 - 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)).
