 * (x/genutil)[#12956](https://github.com/cosmos/cosmos-sdk/pull/12956) `genutil.AppModuleBasic` has a new attribute: genesis transaction validation function. The existing validation logic is implemented in `genutiltypes.DefaultMessageValidator`. Use `genutil.NewAppModuleBasic` to create a new genutil Module Basic.
 * (codec) [#12964](https://github.com/cosmos/cosmos-sdk/pull/12964) `ProtoCodec.MarshalInterface` now returns an error when serializing unregistered types and a subsequent `ProtoCodec.UnmarshalInterface` would fail.
 * (x/staking) [#12973](https://github.com/cosmos/cosmos-sdk/pull/12973) Removed `stakingkeeper.RandomValidator`. Use `testutil.RandSliceElem(r, sk.GetAllValidators(ctx))` instead.
+* (x/gov) [13160](https://github.com/cosmos/cosmos-sdk/pull/13160) Remove custom marshaling of proposl and voteoption.
