 ### Features
 
+* [#21531](https://github.com/cosmos/cosmos-sdk/pull/21531) Add `registry.AminoRegistrar` to register types on the amino codec from modules.
+* [#21222](https://github.com/cosmos/cosmos-sdk/pull/21222) Make `Iterator` a type alias so that `KVStore` is structurally typed.
 * [#21166](https://github.com/cosmos/cosmos-sdk/pull/21166) Comment out `appmodule.HasServices` to simplify dependencies. This interface is however still supported.

 * [#18379](https://github.com/cosmos/cosmos-sdk/pull/18379) Add branch service.
