 ### Features
 
+- lang: Change all accounts to have a reference to `AccountInfo` ([#2656](https://github.com/coral-xyz/anchor/pull/2656)).
 - lang: Add `get_lamports`, `add_lamports` and `sub_lamports` methods for all account types ([#2552](https://github.com/coral-xyz/anchor/pull/2552)).
 - client: Add a helper struct `DynSigner` to simplify use of `Client<C> where <C: Clone + Deref<Target = impl Signer>>` with Solana clap CLI utils that loads `Signer` as `Box<dyn Signer>` ([#2550](https://github.com/coral-xyz/anchor/pull/2550)).
 - lang: Allow CPI calls matching an interface without pinning program ID ([#2559](https://github.com/coral-xyz/anchor/pull/2559)).
