 * (cli) [#20779](https://github.com/cosmos/cosmos-sdk/pull/20779) Added `module-hash-by-height` command to query and retrieve module hashes at a specified blockchain height, enhancing debugging capabilities.
 
+### Improvements
+
+* (x/bank) [#21460](https://github.com/cosmos/cosmos-sdk/pull/21460) Added `Sender` attribute in `MsgMultiSend` event.

 ### Bug Fixes
 
 * (baseapp) [#21256](https://github.com/cosmos/cosmos-sdk/pull/21256) Halt height will not commit the block indicated, meaning that if halt-height is set to 10, only blocks until 9 (included) will be committed. This is to go back to the original behavior before a change was introduced in v0.50.0.
