- Fixed the bug where Events failed to be created when the referenced object name was not a valid Event name. Now, a UUID is used as the name instead of the referenced object name and the timestamp suffix. ([#129790](https://github.com/kubernetes/kubernetes/pull/129790), [@aojea](https://github.com/aojea))

- Fixed a Windows kube-proxy (winkernel) issue where stale `RemoteEndpoints`

  clearing of the `terminatedEndpoints` map. ([#135146](https://github.com/kubernetes/kubernetes/pull/135146), [@princepereira](https://github.com/princepereira)) [SIG Network and Windows]
