 * <h3>Additional notes</h3>

- This PR adds additional validation for endpoint ip configuration while iterating through queried endpoint list. ([#117224](https://github.com/kubernetes/kubernetes/pull/117224), [@princepereira](https://github.com/princepereira)) [SIG Network and Windows]

## Changelog since v1.5.2

### Other notable changes

* We change the default attach_detach_controller sync period to 1 minute to reduce the query frequency through cloud provider to check whether volumes are attached or not.  ([#41363](https://github.com/kubernetes/kubernetes/pull/41363), [@jingxu97](https://github.com/jingxu97))
