2016-04-14)
==========================
Language
--------
* Rust supports overloading of compound assignment statements like
`+=` by implementing the [`AddAssign`], [`SubAssign`],
[`MulAssign`], [`DivAssign`], [`RemAssign`], [`BitAndAssign`],
[`BitOrAssign`], [`BitXorAssign`], [`ShlAssign`], or [`ShrAssign`]
traits. [RFC 953].
* Empty structs can be defined with braces, as in `struct Foo { }`, in
addition to the non-braced form, `struct Foo;`. [RFC 218].
Libraries
---------
* Stabilized APIs:
Convert collapsed to shortcut reference links
2019-12-26 21:27:55 +08:00
* [`str::encode_utf16`] (renamed from `utf16_units`)
* [`str::EncodeUtf16`] (renamed from `Utf16Units`)
Release notes for 1.8
2016-04-08 07:16:35 +08:00
* [`Ref::map`]
* [`RefMut::map`]
* [`ptr::drop_in_place`]
* [`time::Instant`]
* [`time::SystemTime`]
* [`Instant::now`]
Convert collapsed to shortcut reference links
2019-12-26 21:27:55 +08:00
* [`Instant::duration_since`] (renamed from `duration_from_earlier`)
Release notes for 1.8
2016-04-08 07:16:35 +08:00
* [`Instant::elapsed`]
* [`SystemTime::now`]
Convert collapsed to shortcut reference links
2019-12-26 21:27:55 +08:00
* [`SystemTime::duration_since`] (renamed from `duration_from_earlier`)
Release notes for 1.8
2016-04-08 07:16:35 +08:00
* [`SystemTime::elapsed`]
* Various `Add`/`Sub` impls for `Time` and `SystemTime`
* [`SystemTimeError`]
* [`SystemTimeError::duration`]
* Various impls for `SystemTimeError`
* [`UNIX_EPOCH`]
* [`AddAssign`], [`SubAssign`], [`MulAssign`], [`DivAssign`],
[`RemAssign`], [`BitAndAssign`], [`BitOrAssign`],
[`BitXorAssign`], [`ShlAssign`], [`ShrAssign`].
* [The `write!` and `writeln!` macros correctly emit errors if any of
their arguments can't be formatted][1.8w].
* [Various I/O functions support large files on 32-bit Linux][1.8l].
* [The Unix-specific `raw` modules, which contain a number of
redefined C types are deprecated][1.8r], including `os::raw::unix`,
`os::raw::macos`, and `os::raw::linux`. These modules defined types
such as `ino_t` and `dev_t`. The inconsistency of these definitions
across platforms was making it difficult to implement `std`
correctly. Those that need these definitions should use the `libc`
crate. [RFC 1415].
* The Unix-specific `MetadataExt` traits, including
`os::unix::fs::MetadataExt`, which expose values such as inode
numbers [no longer return platform-specific types][1.8r], but
instead return widened integers. [RFC 1415].
* [`btree_set::{IntoIter, Iter, Range}` are covariant][1.8cv].
* [Atomic loads and stores are not volatile][1.8a].
* [All types in `sync::mpsc` implement `fmt::Debug`][1.8mp].
Performance
-----------
* [Inlining hash functions lead to a 3% compile-time improvement in
some workloads][1.8h].
* When using jemalloc, its symbols are [unprefixed so that it
overrides the libc malloc implementation][1.8h]. This means that for
rustc, LLVM is now using jemalloc, which results in a 6%
compile-time improvement on a specific workload.
* [Avoid quadratic growth in function size due to cleanups][1.8cu].
Misc
----
* [32-bit MSVC builds finally implement unwinding][1.8ms].
i686-pc-windows-msvc is now considered a tier-1 platform.
* [The `--print targets` flag prints a list of supported targets][1.8t].
* [The `--print cfg` flag prints the `cfg`s defined for the current
target][1.8cf].
* [`rustc` can be built with an new Cargo-based build system, written
in Rust][1.8b]. It will eventually replace Rust's Makefile-based
build system. To enable it configure with `configure --rustbuild`.
* [Errors for non-exhaustive `match` patterns now list up to 3 missing
variants while also indicating the total number of missing variants
if more than 3][1.8m].
* [Executable stacks are disabled on Linux and BSD][1.8nx].
* The Rust Project now publishes binary releases of the standard
library for a number of tier-2 targets:
`armv7-unknown-linux-gnueabihf`, `powerpc-unknown-linux-gnu`,
`powerpc64-unknown-linux-gnu`, `powerpc64le-unknown-linux-gnu`
`x86_64-rumprun-netbsd`. These can be installed with
tools such as [multirust][1.8mr].
Cargo
-----
* [`cargo init` creates a new Cargo project in the current
directory][1.8ci]. It is otherwise like `cargo new`.
* [Cargo has configuration keys for `-v` and
`--color`][1.8cc]. `verbose` and `color`, respectively, go in the
`[term]` section of `.cargo/config`.
* [Configuration keys that evaluate to strings or integers can be set
via environment variables][1.8ce]. For example the `build.jobs` key
can be set via `CARGO_BUILD_JOBS`. Environment variables take
precedence over config files.
* [Target-specific dependencies support Rust `cfg` syntax for
describing targets][1.8cfg] so that dependencies for multiple
targets can be specified together. [RFC 1361].
* [The environment variables `CARGO_TARGET_ROOT`, `RUSTC`, and
`RUSTDOC` take precedence over the `build.target-dir`,
`build.rustc`, and `build.rustdoc` configuration values][1.8cv].
* [The child process tree is killed on Windows when Cargo is
killed][1.8ck].
* [The `build.target` configuration value sets the target platform,
like `--target`][1.8ct].
Compatibility Notes
-------------------
* [Unstable compiler flags have been further restricted][1.8u]. Since
1.0 `-Z` flags have been considered unstable, and other flags that
were considered unstable additionally required passing `-Z
unstable-options` to access. Unlike unstable language and library
features though, these options have been accessible on the stable
release channel. Going forward, *new unstable flags will not be
available on the stable release channel*, and old unstable flags
will warn about their usage. In the future, all unstable flags will
be unavailable on the stable release channel.
* [It is no longer possible to `match` on empty enum variants using
the `Variant(..)` syntax][1.8v]. This has been a warning since 1.6.
* The Unix-specific `MetadataExt` traits, including
`os::unix::fs::MetadataExt`, which expose values such as inode
numbers [no longer return platform-specific types][1.8r], but
instead return widened integers. [RFC 1415].
* [Modules sourced from the filesystem cannot appear within arbitrary
Fix conflicting link identifiers
2016-04-12 02:31:00 +08:00
blocks, but only within other modules][1.8mf].
Release notes for 1.8
2016-04-08 07:16:35 +08:00
* [`--cfg` compiler flags are parsed strictly as identifiers][1.8c].
* On Unix, [stack overflow triggers a runtime abort instead of a
SIGSEGV][1.8so].
* [`Command::spawn` and its equivalents return an error if any of
its command-line arguments contain interior `NUL`s][1.8n].
* [Tuple and unit enum variants from other crates are in the type
namespace][1.8tn].
* [On Windows `rustc` emits `.lib` files for the `staticlib` library
type instead of `.a` files][1.8st]. Additionally, for the MSVC
toolchain, `rustc` emits import libraries named `foo.dll.lib`
instead of `foo.lib`.

