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.

• 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).

• 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• lang: Remove deprecated literal constraint which has been replaced by #[account(constraint = {})] (#2379).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.

• lang: Add support for logging expected and actual values and pubkeys. Add require_eq and require_keys_eq macros. Add default error code to require macro (#1572).
• lang: Add system_program CPI wrapper functions. Make system_program module public instead of re-exporting system_program::System(#1629).
• cli: avm use no long prompts [y/n] if an install is needed first - it just tells the user to avm install (#1565)
• ts: Add AnchorError with program stack and also a program stack for non-AnchorError errors (#1640). AnchorError is not returned for processed tx that have skipPreflight set to true (it falls back to ProgramError or the raw solana library error).

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

• 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).

• 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).

• 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: Improved error msgs when required programs are missing when using the init constraint(#1257)

• 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)

• 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).
• lang: Account wrappers for non-Anchor programs no longer have to implement the serialize function because it has a default impl now. Similarly, they no longer have to implement try_deserialize which now delegates to try_deserialize_unchecked by default(#1156).
• lang: Add set_inner method to Account<'a, T> to enable easy updates (#1177).
• lang: Handle arrays with const as length (#968).
• ts: Add optional commitment argument to fetch and fetchMultiple (#1171).
• lang: Implement AsRef<T> for Account<'a, T>(#1173)

• 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).
