 ### Improvements
 
+* (x/gov) [#17354](https://github.com/cosmos/cosmos-sdk/issues/17354) Emit `VoterAddr` in `proposal_vote` event.
 * (x/group, x/gov) [#17220](https://github.com/cosmos/cosmos-sdk/pull/17220) Add `--skip-metadata` flag in `draft-proposal` to skip metadata prompt.
 * (x/genutil) [#17296](https://github.com/cosmos/cosmos-sdk/pull/17296) Add `MigrateHandler` to allow reuse migrate genesis related function.
     * In v0.46, v0.47 this function is additive to the `genesis migrate` command. However in v0.50+, adding custom migrations to the `genesis migrate` command is directly possible.