* [The performance of `LineWriter` (and thus `io::stdout`) was
improved by using `memchr` to search for newlines][1.7m].
* [`f32::to_degrees` and `f32::to_radians` are stable][1.7f]. The

Cargo
-----
* [`cargo rustc` accepts a `--profile` flag that runs `rustc` under
any of the compilation profiles, 'dev', 'bench', or 'test'][1.7cp].
* [The `rerun-if-changed` build script directive no longer causes the
build script to incorrectly run twice in certain scenarios][1.7rr].
Compatibility Notes
-------------------
Move the RFC 1214 breakage to 1.7 compatibility notes
2016-03-01 02:35:43 +08:00
* Soundness fixes to the interactions between associated types and
lifetimes, specified in [RFC 1214], [now generate errors][1.7sf] for
code that violates the new rules. This is a significant change that
is known to break existing code, so it has emitted warnings for the
new error cases since 1.4 to give crate authors time to adapt. The
details of what is changing are subtle; read the RFC for more.
Update release notes for 1.7
2016-01-22 08:02:28 +08:00
* [Several bugs in the compiler's visibility calculations were
fixed][1.7v]. Since this was found to break significant amounts of
code, the new errors will be emitted as warnings for several release
cycles, under the `private_in_public` lint.
* Defaulted type parameters were accidentally accepted in positions
that were not intended. In this release, [defaulted type parameters
appearing outside of type definitions will generate a
warning][1.7d], which will become an error in future releases.
documentation fix in RELEASES.md f32 should probably be denoted as 0.0 as it might improve readability. Signed-off-by: benaryorg <binary@benary.org>
2016-03-18 03:15:22 +08:00
* [Parsing "." as a float results in an error instead of 0][1.7p].
That is, `".".parse::<f32>()` returns `Err`, not `Ok(0.0)`.

Release notes for 1.6
2016-01-19 08:18:11 +08:00
Version 1.6.0 (2016-01-21)
==========================
Language
--------
* The `#![no_std]` attribute causes a crate to not be linked to the
standard library, but only the [core library][1.6co], as described
in [RFC 1184]. The core library defines common types and traits but
has no platform dependencies whatsoever, and is the basis for Rust
software in environments that cannot support a full port of the
standard library, such as operating systems. Most of the core
library is now stable.
Libraries
---------
* Stabilized APIs:

Release notes for 1.6
2016-01-19 08:18:11 +08:00
* The [core library][1.6co] is stable, as are most of its APIs.
* [The `assert_eq!` macro supports arguments that don't implement
`Sized`][1.6ae], such as arrays. In this way it behaves more like
`assert!`.
* Several timer functions that take duration in milliseconds [are
deprecated in favor of those that take `Duration`][1.6ms]. These
include `Condvar::wait_timeout_ms`, `thread::sleep_ms`, and
`thread::park_timeout_ms`.
* The algorithm by which `Vec` reserves additional elements was
[tweaked to not allocate excessive space][1.6a] while still growing
exponentially.
* `From` conversions are [implemented from integers to floats][1.6f]
in cases where the conversion is lossless. Thus they are not
implemented for 32-bit ints to `f32`, nor for 64-bit ints to `f32`
or `f64`. They are also not implemented for `isize` and `usize`
because the implementations would be platform-specific. `From` is
also implemented from `f32` to `f64`.
* `From<&Path>` and `From<PathBuf>` are implemented for `Cow<Path>`.
* `From<T>` is implemented for `Box<T>`, `Rc<T>` and `Arc<T>`.
* `IntoIterator` is implemented for `&PathBuf` and `&Path`.
* [`BinaryHeap` was refactored][1.6bh] for modest performance
improvements.
* Sorting slices that are already sorted [is 50% faster in some
cases][1.6s].
Cargo
-----
* Cargo will look in `$CARGO_HOME/bin` for subcommands [by default][1.6c].
* Cargo build scripts can specify their dependencies by emitting the
[`rerun-if-changed`][1.6rr] key.
* crates.io will reject publication of crates with dependencies that
have a wildcard version constraint. Crates with wildcard
dependencies were seen to cause a variety of problems, as described
in [RFC 1241]. Since 1.5 publication of such crates has emitted a
warning.
* `cargo clean` [accepts a `--release` flag][1.6cc] to clean the
release folder. A variety of artifacts that Cargo failed to clean
are now correctly deleted.
Misc
----
* The `unreachable_code` lint [warns when a function call's argument
diverges][1.6dv].
* The parser indicates [failures that may be caused by
confusingly-similar Unicode characters][1.6uc]
* Certain macro errors [are reported at definition time][1.6m], not
expansion.
Compatibility Notes
-------------------
* The compiler no longer makes use of the [`RUST_PATH`][1.6rp]
environment variable when locating crates. This was a pre-cargo
feature for integrating with the package manager that was
accidentally never removed.
* [A number of bugs were fixed in the privacy checker][1.6p] that
could cause previously-accepted code to break.
* [Modules and unit/tuple structs may not share the same name][1.6ts].
* [Bugs in pattern matching unit structs were fixed][1.6us]. The tuple
struct pattern syntax (`Foo(..)`) can no longer be used to match
unit structs. This is a warning now, but will become an error in
future releases. Patterns that share the same name as a const are
now an error.
* A bug was fixed that causes [rustc not to apply default type
parameters][1.6xc] when resolving certain method implementations of
traits defined in other crates.

Update RELEASES.md for 1.5
2015-12-04 11:37:30 +08:00
Version 1.5.0 (2015-12-10)
==========================
* ~700 changes, numerous bugfixes
Highlights
----------
* Stabilized APIs:
[`BinaryHeap::from`], [`BinaryHeap::into_sorted_vec`],
[`BinaryHeap::into_vec`], [`Condvar::wait_timeout`],
[`FileTypeExt::is_block_device`], [`FileTypeExt::is_char_device`],
[`FileTypeExt::is_fifo`], [`FileTypeExt::is_socket`],
[`FileTypeExt`], [`Formatter::alternate`], [`Formatter::fill`],
[`Formatter::precision`], [`Formatter::sign_aware_zero_pad`],
[`Formatter::sign_minus`], [`Formatter::sign_plus`],
[`Formatter::width`], [`Iterator::cmp`], [`Iterator::eq`],
[`Iterator::ge`], [`Iterator::gt`], [`Iterator::le`],
[`Iterator::lt`], [`Iterator::ne`], [`Iterator::partial_cmp`],
[`Path::canonicalize`], [`Path::exists`], [`Path::is_dir`],
[`Path::is_file`], [`Path::metadata`], [`Path::read_dir`],
[`Path::read_link`], [`Path::symlink_metadata`],
[`Utf8Error::valid_up_to`], [`Vec::resize`],
[`VecDeque::as_mut_slices`], [`VecDeque::as_slices`],
[`VecDeque::insert`], [`VecDeque::shrink_to_fit`],
[`VecDeque::swap_remove_back`], [`VecDeque::swap_remove_front`],
[`slice::split_first_mut`], [`slice::split_first`],
[`slice::split_last_mut`], [`slice::split_last`],
[`char::from_u32_unchecked`], [`fs::canonicalize`],
[`str::MatchIndices`], [`str::RMatchIndices`],
[`str::match_indices`], [`str::rmatch_indices`],
[`str::slice_mut_unchecked`], [`string::ParseError`].
* Rust applications hosted on crates.io can be installed locally to
`~/.cargo/bin` with the [`cargo install`] command. Among other
things this makes it easier to augment Cargo with new subcommands:
when a binary named e.g. `cargo-foo` is found in `$PATH` it can be
invoked as `cargo foo`.
* Crates with wildcard (`*`) dependencies will [emit warnings when
published][1.5w]. In 1.6 it will no longer be possible to publish
crates with wildcard dependencies.
Breaking Changes
----------------
* The rules determining when a particular lifetime must outlive
a particular value (known as '[dropck]') have been [modified
to not rely on parametricity][1.5p].
* [Implementations of `AsRef` and `AsMut` were added to `Box`, `Rc`,
and `Arc`][1.5a]. Because these smart pointer types implement
`Deref`, this causes breakage in cases where the interior type
contains methods of the same name.
* [Correct a bug in Rc/Arc][1.5c] that caused [dropck] to be unaware
that they could drop their content. Soundness fix.
* All method invocations are [properly checked][1.5wf1] for
[well-formedness][1.5wf2]. Soundness fix.
* Traits whose supertraits contain `Self` are [not object
safe][1.5o]. Soundness fix.
* Target specifications support a [`no_default_libraries`][1.5nd]
setting that controls whether `-nodefaultlibs` is passed to the
linker, and in turn the `is_like_windows` setting no longer affects
the `-nodefaultlibs` flag.
* `#[derive(Show)]`, long-deprecated, [has been removed][1.5ds].
* The `#[inline]` and `#[repr]` attributes [can only appear
in valid locations][1.5at].
* Native libraries linked from the local crate are [passed to
the linker before native libraries from upstream crates][1.5nl].
* Two rarely-used attributes, `#[no_debug]` and
`#[omit_gdb_pretty_printer_section]` [are feature gated][1.5fg].
* Negation of unsigned integers, which has been a warning for
several releases, [is now behind a feature gate and will
generate errors][1.5nu].
* The parser accidentally accepted visibility modifiers on
enum variants, a bug [which has been fixed][1.5ev].
* [A bug was fixed that allowed `use` statements to import unstable
features][1.5use].
Language
--------
* When evaluating expressions at compile-time that are not
compile-time constants (const-evaluating expressions in non-const
contexts), incorrect code such as overlong bitshifts and arithmetic
overflow will [generate a warning instead of an error][1.5ce],
delaying the error until runtime. This will allow the
const-evaluator to be expanded in the future backwards-compatibly.
* The `improper_ctypes` lint [no longer warns about using `isize` and
`usize` in FFI][1.5ict].
Libraries
---------
* `Arc<T>` and `Rc<T>` are [covariant with respect to `T` instead of
invariant][1.5c].
* `Default` is [implemented for mutable slices][1.5d].
* `FromStr` is [implemented for `SockAddrV4` and `SockAddrV6`][1.5s].
* There are now `From` conversions [between floating point
types][1.5f] where the conversions are lossless.

