Changelog

All notable changes to this project will be documented in this file.

[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).

  • 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).

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).

• 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).

Features

• lang: Add ErrorCode::AccountNotInitialized error to separate the situation when the account has the wrong owner from when it does not exist (#1024).
• lang: Called instructions now log their name by default. This can be turned off with the no-log-ix-name flag (#1057).
• lang: ProgramData and UpgradableLoaderState can now be passed into Account as generics. see UpgradeableLoaderState. UpgradableLoaderState can also be matched on to get ProgramData, but when ProgramData is used instead, anchor does the serialization and checking that it is actually program data for you (#1095).
• ts: Add better error msgs in the ts client if something wrong (i.e. not a pubkey or a string) is passed in as an account in an instruction accounts object (#1098).
