(https://github.com/rust-lang/rust/pull/33803)
Cargo
-----
* [Disallow specifying features of transitive deps]
(https://github.com/rust-lang/cargo/pull/2821)
* [Add color support for Windows consoles]
(https://github.com/rust-lang/cargo/pull/2804)
* [Fix `harness = false` on `[lib]` sections]
(https://github.com/rust-lang/cargo/pull/2795)
* [Don't panic when `links` contains a '.']
(https://github.com/rust-lang/cargo/pull/2787)
* [Build scripts can emit warnings]
(https://github.com/rust-lang/cargo/pull/2630),
and `-vv` prints warnings for all crates.
* [Ignore file locks on OS X NFS mounts]
(https://github.com/rust-lang/cargo/pull/2720)
* [Don't warn about `package.metadata` keys]
(https://github.com/rust-lang/cargo/pull/2668).
This provides room for expansion by arbitrary tools.
* [Add support for cdylib crate types]
(https://github.com/rust-lang/cargo/pull/2741)
* [Prevent publishing crates when files are dirty]
(https://github.com/rust-lang/cargo/pull/2781)

Performance
-----------
* [Caching projections speeds up type check dramatically for some
workloads]
(https://github.com/rust-lang/rust/pull/33816)
* [The default `HashMap` hasher is SipHash 1-3 instead of SipHash 2-4]
(https://github.com/rust-lang/rust/pull/33940)
This hasher is faster, but is believed to provide sufficient
protection from collision attacks.
* [Comparison of `Ipv4Addr` is 10x faster]
(https://github.com/rust-lang/rust/pull/33891)
Rustdoc
-------
* [Fix empty implementation section on some module pages]

(https://github.com/rust-lang/rust/pull/34479)
* [Fix search result layout for enum variants and struct fields]
(https://github.com/rust-lang/rust/pull/34477)
* [Fix issues with source links to external crates]
(https://github.com/rust-lang/rust/pull/34387)
* [Fix redirect pages for renamed reexports]
(https://github.com/rust-lang/rust/pull/34245)
Tooling
-------
* [rustc is better at finding the MSVC toolchain]
(https://github.com/rust-lang/rust/pull/34492)
* [When emitting debug info, rustc emits frame pointers for closures,
shims and glue, as it does for all other functions]
(https://github.com/rust-lang/rust/pull/33909)
* [rust-lldb warns about unsupported versions of LLDB]
(https://github.com/rust-lang/rust/pull/34646)
* Many more errors have been given error codes and extended
explanations
* API documentation continues to be improved, with many new examples
Misc
----
* [rustc no longer hangs when dependencies recursively re-export
submodules]
(https://github.com/rust-lang/rust/pull/34542)
* [rustc requires LLVM 3.7+]
(https://github.com/rust-lang/rust/pull/34104)
* [The 'How Safe and Unsafe Interact' chapter of The Rustonomicon was
rewritten]
(https://github.com/rust-lang/rust/pull/33895)
* [rustc support 16-bit pointer sizes]
(https://github.com/rust-lang/rust/pull/33460).
No targets use this yet, but it works toward AVR support.
Compatibility Notes
-------------------
* [`const`s and `static`s may not have unsized types]
(https://github.com/rust-lang/rust/pull/34443)
* [The new follow-set rules that place restrictions on `macro_rules!`
in order to ensure syntax forward-compatibility have been enabled]
(https://github.com/rust-lang/rust/pull/33982)
This was an [ammendment to RFC 550]
(https://github.com/rust-lang/rfcs/pull/1384),
and has been a warning since 1.10.
* [`cfg` attribute process has been refactored to fix various bugs]
(https://github.com/rust-lang/rust/pull/33706).
This causes breakage in some corner cases.
