- Aggregated roles no longer include write access to `EndpointSlices`. This rolls back part of a change that was introduced earlier in the Kubernetes 1.22 cycle. ([#103703](https://github.com/kubernetes/kubernetes/pull/103703), [@robscott](https://github.com/robscott))

- Fixes a problem with 63-second or 1-second connection delays with some VXLAN-based
  network plugins which was first widely noticed in 1.16 (though some users saw it
  earlier than that, possibly only with specific network plugins). If you were previously
  using ethtool to disable checksum offload on your primary network interface, you should

- Feature gates that graduated to GA in 1.23 or earlier and were unconditionally enabled have been removed: CSIServiceAccountToken, ConfigurableFSGroupPolicy, EndpointSlice, EndpointSliceNodeName, EndpointSliceProxying, GenericEphemeralVolume, IPv6DualStack, IngressClassNamespacedParams, StorageObjectInUseProtection,...

### Bug or Regression

- Removed a warning around Linux user namespaces and kernel version. If the feature gate `UserNamespacesSupport` was enabled, the kubelet previously warned when detecting a Linux kernel version earlier than 6.3.0. User namespace support on Linux typically does still need kernel 6.3 or newer, but it can work in older kernels too.

*   Custom resources served by CustomResourceDefinition objects now support field selectors for `metadata.name` and `metadata.namespace`. Also fixed an issue with watching a single object; earlier versions could watch only a collection, and so a watch on an instance would fail.

- Fix a bug where kube-apiserver could emit an further watch even even if decryption failed for earlier event and it was not emitted. ([#131161](https://github.com/kubernetes/kubernetes/pull/131161), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery]
