 ### API Breaking Changes
 
+* (x/simulation)[#20056](https://github.com/cosmos/cosmos-sdk/pull/20056) `SimulateFromSeed` now takes an address codec as argument.
 * (x/crisis) [#20043](https://github.com/cosmos/cosmos-sdk/pull/20043) Changed `NewMsgVerifyInvariant` to accept a string as argument instead of an `AccAddress`.
 * (x/genutil) [#19926](https://github.com/cosmos/cosmos-sdk/pull/19926) Removal of the Address.String() method and related changes:
     * Added an address codec as an argument to `CollectTxs`, `GenAppStateFromConfig`, and `AddGenesisAccount`.