* There are now `From` conversions [between integer types][1.5i] where
Update RELEASES.md for 1.5
2015-12-04 11:37:30 +08:00
the conversions are lossless.
* [`fs::Metadata` implements `Clone`][1.5fs].
* The `parse` method [accepts a leading "+" when parsing
integers][1.5pi].
* [`AsMut` is implemented for `Vec`][1.5am].
* The `clone_from` implementations for `String` and `BinaryHeap` [have
been optimized][1.5cf] and no longer rely on the default impl.
* The `extern "Rust"`, `extern "C"`, `unsafe extern "Rust"` and
`unsafe extern "C"` function types now [implement `Clone`,
`PartialEq`, `Eq`, `PartialOrd`, `Ord`, `Hash`, `fmt::Pointer`, and
`fmt::Debug` for up to 12 arguments][1.5fp].
* [Dropping `Vec`s is much faster in unoptimized builds when the
element types don't implement `Drop`][1.5dv].
* A bug that caused in incorrect behavior when [combining `VecDeque`
with zero-sized types][1.5vdz] was resolved.
* [`PartialOrd` for slices is faster][1.5po].
Miscellaneous
-------------
* [Crate metadata size was reduced by 20%][1.5md].
* [Improvements to code generation reduced the size of libcore by 3.3
MB and rustc's memory usage by 18MB][1.5m].
* [Improvements to deref translation increased performance in
unoptimized builds][1.5dr].
* Various errors in trait resolution [are deduplicated to only be
reported once][1.5te].
* Rust has preliminary [support for rumprun kernels][1.5rr].
* Rust has preliminary [support for NetBSD on amd64][1.5na].

Version 1.4.0 (2015-10-29)
Update RELEASES.md for 1.5
2015-12-04 11:37:30 +08:00
==========================
1.4 release notes
2015-10-28 07:25:33 +08:00
* ~1200 changes, numerous bugfixes
Highlights
----------
* Windows builds targeting the 64-bit MSVC ABI and linker (instead of
GNU) are now supported and recommended for use.
Breaking Changes
----------------
* [Several changes have been made to fix type soundness and improve
the behavior of associated types][sound]. See [RFC 1214]. Although
we have mostly introduced these changes as warnings this release, to
become errors next release, there are still some scenarios that will
see immediate breakage.
* [The `str::lines` and `BufRead::lines` iterators treat `\r\n` as
line breaks in addition to `\n`][crlf].
* [Loans of `'static` lifetime extend to the end of a function][stat].
Address release notes feedback
2015-10-30 02:36:56 +08:00
* [`str::parse` no longer introduces avoidable rounding error when
parsing floating point numbers. Together with earlier changes to
float formatting/output, "round trips" like f.to_string().parse()
now preserve the value of f exactly. Additionally, leading plus
signs are now accepted][fp3].
1.4 release notes
2015-10-28 07:25:33 +08:00
Language
--------
* `use` statements that import multiple items [can now rename
them][i], as in `use foo::{bar as kitten, baz as puppy}`.
* [Binops work correctly on fat pointers][binfat].
* `pub extern crate`, which does not behave as expected, [issues a
warning][pec] until a better solution is found.
Libraries
---------
* [Many APIs were stabilized][stab]: `<Box<str>>::into_string`,
[`Arc::downgrade`], [`Arc::get_mut`], [`Arc::make_mut`],

`Result::as_mut_slice`, `Result::as_slice`, `f32::from_str_radix`,
`f64::from_str_radix`.
* [Reverse-searching strings is faster with the 'two-way'
algorithm][s].
* [`std::io::copy` allows `?Sized` arguments][cc].
* The `Windows`, `Chunks`, and `ChunksMut` iterators over slices all
[override `count`, `nth` and `last` with an O(1)
implementation][it].
* [`Default` is implemented for arrays up to `[T; 32]`][d].
* [`IntoRawFd` has been added to the Unix-specific prelude,
`IntoRawSocket` and `IntoRawHandle` to the Windows-specific
prelude][pr].
* [`Extend<String>` and `FromIterator<String` are both implemented for
`String`][es].

1.4 release notes
2015-10-28 07:25:33 +08:00
* [Function pointers implement traits for up to 12 parameters][fp2].
Miscellaneous
-------------
* The compiler [no longer uses the 'morestack' feature to prevent
stack overflow][mm]. Instead it uses guard pages and stack
probes (though stack probes are not yet implemented on any platform
but Windows).
* [The compiler matches traits faster when projections are involved][p].
* The 'improper_ctypes' lint [no longer warns about use of `isize` and
`usize`][ffi].
* [Cargo now displays useful information about what its doing during
`cargo update`][cu].

