[0.28.0] - 2023-06-09

Features

• client: Add async feature flag to use an asynchronous anchor-client (#2488).
• spl: Add metadata wrappers approve_collection_authority, bubblegum_set_collection_size, burn_edition_nft, burn_nft, revoke_collection_authority, set_token_standard, utilize, unverify_sized_collection_item, unverify_collection (#2430)

• bench: Add benchmarking for compute units usage (#2466)
• cli: idl set-buffer, idl set-authority and idl close take an option --print-only. which prints transaction in a base64 Borsh compatible format but not sent to the cluster. It's helpful when managing authority under a multisig, e.g., a user can create a proposal for a Custom Instruction in SPL Governance (#2486).

• spl: Remove the metadata::create_metadata_account_v2 deprecated wrapper since it was removed from token metadata program (#2480)

[0.27.0] - 2023-03-08

Features

• spl: Add MasterEditionAccount account deserialization to spl metadata (#2393).
• lang: Add the InitSpace derive macro to automatically calculate the space at the initialization of an account (#2346).
• cli: Add env option to verifiable builds (#2325).
• cli: Add idl close command to close a program's IDL account (#2329).
• cli: idl init now supports very large IDL files (#2329).

• cli: Add --arch sbf option to compile programs using cargo build-sbf (#2398).
• land: Support multiple programs with the same interface using Interface and InterfaceAccount types, related to token-2022 (#2386).

Fixes

• ts: Make the return type of AccountClient.fetchMultiple match the account type being fetched (#2390)
• cli: Don't regenerate idl in read_all_programs(). (#2332).
• ts: provider.simulate will send the transaction with sigVerify: false if no signers are present (#2331).
• cli: Failing commands will return the correct exit status. (#2370).
• idl: Update the IDL program to use non-deprecated account types (#2365).
• ts: Enum fields weren't being converted from snake_case to camelCase (#2378).
• lang/cli: Update to solana-program version 1.14.16 and rust version 1.60, appears to still be incompatible with 1.15 CLI (#2420).

Breaking

• lang: Remove deprecated account types: CpiAccount, Loader and ProgramAccount (#2375).
• lang: Remove state and interface attributes (#2285).
• lang: Remove deprecated literal constraint which has been replaced by #[account(constraint = {})] (#2379).
• lang: account(zero_copy) and zero_copy attributes now derive the bytemuck::Pod and bytemuck::Zeroable traits instead of using unsafe impl (#2330). This imposes useful restrictions on the type, like not having padding bytes and all fields being Pod themselves. See bytemuck::Pod for details. This change requires adding bytemuck = { version = "1.4.0", features = ["derive", "min_const_generics"]} to your cargo.toml. Legacy applications can still use #[account(zero_copy(unsafe))] and #[zero_copy(unsafe)] for the old behavior.
• ts: Remove createProgramAddressSync, findProgramAddressSync (now available in @solana/web3.js) and update associatedAddress to be synchronous (#2357).

• lang: Add Discriminator and Owner trait implementation for structures representing instructions (#1997).
• ts: '@coral-xyz/borsh' package is now part of the yarn monorepo (#2290). The borsh package needs to be built before the anchor package can be built but this should happen automatically when running yarn build in packages/anchor, see #2299 and #2306.
• lang: Add support for optionally passing in accounts using the syntax Optional<Account<'info, T>>. Shouldn't affect existing programs but may be a breaking change to tools that use the anchor generated IDL. #2101.

• client: Fix Cluster's FromStr implementation (#1362).
• lang: Implement Key for Pubkey again, so associated_token::* constraints can use pubkey targets again (#1601).
• lang: Adjust error code so #[error_code] works with just importing anchor_lang::error_code (#1610).
• ts: Fix spl-token coder account parsing (#1604).
• cli: Fix npm install fallback if yarn install doesn't work (#1643).
• lang: Fix bug where owner = <target> would not compile because of missing type annotation (#1648).
• ts: Adjust send and simulate functions in provider.ts, so they use the return value of Wallet.signTransaction(#1527).

