 ### State Machine Breaking
 
+* (codec) [#13196](https://github.com/cosmos/cosmos-sdk/pull/13196) Register all modules' `Msg`s with gov's ModuleCdc so that Amino sign bytes are correctly generated.
 * (x/distribution) [#12852](https://github.com/cosmos/cosmos-sdk/pull/12852) Deprecate `CommunityPoolSpendProposal`. Please execute a `MsgCommunityPoolSpend` message via the new v1 `x/gov` module instead. This message can be used to directly fund the `x/gov` module account.
 * (x/bank) [#12610](https://github.com/cosmos/cosmos-sdk/pull/12610) `MsgMultiSend` now allows only a single input.
 * (x/bank) [#12630](https://github.com/cosmos/cosmos-sdk/pull/12630) Migrate `x/bank` to self-managed parameters and deprecate its usage of `x/params`.
