CHANGELOG.md

Changelog

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

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Note: Version 0 of Semantic Versioning is handled differently from version 1 and above. The minor version will be incremented upon a breaking change and the patch version will be incremented for features.

[Unreleased]

Features

• cli: Add support for configuration options for solana-test-validator in Anchor.toml (#834).
• cli: target/types directory now created on build to store a TypeScript types file for each program's IDL (#795).
• ts: Program<T> can now be typed with an IDL type (#795).
• lang: Add mint::freeze_authority keyword for mint initialization within #[derive(Accounts)] (#835).
• lang: Add AccountLoader type for zero_copy accounts with support for CPI (#792).

Breaking

• lang: Accounts marked with the #[account(signer)] constraint now enforce signer when the "cpi" feature is enabled (#849).

[0.17.0] - 2021-10-03

Features

• cli: Add localnet command for starting a local solana-test-validator with the workspace deployed (#820).

Breaking

• CpiContext accounts must now be used with the accounts struct generated in the crate::cpi::accounts::* module. These structs correspond to the accounts context for each instruction, except that each field is of type AccountInfo (#824).

[0.16.2] - 2021-09-27

Features

• lang: Add --detach flag to anchor test (#770).
• lang: Add associated_token keyword for initializing associated token accounts within #[derive(Accounts)] (#790).
• cli: Allow passing through cargo flags for build command (#719).
• cli: Allow passing through cargo flags for test, verify, and publish commands (#804).

Fixes

• lang: Generated AccountMetas for Rust clients now properly set the isSigner field (#762).

[0.16.1] - 2021-09-17

Fixes

• lang: Signer type now sets isSigner to true in the IDL (#750).

[0.16.0] - 2021-09-16

Features

• lang: Program type introduced for executable accounts (#705).
• lang: Signer type introduced for signing accounts where data is not used (#705).
• lang: UncheckedAccount type introduced as a preferred alias for AccountInfo (#745).

Breaking Changes

• lang: #[account(owner = <pubkey>)] now requires a Pubkey instead of an account (#691).

[0.15.0] - 2021-09-07

Features

• lang: Add new Account type to replace ProgramAccount and CpiAccount, both of which are deprecated (#686).
• lang: Box can be used with Account types to reduce stack usage (#686).
• lang: Add Owner trait, which is automatically implemented by all #[account] structs (#686).
• lang: Check that ProgramAccount writable before mut borrow (anchor-debug only) (#681).

Breaking Changes

• lang: All programs must now define their program id in source via declare_id! (#686).

[0.14.0] - 2021-09-02

Features

• lang: Ignore Unnamed structs instead of panic (#605).
• lang: Add constraints for initializing mint accounts as pdas, #[account(init, seeds = [...], mint::decimals = <expr>, mint::authority = <expr>)] (#562).
• lang: Add AsRef<AccountInfo> for AccountInfo wrappers (#652).
• lang: Optimize trait Key by removing AccountInfo cloning (#652).
• cli, client, lang: Update solana toolchain to v1.7.11 (#653).

• lang: #[associated] and #[account(associated = <target>, with = <target>)] are both removed (#612).
• cli: Removed anchor launch command (#634).
• lang: #[account(init)] now creates the account inside the same instruction to be consistent with initializing PDAs. To maintain the old behavior of init, replace it with #[account(zero)] (#641).
• lang: bump must be provided when using the seeds constraint. This has been added as an extra safety constraint to ensure that whenever a PDA is initialized via a constraint the bump used is the one created by Pubkey::find_program_address (#641).
• lang: try_from_init has been removed from Loader, ProgramAccount, and CpiAccount and replaced with try_from_unchecked (#641).
• lang: Remove AccountsInit trait (#641).