Version 1.3.0 (2015-09-17)
1.3 release notes
2015-08-20 05:16:26 +08:00
==============================
* ~900 changes, numerous bugfixes
Highlights
----------
* The [new object lifetime defaults][nold] have been [turned
on][nold2] after a cycle of warnings about the change. Now types
like `&'a Box<Trait>` (or `&'a Rc<Trait>`, etc) will change from
being interpreted as `&'a Box<Trait+'a>` to `&'a
Box<Trait+'static>`.
* [The Rustonomicon][nom] is a new book in the official documentation
that dives into writing unsafe Rust.
* The [`Duration`] API, [has been stabilized][ds]. This basic unit of
timekeeping is employed by other std APIs, as well as out-of-tree
time crates.
Breaking Changes
----------------
* The [new object lifetime defaults][nold] have been [turned
on][nold2] after a cycle of warnings about the change.
* There is a known [regression][lr] in how object lifetime elision is
interpreted, the proper solution for which is undetermined.
* The `#[prelude_import]` attribute, an internal implementation
detail, was accidentally stabilized previously. [It has been put
behind the `prelude_import` feature gate][pi]. This change is
believed to break no existing code.
* The behavior of [`size_of_val`][dst1] and [`align_of_val`][dst2] is
[more sane for dynamically sized types][dst3]. Code that relied on
the previous behavior is thought to be broken.
* The `dropck` rules, which checks that destructors can't access
destroyed values, [have been updated][dropck] to match the
[RFC][dropckrfc]. This fixes some soundness holes, and as such will
cause some previously-compiling code to no longer build.
Language
--------
* The [new object lifetime defaults][nold] have been [turned
on][nold2] after a cycle of warnings about the change.
* Semicolons may [now follow types and paths in
macros](https://github.com/rust-lang/rust/pull/27000).
* The behavior of [`size_of_val`][dst1] and [`align_of_val`][dst2] is
[more sane for dynamically sized types][dst3]. Code that relied on
the previous behavior is not known to exist, and suspected to be
broken.
* `'static` variables [may now be recursive][st].
* `ref` bindings choose between [`Deref`] and [`DerefMut`]
implementations correctly.
* The `dropck` rules, which checks that destructors can't access
destroyed values, [have been updated][dropck] to match the
[RFC][dropckrfc].
Libraries
---------
* The [`Duration`] API, [has been stabilized][ds], as well as the
`std::time` module, which presently contains only `Duration`.
* `Box<str>` and `Box<[T]>` both implement `Clone`.
* The owned C string, [`CString`], implements [`Borrow`] and the
borrowed C string, [`CStr`], implements [`ToOwned`]. The two of
these allow C strings to be borrowed and cloned in generic code.
* [`CStr`] implements [`Debug`].
* [`AtomicPtr`] implements [`Debug`].
* [`Error`] trait objects [can be downcast to their concrete types][e]
in many common configurations, using the [`is`], [`downcast`],
[`downcast_ref`] and [`downcast_mut`] methods, similarly to the
[`Any`] trait.
* Searching for substrings now [employs the two-way algorithm][search]
instead of doing a naive search. This gives major speedups to a
number of methods, including [`contains`][sc], [`find`][sf],
[`rfind`][srf], [`split`][ss]. [`starts_with`][ssw] and
[`ends_with`][sew] are also faster.
* The performance of `PartialEq` for slices is [much faster][ps].
* The [`Hash`] trait offers the default method, [`hash_slice`], which
is overridden and optimized by the implementations for scalars.
* The [`Hasher`] trait now has a number of specialized `write_*`
methods for primitive types, for efficiency.
* The I/O-specific error type, [`std::io::Error`][ie], gained a set of
methods for accessing the 'inner error', if any: [`get_ref`][iegr],
[`get_mut`][iegm], [`into_inner`][ieii]. As well, the implementation
of [`std::error::Error::cause`][iec] also delegates to the inner
error.
* [`process::Child`][pc] gained the [`id`] method, which returns a
`u32` representing the platform-specific process identifier.
* The [`connect`] method on slices is deprecated, replaced by the new
[`join`] method (note that both of these are on the *unstable*
[`SliceConcatExt`] trait, but through the magic of the prelude are
available to stable code anyway).
* The [`Div`] operator is implemented for [`Wrapping`] types.
* [`DerefMut` is implemented for `String`][dms].
* Performance of SipHash (the default hasher for `HashMap`) is
[better for long data][sh].
* [`AtomicPtr`] implements [`Send`].
* The [`read_to_end`] implementations for [`Stdin`] and [`File`]
fix some typos
2017-11-21 22:33:45 +08:00
are now [specialized to use uninitialized buffers for increased
1.3 release notes
2015-08-20 05:16:26 +08:00
performance][rte].
* Lifetime parameters of foreign functions [are now resolved
properly][f].
Misc
----
* Rust can now, with some coercion, [produce programs that run on
Windows XP][xp], though XP is not considered a supported platform.
* Porting Rust on Windows from the GNU toolchain to MSVC continues
([1][win1], [2][win2], [3][win3], [4][win4]). It is still not
recommended for use in 1.3, though should be fully-functional
in the [64-bit 1.4 beta][b14].
* On Fedora-based systems installation will [properly configure the
dynamic linker][fl].
* The compiler gained many new extended error descriptions, which can
be accessed with the `--explain` flag.
* The `dropck` pass, which checks that destructors can't access
destroyed values, [has been rewritten][dropck]. This fixes some
soundness holes, and as such will cause some previously-compiling
code to no longer build.
* `rustc` now uses [LLVM to write archive files where possible][ar].
Eventually this will eliminate the compiler's dependency on the ar
utility.
* Rust has [preliminary support for i686 FreeBSD][fb] (it has long
supported FreeBSD on x86_64).
* The [`unused_mut`][lum], [`unconditional_recursion`][lur],
[`improper_ctypes`][lic], and [`negate_unsigned`][lnu] lints are
more strict.
* If landing pads are disabled (with `-Z no-landing-pads`), [`panic!`
will kill the process instead of leaking][nlp].

Highlights
----------
Update RELEASES.md for 1.2
2015-07-10 05:34:30 +08:00
* [Dynamically-sized-type coercions][dst] allow smart pointer types
like `Rc` to contain types without a fixed size, arrays and trait
objects, finally enabling use of `Rc<[T]>` and completing the
implementation of DST.
* [Parallel codegen][parcodegen] is now working again, which can
substantially speed up large builds in debug mode; It also gets
another ~33% speedup when bootstrapping on a 4 core machine (using 8
jobs). It's not enabled by default, but will be "in the near
future". It can be activated with the `-C codegen-units=N` flag to
`rustc`.

* This is the first release with [experimental support for linking
with the MSVC linker and lib C on Windows (instead of using the GNU
variants via MinGW)][win]. It is yet recommended only for the most

2015-07-10 05:34:30 +08:00
Breaking Changes
----------------
* The [`to_uppercase`] and [`to_lowercase`] methods on `char` now do
unicode case mapping, which is a previously-planned change in
behavior and considered a bugfix.
* [`mem::align_of`] now specifies [the *minimum alignment* for
T][align], which is usually the alignment programs are interested
in, and the same value reported by clang's
`alignof`. [`mem::min_align_of`] is deprecated. This is not known to
break real code.
Mention that removal of `#[packed]` was a breaking change in 1.2
2015-07-15 01:32:23 +08:00
* [The `#[packed]` attribute is no longer silently accepted by the
compiler][packed]. This attribute did nothing and code that
mentioned it likely did not work as intended.
More 1.2 relnotes
2015-07-31 05:27:54 +08:00
* Associated type defaults are [now behind the
`associated_type_defaults` feature gate][ad]. In 1.1 associated type
defaults *did not work*, but could be mentioned syntactically. As
such this breakage has minimal impact.
Update RELEASES.md for 1.2
2015-07-10 05:34:30 +08:00
Language
--------
* Patterns with `ref mut` now correctly invoke [`DerefMut`] when
releases.md: fix 2 typos

