- Added `optionalOldSelf` to `x-kubernetes-validations` to support ratcheting CRD schema constraints. ([#121034](https://github.com/kubernetes/kubernetes/pull/121034), [@alexzielenski](https://github.com/alexzielenski))

- Fixed nil pointer error in `NodeVolumeLimits` csi logging ([#115179](https://github.com/kubernetes/kubernetes/pull/115179), [@sunnylovestiramisu](https://github.com/sunnylovestiramisu))
- Fixed panic validating custom resource definition schemas that set `multipleOf` to 0 ([#114869](https://github.com/kubernetes/kubernetes/pull/114869), [@liggitt](https://github.com/liggitt))

- 'Container `preStop` and `postStart` lifecycle handlers using `httpGet` now
