## @solana/addresses 8

### New APIs and options

- Adds a type for any object exposing a Solana address through an address property, including TransactionSigner, AccountMeta, and framework address wrappers. The fee payer of a transaction message is now typed using HasAddress. (8.3.0) — [release notes](https://github.com/anza-xyz/kit/releases/tag/v8.3.0)

### Behavior and default changes

- Encodes address-bearing objects implementing HasAddress as well as plain Address values, so signers and wrapper classes can be encoded without unwrapping them. (8.5.0) — [release notes](https://github.com/anza-xyz/kit/releases/tag/v8.5.0)
