- Fixed a bug where hard evictions due to resource pressure allowed pods
  to use the full termination grace period instead of shutting down instantly. 
  This bug also affected force deleted pods. Both cases now receive a termination grace period of 1 second. ([#124063](https://github.com/kubernetes/kubernetes/pull/124063), [@olyazavr](https://github.com/olyazavr))

  Fixed skip `not found` nodes when reconciling LB backend address pools ([#105188](https://github.com/kubernetes/kubernetes/pull/105188), [@nilo19](https://github.com/nilo19))
- Fixed occasional pod cgroup freeze when using cgroup v1 and systemd driver. ([#104528](https://github.com/kubernetes/kubernetes/pull/104528), [@kolyshkin](https://github.com/kolyshkin))

*   Termination grace period for the calico/node add-on DaemonSet has been eliminated, reducing downtime during a rolling upgrade or deletion. ([#55015](https://github.com/kubernetes/kubernetes/pull/55015),[ @fasaxc](https://github.com/fasaxc))

- The default value for node-monitor-grace-period has been increased to 50s (earlier 40s) (Ref - https://github.com/kubernetes/kubernetes/issues/121793) ([#126287](https://github.com/kubernetes/kubernetes/pull/126287), [@devppratik](https://github.com/devppratik)) [SIG API Machinery, Apps and...

- When deleting objects using kubectl with the --force flag, you are no longer required to also specify --grace-period=0. ([#87776](https://github.com/kubernetes/kubernetes/pull/87776), [@brianpursley](https://github.com/brianpursley)) [SIG CLI]
