SystemAccount<'info> account type for generic wallet addresses or accounts owned by the system program (#954)idl parse subcommand (#941).os and cpu to npm package @project-serum/anchor-cli (#976).solana-test-validator in Anchor.toml (#834).target/types directory now created on build to store a TypeScript types file for each program's IDL (#795).Program<T> can now be typed with an IDL type (#795).mint::freeze_authority keyword for mint initialization within #[derive(Accounts)] (#835).AccountLoader type for zero_copy accounts with support for CPI (#792).#[account(init_if_needed)] keyword for allowing one to invoke the same instruction even if the account was created already (#906).signer, mut, has_one, owner, raw constraints and address (#905, #913).#[account(signer)] constraint now enforce signer when the "cpi" feature is enabled (#849).localnet command for starting a local solana-test-validator with the workspace deployed (#820).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).--detach flag to anchor test (#770).associated_token keyword for initializing associated token accounts within #[derive(Accounts)] (#790).AccountMetas for Rust clients now properly set the isSigner field (#762).Signer type now sets isSigner to true in the IDL (#750).Program type introduced for executable accounts (#705).Signer type introduced for signing accounts where data is not used (#705).UncheckedAccount type introduced as a preferred alias for AccountInfo (#745).#[account(owner = <pubkey>)] now requires a Pubkey instead of an account (#691).Account type to replace ProgramAccount and CpiAccount, both of which are deprecated (#686).Box can be used with Account types to reduce stack usage (#686).Owner trait, which is automatically implemented by all #[account] structs (#686).anchor-debug only) (#681).declare_id! (#686).Unnamed structs instead of panic (#605).#[account(init, seeds = [...], mint::decimals = <expr>, mint::authority = <expr>)] (#562).AsRef<AccountInfo> for AccountInfo wrappers (#652).trait Key by removing AccountInfo cloning (#652).#[account(init, seeds = [...], token = <expr>, authority = <expr>)] to #[account(init, token::mint = <expr> token::authority = <expr>)] (#562).#[associated] and #[account(associated = <target>, with = <target>)] are both removed (#612).anchor launch command (#634).#[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).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).try_from_init has been removed from Loader, ProgramAccount, and CpiAccount and replaced with try_from_unchecked (#641).AccountsInit trait (#641).try_from methods for ProgramAccount, Loader, and ProgramState now take in an additional program_id: &Pubkey parameter (#660).anchor init command "Workspace not found" regression (#598).[registry] section in the Anchor toml (#570).anchor login <api-token> command (#570).anchor publish <package> command (#570).anchor_version field to the Anchor.toml for specifying the anchor docker image to use for verifiable builds (#570).solana_version field to the Anchor.toml for specifying the solana toolchain to use for verifiable builds (#570).init (#587).[clusters.<network>] Anchor.toml section has been renamed to [programs.<network>] (#570).[workspace] member and exclude arrays must now be filepaths relative to the workpsace root (#570).members / exclude in config programs section (#546).clusters.localnet (#554).hex by default for decoding Instruction (#547).CpiAccount::reload mutates the existing struct instead of returning a new one (#526).[scripts] test command (#550).require macro for specifying assertions that return error codes on failure (#483).bump keyword is added to the accounts constraints, which is used to add an optional bump seed to the end of a seeds array. When used in conjunction with both init and seeds, then the program executes find_program_address to assert that the given bump is the canonical bump (#483)..spec suffix on TypeScript tests files (#441).belongs_to constraint (#459).#[account(address = <expr>)] constraint for asserting the address of an account (#400).#[account(init, token = <mint-target>, authority = <token-owner-target>...)] constraint for initializing SPL token accounts as program derived addresses for the program. Can be used when initialized via seeds or associated (#400).associated_seeds! macro for generating signer seeds for CPIs signed by an #[account(associated = <target>)] account (#400).[scripts] section to the Anchor.toml for specifying workspace scripts that can be run via anchor run <script> (#400).[clusters.<network>] table entries can now also use { address = <base58-str>, idl = <filepath-str> } to specify workspace programs (#400).--yarn flag in favor of using npx (#432).&[u8] parameter (#386).--program-name option for build command to build a single program at a time (#362).#[account(close = <destination>)] constraint for closing accounts and sending the rent exemption lamports to a specified destination account (#371).remaining_accounts with CpiContext by implementing the ToAccountMetas trait on CpiContext (#351).SetAuthority instruction (#307).constraint = <expression> added as a replacement for (the now deprecated) string literal constraints (#341).anchor.workspace clients (#310).<program>.account.<my-account> and <program>.state namespaces now require explicitly invoking the fetch API. For example, program.account.myAccount(<adddress>) and program.state() is now program.account.myAccount.fetch(<address>) and program.state.fetch() (#322).#[account(associated)] now requires init to be provided to create an associated account. If not provided, then the address will be assumed to exist, and a constraint will be added to ensure the correctness of the address (#318).#[state] account discriminator to be namespaced by "state:" (#320).: to be consistent with accounts (#321).mut (#341).space constraints must now be literal integers instead of literal strings (#341).program.simulate namespace (#266).Address type, allowing one to use Base 58 encoded strings in public APIs (#304).web3.Account with web3.Signer in public APIs (#296).anchor.workspace clients can now be customized per network with [cluster.<slug>] in the Anchor.toml (#308).--skip-build flag to test command (301).anchor shell command to spawn a node shell populated with an Anchor.toml based environment (#303).wallet and cluster settings must now be under the [provider] table (#305).decode API changed to decode strings directly instead of buffers (#292).encode API removed (#292).anchor-debug feature flag for logging (#253).RequestBuilder::new to RequestBuilder::from (#248).instruction::state::Ctor struct to instruction::state::New (#248).with targets when creating associated acconts (#197).#[account(owner = <program>)] constraint (#178).#[account(associated = <target>)] and #[associated] attributes for creating associated program accounts within programs. The TypeScript package can fetch these accounts with a new <program>.account.<account-name>.associated (and associatedAddress) method (#186).#[account]s are now parsed into the IDL correctly (#177).#[state] account's size (#121).#[account(executable)] attribute (#140).Cluster struct when constructing clients (#89).IdlAccount to be namespaced by "internal" (#128).-#![feature(proc_macro_hygiene)]. (#139).IdlInstruction::Clear (#107)..anchor/program-logs directory when testing (ce5ca7).Initial release.
