* Fix SessionAffinity not updated issue for Azure load balancer ([#64180](https://github.com/kubernetes/kubernetes/pull/64180), [@feiskyer](https://github.com/feiskyer))
* Fixes a hang on kubelet startup when using systemd cgroup driver of libcontainer. ([#61926](https://github.com/kubernetes/kubernetes/pull/61926), [@filbranden](https://github.com/filbranden))

* kubelet: resolved hang/timeout issues when running large numbers of pods with unique configmap/secret references ([#74755](https://github.com/kubernetes/kubernetes/pull/74755), [@liggitt](https://github.com/liggitt))

- Fixed a regression error when proxying responses from aggregated API servers, which could cause watch requests to hang until the first event was received. ([#75887](https://github.com/kubernetes/kubernetes/pull/75887), [@liggitt](https://github.com/liggitt))

- KCM sets the upper-bound timeout limit for outgoing requests to 70s. Previously no timeout was set. Requests without explicit timeout might potentially hang forever and lead to starvation of the application.
