- The PR adds functionality to generate events when a PV or PVC processing encounters certain failures. The events help users to know the reason for the failure so they can take necessary recovery actions.

* Fix problem with /bin/bash ending up linked to dash  ([#55018](https://github.com/kubernetes/kubernetes/pull/55018), [@dims](https://github.com/dims))

### Bug or Regression

- Check for newer resize fields when deciding recovery feature's status in kubelet ([#131437](https://github.com/kubernetes/kubernetes/pull/131437), [@gnufied](https://github.com/gnufied)) [SIG Storage]

optional flag "--maximum-startup-sequence-duration". This allows you to explicitly define an upper bound on the apiserver startup sequences before healthz begins to fail. By keeping the kubelet liveness initial delay short, this can enable quick kubelet recovery as soon as we have a boot sequence which has not completed in our expected time frame, despite lack of completion from longer boot sequences (like RBAC). Kube-apiserver behavior when the value of this flag is zero is backwards compatible (this is...