matching against dereferenceable values.
Update RELEASES.md for 1.2
2015-07-10 05:34:30 +08:00
Libraries
---------
* The [`Extend`] trait, which grows a collection from an iterator, is
implemented over iterators of references, for `String`, `Vec`,
`LinkedList`, `VecDeque`, `EnumSet`, `BinaryHeap`, `VecMap`,
`BTreeSet` and `BTreeMap`. [RFC][extend-rfc].
* The [`iter::once`] function returns an iterator that yields a single
More 1.2 relnotes
2015-07-31 05:27:54 +08:00
element, and [`iter::empty`] returns an iterator that yields no
Update RELEASES.md for 1.2
2015-07-10 05:34:30 +08:00
elements.
* The [`matches`] and [`rmatches`] methods on `str` return iterators
over substring matches.
More 1.2 relnotes
2015-07-31 05:27:54 +08:00
* [`Cell`] and [`RefCell`] both implement `Eq`.
Update RELEASES.md for 1.2
2015-07-10 05:34:30 +08:00
* A number of methods for wrapping arithmetic are added to the
integral types, [`wrapping_div`], [`wrapping_rem`],
[`wrapping_neg`], [`wrapping_shl`], [`wrapping_shr`]. These are in
addition to the existing [`wrapping_add`], [`wrapping_sub`], and
[`wrapping_mul`] methods, and alternatives to the [`Wrapping`]
type.. It is illegal for the default arithmetic operations in Rust
to overflow; the desire to wrap must be explicit.
* The `{:#?}` formatting specifier [displays the alternate,
pretty-printed][debugfmt] form of the `Debug` formatter. This
feature was actually introduced prior to 1.0 with little
fanfare.
* [`fmt::Formatter`] implements [`fmt::Write`], a `fmt`-specific trait
for writing data to formatted strings, similar to [`io::Write`].
* [`fmt::Formatter`] adds 'debug builder' methods, [`debug_struct`],
[`debug_tuple`], [`debug_list`], [`debug_set`], [`debug_map`]. These
are used by code generators to emit implementations of [`Debug`].
* `str` has new [`to_uppercase`][strup] and [`to_lowercase`][strlow]
methods that convert case, following Unicode case mapping.
small fix in RELEASES this grammar isn't correct
2015-08-04 04:19:21 +08:00
* It is now easier to handle poisoned locks. The [`PoisonError`]
Update RELEASES.md for 1.2
2015-07-10 05:34:30 +08:00
type, returned by failing lock operations, exposes `into_inner`,
`get_ref`, and `get_mut`, which all give access to the inner lock
guard, and allow the poisoned lock to continue to operate. The
`is_poisoned` method of [`RwLock`] and [`Mutex`] can poll for a
poisoned lock without attempting to take the lock.
* On Unix the [`FromRawFd`] trait is implemented for [`Stdio`], and
[`AsRawFd`] for [`ChildStdin`], [`ChildStdout`], [`ChildStderr`].
On Windows the `FromRawHandle` trait is implemented for `Stdio`,
and `AsRawHandle` for `ChildStdin`, `ChildStdout`,
`ChildStderr`.
* [`io::ErrorKind`] has a new variant, `InvalidData`, which indicates
malformed input.

Update RELEASES.md for 1.1

=========================
std: Stabilize a number of new fs features This commit stabilizes the following APIs, slating them all to be cherry-picked into the 1.1 release. * fs::FileType (and transitively the derived trait implementations) * fs::Metadata::file_type * fs::FileType::is_dir * fs::FileType::is_file * fs::FileType::is_symlink * fs::DirEntry::metadata * fs::DirEntry::file_type * fs::DirEntry::file_name * fs::set_permissions * fs::symlink_metadata * os::raw::{self, *} * os::{android, bitrig, linux, ...}::raw::{self, *} * os::{android, bitrig, linux, ...}::fs::MetadataExt * os::{android, bitrig, linux, ...}::fs::MetadataExt::as_raw_stat * os::unix::fs::PermissionsExt * os::unix::fs::PermissionsExt::mode * os::unix::fs::PermissionsExt::set_mode * os::unix::fs::PermissionsExt::from_mode * os::unix::fs::OpenOptionsExt * os::unix::fs::OpenOptionsExt::mode * os::unix::fs::DirEntryExt * os::unix::fs::DirEntryExt::ino * os::windows::fs::MetadataExt * os::windows::fs::MetadataExt::file_attributes * os::windows::fs::MetadataExt::creation_time * os::windows::fs::MetadataExt::last_access_time * os::windows::fs::MetadataExt::last_write_time * os::windows::fs::MetadataExt::file_size The `os::unix::fs::Metadata` structure was also removed entirely, moving all of its associated methods into the `os::unix::fs::MetadataExt` trait instead. The methods are all marked as `#[stable]` still. As some minor cleanup, some deprecated and unstable fs apis were also removed: * File::path * Metadata::accessed * Metadata::modified Features that were explicitly left unstable include: * fs::WalkDir - the semantics of this were not considered in the recent fs expansion RFC. * fs::DirBuilder - it's still not 100% clear if the naming is right here and if the set of functionality exposed is appropriate. * fs::canonicalize - the implementation on Windows here is specifically in question as it always returns a verbatim path. Additionally the Unix implementation is susceptible to buffer overflows on long paths unfortunately. * fs::PathExt - as this is just a convenience trait, it is not stabilized at this time. * fs::set_file_times - this funciton is still waiting on a time abstraction.

Correct typos and remove unused references from RELEASES.md I found some typos in the upcoming 1.1 release note. I corrected them, but I wanted to go further. So I wrote a script that checks the integrity of the Markdown references, and ran it against `RELEASES.md`. This commit fixes some trivial cases, but also removes the following "unused" references: - [`Iterator::cloned`](http://doc.rust-lang.org/nightly/core/iter/trait.Iterator.html#method.cloned) - [`thread::scoped`](http://static.rust-lang.org/doc/master/std/thread/fn.scoped.html) - [`Debug` improvements](https://github.com/rust-lang/rfcs/blob/master/text/0640-debug-improvements.md) - [Rebalancing coherence.](https://github.com/rust-lang/rfcs/pull/1023) However, I think there's a possibility that these features might need to get descriptions as well. How do you feel about it?

functionality exposed:
* `DirEntry` now supports optimizations like `file_type` and `metadata` which
don't incur a syscall on some platforms.
* A `symlink_metadata` function has been added.
* The `fs::Metadata` structure now lowers to its OS counterpart, providing
access to all underlying information.
relnotes: Fix error index link.
2015-06-25 21:29:09 +08:00
* The compiler now contains extended explanations of many errors. When an error
with an explanation occurs the compiler suggests using the `--explain` flag
to read the explanation. Error explanations are also [available online][err-index].

2015-06-11 09:59:55 +08:00
* Thanks to multiple [improvements][sk] to [type checking][pre], as

32%.

and `AsRawHandle`. These are implemented for `File`, `TcpStream`,
`TcpListener`, and `UpdSocket`. Further implementations for
`std::process` will be stabilized later.
* On Unix, [`std::os::unix::symlink`] creates symlinks. On
Windows, symlinks can be created with
`std::os::windows::symlink_dir` and
`std::os::windows::symlink_file`.
* The `mpsc::Receiver` type can now be converted into an iterator with
`into_iter` on the [`IntoIterator`] trait.
* `Ipv4Addr` can be created from `u32` with the `From<u32>`
implementation of the [`From`] trait.
* The `Debug` implementation for `RangeFull` [creates output that is
more consistent with other implementations][rf].
* [`Debug` is implemented for `File`][file].
* The `Default` implementation for `Arc` [no longer requires `Sync +
Send`][arc].
* [The `Iterator` methods `count`, `nth`, and `last` have been
overridden for slices to have O(1) performance instead of O(n)][si].
* Incorrect handling of paths on Windows has been improved in both the
compiler and the standard library.
* [`AtomicPtr` gained a `Default` implementation][ap].
* In accordance with Rust's policy on arithmetic overflow `abs` now
[panics on overflow when debug assertions are enabled][abs].
* The [`Cloned`] iterator, which was accidentally left unstable for
1.0 [has been stabilized][c].
* The [`Incoming`] iterator, which iterates over incoming TCP
connections, and which was accidentally unnamable in 1.0, [is now
properly exported][inc].
* [`BinaryHeap`] no longer corrupts itself [when functions called by
`sift_up` or `sift_down` panic][bh].
* The [`split_off`] method of `LinkedList` [no longer corrupts
the list in certain scenarios][ll].
Misc
----
* Type checking performance [has improved notably][sk] with
[multiple improvements][pre].
* The compiler [suggests code changes][ch] for more errors.
* rustc and it's build system have experimental support for [building
toolchains against MUSL][m] instead of glibc on Linux.
* The compiler defines the `target_env` cfg value, which is used for
distinguishing toolchains that are otherwise for the same
platform. Presently this is set to `gnu` for common GNU Linux
targets and for MinGW targets, and `musl` for MUSL Linux targets.
* The [`cargo rustc`][crc] command invokes a build with custom flags
to rustc.
* [Android executables are always position independent][pie].
* [The `drop_with_repr_extern` lint warns about mixing `repr(C)`
with `Drop`][drop].

