[0.20.1] - 2022-01-09

Fixes

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

Features

• lang: Allow repr overrides for zero copy accounts (#1273).

Breaking

• 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).

[0.20.0] - 2022-01-06

Fixes

• lang: init_if_needed now checks rent exemption when init is not needed (#1250).
• lang: Add missing owner check when associated_token::authority is used (#1240).
• 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)

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).
• 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)
• cli: Add anchor expand command which wraps around cargo expand (#1160)

Breaking

• client: Client::new and Client::new_with_options now accept Rc<dyn Signer> instead of Keypair (#975).
• lang, ts: Change error enum name and message for 'wrong program ownership' account validation (#1154).
• lang: Change from #[repr(packed)] to #[repr(C)] for zero copy accounts (#1106).
• lang: Account types can now be found either in the prelude module or the accounts module but not longer directly under the root. Deprecated account types are no longer imported by the prelude (#1208).
