 ### API Breaking Changes
 
+* (x/staking) [#17256](https://github.com/cosmos/cosmos-sdk/pull/17256) Use collections for `UnbondingID`.
 * (x/staking) [#17260](https://github.com/cosmos/cosmos-sdk/pull/17260) Use collections for `ValidatorByConsAddr`:
     * remove from `types`: `GetValidatorByConsAddrKey`
 * (x/staking) [#17248](https://github.com/cosmos/cosmos-sdk/pull/17248) Use collections for `UnbondingType`.