* The vast majority of the standard library is now `#[stable]`. It is
no longer possible to use unstable features with a stable build of
the compiler.
* Many popular crates on [crates.io] now work on the stable release
channel.
* Arithmetic on basic integer types now [checks for overflow in debug
builds][overflow].

* Digits of binary and octal literals are [lexed more eagerly][lex] to
improve error messages and macro behavior. For example, `0b1234` is
now lexed as `0b1234` instead of two tokens, `0b1` and `234`.

* Trait bounds [are always invariant][inv], eliminating the need for

2015-05-07 04:23:33 +08:00
the `PhantomFn` and `MarkerTrait` lang items, which have been
removed.
* ["-" is no longer a valid character in crate names][cr], the `extern crate
"foo" as bar` syntax has been replaced with `extern crate foo as
bar`, and Cargo now automatically translates "-" in *package* names
to underscore for the crate name.
* [Lifetime shadowing is an error][lt].
* [`Send` no longer implies `'static`][send-rfc].
* [UFCS now supports trait-less associated paths][moar-ufcs] like
`MyType::default()`.
* Primitive types [now have inherent methods][prim-inherent],
obviating the need for extension traits like `SliceExt`.
* Methods with `Self: Sized` in their `where` clause are [considered
object-safe][self-sized], allowing many extension traits like
`IteratorExt` to be merged into the traits they extended.
* You can now [refer to associated types][assoc-where] whose
corresponding trait bounds appear only in a `where` clause.
* The final bits of [OIBIT landed][oibit-final], meaning that traits
like `Send` and `Sync` are now library-defined.
* A [Reflect trait][reflect] was introduced, which means that
downcasting via the `Any` trait is effectively limited to concrete
types. This helps retain the potentially-important "parametricity"
property: generic code cannot behave differently for different type
arguments except in minor ways.
* The `unsafe_destructor` feature is now deprecated in favor of the
[new `dropck`][dropck]. This change is a major reduction in unsafe
code.

* The `thread_local` module [has been renamed to `std::thread`][th].
* The methods of `IteratorExt` [have been moved to the `Iterator`
trait itself][ie].
* Several traits that implement Rust's conventions for type
conversions, `AsMut`, `AsRef`, `From`, and `Into` have been
[centralized in the `std::convert` module][con].
* The `FromError` trait [was removed in favor of `From`][fe].
* The basic sleep function [has moved to
`std::thread::sleep_ms`][slp].
* The `splitn` function now takes an `n` parameter that represents the
number of items yielded by the returned iterator [instead of the
number of 'splits'][spl].
* [On Unix, all file descriptors are `CLOEXEC` by default][clo].
* [Derived implementations of `PartialOrd` now order enums according
to their explicitly-assigned discriminants][po].
* [Methods for searching strings are generic over `Pattern`s][pat],
implemented presently by `&char`, `&str`, `FnMut(char) -> bool` and
some others.
* [In method resolution, object methods are resolved before inherent
methods][meth].
* [`String::from_str` has been deprecated in favor of the `From` impl,
`String::from`][sf].
* [`io::Error` implements `Sync`][ios].
* [The `words` method on `&str` has been replaced with
`split_whitespace`][sw], to avoid answering the tricky question, 'what is
a word?'
* The new path and IO modules are complete and `#[stable]`. This
was the major library focus for this cycle.
* The path API was [revised][path-normalize] to normalize `.`,
adjusting the tradeoffs in favor of the most common usage.
* A large number of remaining APIs in `std` were also stabilized
during this cycle; about 75% of the non-deprecated API surface
is now stable.
* The new [string pattern API][string-pattern] landed, which makes
the string slice API much more internally consistent and flexible.
* A new set of [generic conversion traits][conversion] replaced
many existing ad hoc traits.
* Generic numeric traits were [completely removed][num-traits]. This
was made possible thanks to inherent methods for primitive types,
and the removal gives maximal flexibility for designing a numeric
hierarchy in the future.
* The `Fn` traits are now related via [inheritance][fn-inherit]
and provide ergonomic [blanket implementations][fn-blanket].
* The `Index` and `IndexMut` traits were changed to
[take the index by value][index-value], enabling code like
`hash_map["string"]` to work.
* `Copy` now [inherits][copy-clone] from `Clone`, meaning that all
`Copy` data is known to be `Clone` as well.

the underlying platform. The old `io` module remains temporarily

Fix a few typos in the releases
2015-05-20 08:34:14 +08:00
* The standard library now [participates in feature gating][feat],
Update AUTHORS.txt and RELEASES.md
2015-02-19 09:02:34 +08:00
so use of unstable libraries now requires a `#![feature(...)]`
attribute. The impact of this change is [described on the
forum][feat-forum]. [RFC][feat-rfc].
* Language
* `for` loops [now operate on the `IntoIterator` trait][into],
which eliminates the need to call `.iter()`, etc. to iterate
over collections. There are some new subtleties to remember
though regarding what sort of iterators various types yield, in
particular that `for foo in bar { }` yields values from a move
iterator, destroying the original collection. [RFC][into-rfc].
* Objects now have [default lifetime bounds][obj], so you don't
have to write `Box<Trait+'static>` when you don't care about
storing references. [RFC][obj-rfc].
* In types that implement `Drop`, [lifetimes must outlive the
value][drop]. This will soon make it possible to safely
implement `Drop` for types where `#[unsafe_destructor]` is now
required. Read the [gorgeous RFC][drop-rfc] for details.
* The fully qualified <T as Trait>::X syntax lets you set the Self
type for a trait method or associated type. [RFC][ufcs-rfc].
* References to types that implement `Deref<U>` now [automatically
coerce to references][deref] to the dereferenced type `U`,
e.g. `&T where T: Deref<U>` automatically coerces to `&U`. This
should eliminate many unsightly uses of `&*`, as when converting
from references to vectors into references to
slices. [RFC][deref-rfc].
* The explicit [closure kind syntax][close] (`|&:|`, `|&mut:|`,
`|:|`) is obsolete and closure kind is inferred from context.
* [`Self` is a keyword][Self].
* Libraries
* The `Show` and `String` formatting traits [have been
renamed][fmt] to `Debug` and `Display` to more clearly reflect
their related purposes. Automatically getting a string
conversion to use with `format!("{:?}", something_to_debug)` is
now written `#[derive(Debug)]`.
* Abstract [OS-specific string types][osstr], `std::ff::{OsString,
OsStr}`, provide strings in platform-specific encodings for easier
interop with system APIs. [RFC][osstr-rfc].
Fix frow_raw/from_raw typo
2015-02-21 20:14:17 +08:00
* The `boxed::into_raw` and `Box::from_raw` functions [convert

2015-02-19 09:02:34 +08:00
between `Box<T>` and `*mut T`][boxraw], a common pattern for
creating raw pointers.
* Tooling
* Certain long error messages of the form 'expected foo found bar'
are now [split neatly across multiple
lines][multiline]. Examples in the PR.
* On Unix Rust can be [uninstalled][un] by running
`/usr/local/lib/rustlib/uninstall.sh`.
* The `#[rustc_on_unimplemented]` attribute, requiring the
'on_unimplemented' feature, lets rustc [display custom error
messages when a trait is expected to be implemented for a type
but is not][onun].
* Misc
* Rust is tested against a [LALR grammar][lalr], which parses
almost all the Rust files that rustc does.

