 ### API Breaking Changes
 
+* (x/slashing) [17044](https://github.com/cosmos/cosmos-sdk/pull/17044) Use collections for `AddrPubkeyRelation`:
+    * remove from `types`: `AddrPubkeyRelationKey`
+    * remove from `Keeper`: `AddPubkey`
 * (x/staking) [#17260](https://github.com/cosmos/cosmos-sdk/pull/17260) Use collections for `DelegationKey`:
     * remove from `types`: `GetDelegationKey`, `GetDelegationsKey`
 * (x/staking) [#17288](https://github.com/cosmos/cosmos-sdk/pull/17288) Use collections for `UnbondingIndex`:
