  - [stable] When replica sets cannot create pods, they will now report detail via the API about the underlying reason ([kubernetes/features#120](https://github.com/kubernetes/enhancements/issues/120))

- Fix memory leak in kube-apiserver when underlying time goes forth and back. ([#96266](https://github.com/kubernetes/kubernetes/pull/96266), [@chenyw1990](https://github.com/chenyw1990)) [SIG API Machinery]

Dormouse turned out, and, by the time they had settled down
again, the cook had disappeared.

  `Never mind!' said the King, with an air of great relief.
`Call the next witness.'  And he added in an undertone to the
Queen, `Really, my dear, YOU must cross-examine the next witness.
It quite makes my forehead ache!'

* [alpha] Volume resizing

  * You can now increase the size of a volume by calling the Kubernetes API.

  * For alpha, this feature increases only the size of the underlying volume. It does not support resizing the file system.

  * For alpha, volume resizing supports only Gluster volumes.

resourceVersion from the watch cache by default, as in <1.27 (disabling the change in #115096 by default). This mitigates the impact of an etcd watch bug (https://github.com/etcd-io/etcd/pull/17555). If the 1.27 change in #115096 to serve these requests from underlying storage is still desired despite the impact on watch stability, it can be re-enabled with a `WatchFromStorageWithoutResourceVersion` feature gate.