* Nearly 50% of the public API surface of the standard library has

been declared 'stable'. Those interfaces are unlikely to change
before 1.0.
Add int discussion, tweak wording
2015-01-07 12:53:55 +08:00
* The long-running debate over integer types has been
[settled][ints]: Rust will ship with types named `isize` and
`usize`, rather than `int` and `uint`, for pointer-sized
integers. Guidelines will be rolled out during the alpha cycle.
1.0.0-alpha release notes
2015-01-06 15:41:12 +08:00
* Most crates that are not `std` have been moved out of the Rust
distribution into the Cargo ecosystem so they can evolve
separately and don't need to be stabilized as quickly, including
'time', 'getopts', 'num', 'regex', and 'term'.
"The Rust Programming Language" This pulls all of our long-form documentation into a single document, nicknamed "the book" and formally titled "The Rust Programming Language." A few things motivated this change: * People knew of The Guide, but not the individual Guides. This merges them together, helping discoverability. * You can get all of Rust's longform documentation in one place, which is nice. * We now have rustbook in-tree, which can generate this kind of documentation. While its style is basic, the general idea is much better: a table of contents on the left-hand side. * Rather than a almost 10,000-line guide.md, there are now smaller files per section.
2014-12-02 22:20:48 +08:00
* Documentation continues to be expanded with more API coverage, more
examples, and more in-depth explanations. The guides have been
consolidated into [The Rust Programming Language][trpl].

* Closures have been [completely redesigned][unboxed] to be
implemented in terms of traits, can now be used as generic type
bounds and thus monomorphized and inlined, or via an opaque
pointer (boxed) as in the old system. The new system is often
referred to as 'unboxed' closures.

of related types to be defined together and used generically in
powerful ways.

* Enum variants are [namespaced by their type names][enum].

remains valid.

numeric types.
* Rust [no longer has a runtime][rt] of any description, and only
supports OS threads, not green threads.
* At long last, Rust has been overhauled for 'dynamically-sized
types' ([DST]), which integrates 'fat pointers' (object types,
arrays, and `str`) more deeply into the type system, making it
more consistent.
* Rust now has a general [range syntax][range], `i..j`, `i..`, and
`..j` that produce range types and which, when combined with the

notation, `[i..j]`.
* The new range syntax revealed an ambiguity in the fixed-length
array syntax, so now fixed length arrays [are written `[T;
N]`][arrays].
* The `Copy` trait is no longer implemented automatically. Unsafe
pointers no longer implement `Sync` and `Send` so types
containing them don't automatically either. `Sync` and `Send`
are now 'unsafe traits' so one can "forcibly" implement them via
`unsafe impl` if a type confirms to the requirements for them
even though the internals do not (e.g. structs containing unsafe
pointers like `Arc`). These changes are intended to prevent some
footguns and are collectively known as [opt-in built-in

1.0.0-alpha release notes
2015-01-06 15:41:12 +08:00
library types unknown to the compiler).
* Operator traits now take their operands [by value][ops], and
comparison traits can use multidispatch to compare one type
against multiple other types, allowing e.g. `String` to be
compared with `&str`.
* `if let` and `while let` are no longer feature-gated.
* Rust has adopted a more [uniform syntax for escaping unicode
characters][unicode].
* `macro_rules!` [has been declared stable][mac]. Though it is a
flawed system it is sufficiently popular that it must be usable

in ways that will allow other macro systems to be developed in
parallel, and won't otherwise impact the evolution of the
language.
1.0.0-alpha release notes
2015-01-06 15:41:12 +08:00
* The prelude has been [pared back significantly][prelude] such
that it is the minimum necessary to support the most pervasive
code patterns, and through [generalized where clauses][where]
many of the prelude extension traits have been consolidated.
* Rust's rudimentary reflection [has been removed][refl], as it
incurred too much code generation for little benefit.
* [Struct variants][structvars] are no longer feature-gated.
* Trait bounds can be [polymorphic over lifetimes][hrtb]. Also
known as 'higher-ranked trait bounds', this crucially allows
unboxed closures to work.
* Macros invocations surrounded by parens or square brackets and
not terminated by a semicolon are [parsed as
expressions][macros], which makes expressions like `vec![1i32,
2, 3].len()` work as expected.

traits that can be coerced to objects now must be [object
safe][objsafe].

2015-01-06 15:41:12 +08:00
* Automatically deriving traits is now done with `#[derive(...)]`
not `#[deriving(...)]` for [consistency with other naming
conventions][derive].

* Importing the containing module or enum at the same time as
items or variants they contain is [now done with `self` instead
of `mod`][self], as in use `foo::{self, bar}`

* The `box` operator and `box` patterns have been feature-gated
pending a redesign. For now unique boxes should be allocated
like other containers, with `Box::new`.
1.0.0-alpha release notes
2015-01-06 15:41:12 +08:00
* Libraries
* A [series][coll1] of [efforts][coll2] to establish
[conventions][coll3] for collections types has resulted in API
improvements throughout the standard library.
* New [APIs for error handling][err] provide ergonomic interop
between error types, and [new conventions][err-conv] describe
more clearly the recommended error handling strategies in Rust.
* The `fail!` macro has been renamed to [`panic!`][panic] so that
it is easier to discuss failure in the context of error handling
without making clarifications as to whether you are referring to
the 'fail' macro or failure more generally.

* The `Show` formatter, typically implemented with
`#[derive(Show)]` is [now requested with the `{:?}`
specifier][show] and is intended for use by all types, for uses
such as `println!` debugging. The new `String` formatter must be
implemented by hand, uses the `{}` specifier, and is intended
for full-fidelity conversions of things that can logically be
represented as strings.
* Tooling

generation to be configured to support otherwise-unsupported
platforms.
* Rust comes with rust-gdb and rust-lldb scripts that launch their
respective debuggers with Rust-appropriate pretty-printing.

MinGW components currently required to link binaries on that
platform.
* Misc
* Nullable enum optimizations have been extended to more types so
that e.g. `Option<Vec<T>>` and `Option<String>` take up no more
space than the inner types themselves.
* Work has begun on supporting AArch64.

