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.

• lang: Add seeds::program constraint for specifying which program_id to use when deriving PDAs.(#1197)
• ts: Remove error logging in the event parser when log websocket encounters a program error. (#1313)

Breaking

• lang: rename loader_account module to account_loader module (#1279)

• 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: 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).
