1.1.1

See the full CHANGELOG.

How to upgrade

Common steps

1. Update Anchor crate(s) to 1.1.1.

2. Update TS package(s) to 1.1.1.

Recommended Solana Version

The recommended Solana version is 3.1.10, unchanged from 1.0.0.

Lang

Fix #[event_cpi] deprecation warnings

#[event_cpi] was making use of deprecated AccountInfo accounts internally. This has been updated to use the recommended UncheckedAccount instead, silencing the noisy warnings.

Re-add the legacy IDL handlers

In 1.0.0, we changed the mechanism for storing the IDL on chain from automatically generated instruction handlers to the Solana Program Metadata Program. This resulted in large binary size and security wins, but caused breakage for developers relying on this mechanism. This functionality has been re-added. You can opt in with:

#[program(legacy_idl)]
pub mod my_program {
    // ...
}

And interact with it using anchor legacy-idl.

CLI

Remove hard build error with mismatched keys

Previously, anchor build verified that the program's private keypair matched the declare_id pubkey. This was a pain point for developers collaborating on Anchor projects, as private keys would typically not be checked into version control.

This has been made into a soft error; the warning is still printed, but does not block builds. --ignore-keys can still be used to silence this.

More reliable handling of relative paths

The CLI now performs more reliable normalization of input paths. This means that relative paths (including when invoking anchor in a subdirectory) will be handled more predictably.

Optimized build times

Previously, the CLI built programs in a naive order, which resulted in bottlenecking on certain dependencies. The CLI will now attempt to be smarter when building packages, which can provide compile-time speedups of up to 50%.
