- Traffic to a service IP now starts getting rejected (as opposed to
      merely dropped) as soon as there are no longer any *usable*
      endpoints, rather than waiting until all of the terminating
      endpoints have terminated even when those terminating endpoints
      were not being used.
  
    - Chains for endpoints that won't be used are no longer output to

- 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))

- Fixes a regression in kube-apiserver causing 500 errors from the `/readyz` endpoint ([#93643](https://github.com/kubernetes/kubernetes/pull/93643), [@ialidzhikov](https://github.com/ialidzhikov)) [SIG API Machinery]
- Terminating a restartPolicy=Never pod no longer has a chance to report the pod succeeded when it actually failed. ([#88440](https://github.com/kubernetes/kubernetes/pull/88440), [@smarterclayton](https://github.com/smarterclayton)) [SIG Node and Testing]

- Kubelet: Fix the volume manager didn't check the device mount state in the actual state of the world before marking the volume as detached. It may cause a pod to be stuck in the Terminating state due to the above issue when it was deleted.

## Dependencies

### Added
_Nothing has changed._

* Fix race condition introduced by graceful termination which can lead to a deadlock in kube-proxy ([#72361](https://github.com/kubernetes/kubernetes/pull/72361), [@lbernail](https://github.com/lbernail))
* Support graceful termination with IPVS when deleting a service ([#71895](https://github.com/kubernetes/kubernetes/pull/71895), [@lbernail](https://github.com/lbernail))

  a user to request FallbackToLogsOnError, which will read from the container's
  logs to populate the termination message if the user does not write to the
  termination message log file. The termination message file is now properly
  readable for end users and has a maximum size (4k bytes) to prevent abuse.
  Each pod may have up to 12k bytes of termination messages before the contents
  of each will be truncated.

* Return apiserver panics as 500 errors instead terminating the apiserver process. ([#68001](https://github.com/kubernetes/kubernetes/pull/68001), [@sttts](https://github.com/sttts))

* kube-proxy in IPVS mode will stop initiating connections to terminating pods for services with sessionAffinity set. ([#71834](https://github.com/kubernetes/kubernetes/pull/71834), [@lbernail](https://github.com/lbernail))

- Fixed a bug that caused a DaemonSet rolling update to hang when its pod gets stuck at terminating.  ([#77773](https://github.com/kubernetes/kubernetes/pull/77773), [@DaiHao](https://github.com/DaiHao))

- Implemented a new status field, `.status.terminatingReplicas`, for Deployments and ReplicaSets to track terminating pods. The new field is present when the `DeploymentPodReplacementPolicy` feature gate is enabled. ([#128546](https://github.com/kubernetes/kubernetes/pull/128546), [@atiratree](https://github.com/atiratree)) [SIG API Machinery, Apps and Testing]...