=============================
Update RELEASES.md for 0.12.0
2014-10-03 06:54:43 +08:00
Update per feedback
2014-10-07 03:07:28 +08:00
* ~1900 changes, numerous bugfixes
Update RELEASES.md for 0.12.0
2014-10-03 06:54:43 +08:00
* Highlights
* The introductory documentation (now called The Rust Guide) has
been completely rewritten, as have a number of supplementary
guides.
More relnotes tweaks
2014-10-07 08:30:30 +08:00
* Rust's package manager, Cargo, continues to improve and is
sometimes considered to be quite awesome.
Update RELEASES.md for 0.12.0
2014-10-03 06:54:43 +08:00
* Many API's in `std` have been reviewed and updated for
consistency with the in-development Rust coding
guidelines. The standard library documentation tracks
stabilization progress.
* Minor libraries have been moved out-of-tree to the rust-lang org
on GitHub: uuid, semver, glob, num, hexfloat, fourcc. They can
be installed with Cargo.
* Lifetime elision allows lifetime annotations to be left off of
function declarations in many common scenarios.
* Rust now works on 64-bit Windows.
* Language
* Indexing can be overloaded with the `Index` and `IndexMut`
traits.
* The `if let` construct takes a branch only if the `let` pattern
matches, currently behind the 'if_let' feature gate.
Update per feedback
2014-10-07 03:07:28 +08:00
* 'where clauses', a more flexible syntax for specifying trait
bounds that is more aesthetic, have been added for traits and
free functions. Where clauses will in the future make it
possible to constrain associated types, which would be
impossible with the existing syntax.
* A new slicing syntax (e.g. `[0..4]`) has been introduced behind
the 'slicing_syntax' feature gate, and can be overloaded with
More relnotes tweaks
2014-10-07 08:30:30 +08:00
the `Slice` or `SliceMut` traits.
Update per feedback
2014-10-07 03:07:28 +08:00
* The syntax for matching of sub-slices has been changed to use a
postfix `..` instead of prefix (.e.g. `[a, b, c..]`), for
consistency with other uses of `..` and to future-proof
potential additional uses of the syntax.
* The syntax for matching inclusive ranges in patterns has changed
from `0..3` to `0...4` to be consistent with the exclusive range
syntax for slicing.
* Matching of sub-slices in non-tail positions (e.g. `[a.., b,
c]`) has been put behind the 'advanced_slice_patterns' feature
gate and may be removed in the future.
* Components of tuples and tuple structs can be extracted using
the `value.0` syntax, currently behind the `tuple_indexing`
feature gate.
Update RELEASES.md for 0.12.0
2014-10-03 06:54:43 +08:00
* The `#[crate_id]` attribute is no longer supported; versioning
is handled by the package manager.
Update per feedback
2014-10-07 03:07:28 +08:00
* Renaming crate imports are now written `extern crate foo as bar`
instead of `extern crate bar = foo`.
* Renaming use statements are now written `use foo as bar` instead
of `use bar = foo`.
* `let` and `match` bindings and argument names in macros are now
hygienic.
Update RELEASES.md for 0.12.0
2014-10-03 06:54:43 +08:00
* The new, more efficient, closure types ('unboxed closures') have
been added under a feature gate, 'unboxed_closures'. These will
soon replace the existing closure types, once higher-ranked
trait lifetimes are added to the language.
Update per feedback
2014-10-07 03:07:28 +08:00
* `move` has been added as a keyword, for indicating closures
that capture by value.
* Mutation and assignment is no longer allowed in pattern guards.
* Generic structs and enums can now have trait bounds.
Update RELEASES.md for 0.12.0
2014-10-03 06:54:43 +08:00
* The `Share` trait is now called `Sync` to free up the term
'shared' to refer to 'shared reference' (the default reference
type.
* Dynamically-sized types have been mostly implemented,
unifying the behavior of fat-pointer types with the rest of the
type system.
* As part of dynamically-sized types, the `Sized` trait has been
introduced, which qualifying types implement by default, and
which type parameters expect by default. To specify that a type
Update per feedback
2014-10-07 03:07:28 +08:00
parameter does not need to be sized, write `<Sized? T>`. Most
Update RELEASES.md for 0.12.0
2014-10-03 06:54:43 +08:00
types are `Sized`, notable exceptions being unsized arrays
(`[T]`) and trait types.
Update per feedback
2014-10-07 03:07:28 +08:00
* Closures can return `!`, as in `|| -> !` or `proc() -> !`.
* Lifetime bounds can now be applied to type parameters and object
types.
* The old, reference counted GC type, `Gc<T>` which was once
denoted by the `@` sigil, has finally been removed. GC will be
revisited in the future.
Update RELEASES.md for 0.12.0
2014-10-03 06:54:43 +08:00
* Libraries
* Library documentation has been improved for a number of modules.
* Bit-vectors, collections::bitv has been modernized.
* The url crate is deprecated in favor of
http://github.com/servo/rust-url, which can be installed with
Cargo.
Update per feedback
2014-10-07 03:07:28 +08:00
* Most I/O stream types can be cloned and subsequently closed from
a different thread.
Update RELEASES.md for 0.12.0
2014-10-03 06:54:43 +08:00
* A `std::time::Duration` type has been added for use in I/O
methods that rely on timers, as well as in the 'time' crate's
`Timespec` arithmetic.
Update per feedback
2014-10-07 03:07:28 +08:00
* The runtime I/O abstraction layer that enabled the green thread
scheduler to do non-thread-blocking I/O has been removed, along
with the libuv-based implementation employed by the green thread
scheduler. This will greatly simplify the future I/O work.
* `collections::btree` has been rewritten to have a more
idiomatic and efficient design.
Update RELEASES.md for 0.12.0
2014-10-03 06:54:43 +08:00
* Tooling
* rustdoc output now indicates the stability levels of API's.
* The `--crate-name` flag can specify the name of the crate
being compiled, like `#[crate_name]`.
Update per feedback
2014-10-07 03:07:28 +08:00
* The `-C metadata` specifies additional metadata to hash into
Update RELEASES.md for 0.12.0
2014-10-03 06:54:43 +08:00
symbol names, and `-C extra-filename` specifies additional

information to put into the output filename, for use by the
package manager for versioning.
Update RELEASES.md for 0.12.0
2014-10-03 06:54:43 +08:00
* debug info generation has continued to improve and should be
more reliable under both gdb and lldb.
* rustc has experimental support for compiling in parallel
using the `-C codegen-units` flag.
* rustc no longer encodes rpath information into binaries by
default.

* ~[T] has been removed from the language. This type is superseded by
the Vec<T> type.
* ~str has been removed from the language. This type is superseded by
the String type.
* ~T has been removed from the language. This type is superseded by the
Box<T> type.
* @T has been removed from the language. This type is superseded by the
standard library's std::gc::Gc<T> type.
* Struct fields are now all private by default.
* Vector indices and shift amounts are both required to be a `uint`
instead of any integral type.
* Byte character, byte string, and raw byte string literals are now all
supported by prefixing the normal literal with a `b`.
* Multiple ABIs are no longer allowed in an ABI string
* The syntax for lifetimes on closures/procedures has been tweaked
slightly: `<'a>|A, B|: 'b + K -> T`
* Floating point modulus has been removed from the language; however it
is still provided by a library implementation.
* Private enum variants are now disallowed.
* The `priv` keyword has been removed from the language.

literal.
* The Box<T> type is no longer implicitly borrowed to &mut T.
* Procedures are now required to not capture borrowed references.
* Libraries
* The standard library is now a "facade" over a number of underlying
libraries. This means that development on the standard library should
fix some typos
2017-11-21 22:33:45 +08:00
be speedier due to smaller crates, as well as a clearer line between
Updated release notes for 0.11.0
2014-06-28 03:46:42 +08:00
all dependencies.
* A new library, libcore, lives under the standard library's facade
which is Rust's "0-assumption" library, suitable for embedded and
kernel development for example.
* A regex crate has been added to the standard distribution. This crate
includes statically compiled regular expressions.

correctly handles many repeated 0-length reads.
* The process-spawning API is now centered around a builder-style
Command struct.

* Many trait inheritance bugs fixed.
* Owned and borrowed trait objects work more reliably.
* `copy` is no longer a keyword. It has been replaced by the `Clone` trait.
Invert --cfg debug to --cfg ndebug Many people will be very confused that their debug! statements aren't working when they first use rust only to learn that they should have been building with `--cfg debug` the entire time. This inverts the meaning of the flag to instead of enabling debug statements, now it disables debug statements. This way the default behavior is a bit more reasonable, and requires less end-user configuration. Furthermore, this turns on debug by default when building the rustc compiler.

* mod.rs is now "blessed". When loading `mod foo;`, rustc will now look
for foo.rs, then foo/mod.rs, and will generate an error when both are
present.
* Strings no longer contain trailing nulls. The new `std::c_str` module
provides new mechanisms for converting to C strings.
* The type of foreign functions is now `extern "C" fn` instead of `*u8'.
* The FFI has been overhauled such that foreign functions are called directly,
instead of through a stack-switching wrapper.
* Calling a foreign function must be done through a Rust function with the
`#[fixed_stack_segment]` attribute.
* The `externfn!` macro can be used to declare both a foreign function and
a `#[fixed_stack_segment]` wrapper at once.
* `pub` and `priv` modifiers on `extern` blocks are no longer parsed.
* `unsafe` is no longer allowed on extern fns - they are all unsafe.
* `priv` is disallowed everywhere except for struct fields and enum variants.
* `&T` (besides `&'static T`) is no longer allowed in `@T`.
* `ref` bindings in irrefutable patterns work correctly now.
* `char` is now prevented from containing invalid code points.

prefixes (default: allow).
* Arithmetic operations have been implemented on the SIMD types in
`std::unstable::simd`.
* Exchange allocation headers were removed, reducing memory usage.
* `format!` implements a completely new, extensible, and higher-performance
string formatting system. It will replace `fmt!`.
* `print!` and `println!` write formatted strings (using the `format!`
extension) to stdout.
* `write!` and `writeln!` write formatted strings (using the `format!`
extension) to the new Writers in `std::rt::io`.
* The library section in which a function or static is placed may
be specified with `#[link_section = "..."]`.
* The `proto!` syntax extension for defining bounded message protocols
was removed.
