 * (x/genutil) [#15999](https://github.com/cosmos/cosmos-sdk/pull/15999) Genutil now takes the `GenesisTxHanlder` interface instead of deliverTx. The interface is implemented on baseapp
 * (types/math) [#16040](https://github.com/cosmos/cosmos-sdk/pull/16040) Remove unused aliases in math.go
 * (x/gov) [#16106](https://github.com/cosmos/cosmos-sdk/pull/16106) Remove gRPC query methods from Keeper
+* (x/gov) [#16118](https://github.com/cosmos/cosmos-sdk/pull/16118/) Use collections for constituion and params state management.

 ### Client Breaking Changes
 
 * (x/staking) [#15701](https://github.com/cosmos/cosmos-sdk/pull/15701) `HistoricalInfoKey` now has a binary format.
