• spl: Update spl/governance to use new errors (#1582).
• client: Fix Cluster's FromStr implementation (#1362).
• lang: Implement Key for Pubkey again, so associated_token::* constraints can use pubkey targets again (#1601).

• ts: Fix spl-token coder account parsing (#1604).

[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

Features

• lang: Add check that declared id == program id (#1451).
• ts: Added float types support (#1425).
• cli: Add --skip-lint option to disable check linting introduced in (#1452) for rapid prototyping (#1482).

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).
• ts: Add registry utility for fetching the latest verified build (#1371).
• 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).
