 ### Bug Fixes
 
+* (baseapp) [#21159](https://github.com/cosmos/cosmos-sdk/pull/21159) Return PreBlocker events in FinalizeBlockResponse.
 * (baseapp) [#18727](https://github.com/cosmos/cosmos-sdk/pull/18727) Ensure that `BaseApp.Init` firstly returns any errors from a nil commit multistore instead of panicking on nil dereferencing and before sealing the app.
 * (client) [#18622](https://github.com/cosmos/cosmos-sdk/pull/18622) Fixed a potential under/overflow from `uint64->int64` when computing gas fees as a LegacyDec.
 * (client/keys) [#18562](https://github.com/cosmos/cosmos-sdk/pull/18562) `keys delete` won't terminate when a key is not found.
