 ### Features
 
+* [#18047](https://github.com/cosmos/cosmos-sdk/pull/18047) Added a limit of 200 grants pruned per EndBlock and the method PruneAllowances that prunes 75 expired grants on every run.
 * [#14649](https://github.com/cosmos/cosmos-sdk/pull/14649) The `x/feegrant` module is extracted to have a separate go.mod file which allows it to be a standalone module.