Breaking

• ts: Mark transaction, instruction, simulate and rpc program namespaces as deprecated in favor of methods (#1539).

[0.22.1] - 2022-02-28

Fixes

• cli: Fix rust template (#1488).
• lang: Handle array sizes with variable sizes in events and array size casting in IDL parsing (#1485)

[0.22.0] - 2022-02-20

Fixes

• ts: Allow nullable types for Option<T> mapped types (#1428).

Breaking

• lang: Enforce that the payer for an init-ed account be marked mut (#1271).
• lang: All error-related code is now in the error module (#1426).
• lang: Require doc comments when using AccountInfo or UncheckedAccount types (#1452).
• lang: add error! and err! macro and Result type (#1462). This change will break most programs. Do the following to upgrade: _ change all ProgramResult's to Result<()> _ change #[error] to #[error_code] _ change all Err(MyError::SomeError.into()) to Err(error!(MyError::SomeError)) and all Err(ProgramError::SomeProgramError) to Err(ProgramError::SomeProgramError.into()) or Err(Error::from(ProgramError::SomeProgramError).with_source(source!())) to provide file and line source of the error (with_source is most useful with ProgramErrors. error! already adds source information for custom and anchor internal errors). _ change all solana_program::program::invoke() to solana_program::program::invoke().map_err(Into::into) and solana_program::program::invoke_signed() to solana_program::program::invoke_signed().map_err(Into::into)

[0.21.0] - 2022-02-07

Fixes

• ts: Fix the root type declaration of the Wallet / NodeWallet class (#1363).
• ts: Improve type mapping of Account fields into Typescript with additional support for Option<T> and Vec<String> types (#1393).

Features

• lang: Add seeds::program constraint for specifying which program_id to use when deriving PDAs (#1197).
• lang: Context now has a new bumps: BTree<String, u8> argument, mapping account name to bump seed "found" by the accounts context. This allows one to access bump seeds without having to pass them in from the client or recalculate them in the handler (#1367).
• lang, ts: Automatically infer PDA addresses (#1331).
• ts: Remove error logging in the event parser when log websocket encounters a program error (#1313).
• ts: Add new methods namespace to the program client, introducing a more ergonomic builder API (#1324).

• cli: Expose the solana-test-validator --account flag in Anchor.toml via test.validator.account (#1366).
• cli: Add avm, a tool for managing anchor-cli versions (#1385).

Breaking

• lang: Put init_if_needed behind a feature flag to decrease wrong usage (#1258).
• lang: rename loader_account module to account_loader module (#1279)
• lang: The Accounts trait's try_accounts method now has an additional bumps: &mut BTreeMap<String, u8> argument, which accumulates bump seeds (#1367).
• lang: Providing bump = <target> targets with init will now error. On init only, it is required to use bump without a target and access the seed inside function handlers via ctx.bumps.get("<pda-account-name"). For subsequent seeds constraints (without init), it is recommended to store the bump on your account and use it as a bump = <target> target to minimize compute units used (#1380).
• ts: Coder is now an interface and the existing class has been renamed to BorshCoder. This change allows the generation of Anchor clients for non anchor programs (#1259).
• cli: test.clone key in Anchor.toml is renamed to test.validator.clone (#1366).

[0.20.1] - 2022-01-09

• ts: Add type declarations for conditional workspace and Wallet exports (#1137).
• ts: Change commitment message recent to processed and max to finalized (#1128)
• ts: fix translateAddress which currently leads to failing browser code. Now uses PublicKey constructor instead of prototype chain constructor name checking which doesn't work in the presence of code minifying/mangling(#1138)
• lang: add missing check that verifies that account is ATA when using init_if_needed and init is not needed(#1221)

Features

• lang: Add programdata_address: Option<Pubkey> field to Program account. Will be populated if account is a program owned by the upgradable bpf loader (#1125)
• lang,ts,ci,cli,docs: update solana toolchain to version 1.8.5(#1133).
