 ### Features
 
+* (x/staking) [#18142](https://github.com/cosmos/cosmos-sdk/pull/18142) introduce `key_rotation_fee` param to calculate fees while rotating the keys
 * (server) [#18110](https://github.com/cosmos/cosmos-sdk/pull/18110) Start gRPC & API server in standalone mode
 * (client) [#18101](https://github.com/cosmos/cosmos-sdk/pull/18101) Add a `keyring-default-keyname` in `client.toml` for specifying a default key name, and skip the need to use the `--from` flag when signing transactions.
 * (tests) [#17868](https://github.com/cosmos/cosmos-sdk/pull/17868) Added helper method `SubmitTestTx` in testutil to broadcast test txns to test e2e tests.
