- Apply fsGroup policy for ReadWriteOncePod volumes ([#128244](https://github.com/kubernetes/kubernetes/pull/128244), [@gnufied](https://github.com/gnufied)) [SIG Storage and Testing]

- Fixed file permission issues that happened during update of `Secret`/`ConfigMap`/`projected volume` when `fsGroup` is used. The problem caused a race condition where application gets intermittent permission denied error when reading files that were just updated, before the correct permissions were applied. ([#114464](https://github.com/kubernetes/kubernetes/pull/114464),...
