- Feature gate dependencies are now explicit, and validated at startup. A feature can no longer be enabled if it depends on a disabled feature. In particular, this means that `AllAlpha=true` will no longer work without enabling disabled-by-default beta features that are depended on (either with `AllBeta=true` or explicitly enumerating the disabled dependencies). ([#133697](https://github.com/kubernetes/kubernetes/pull/133697), [@tallclair](https://github.com/tallclair)) [SIG API Machinery,...

- The `DeclarativeValidation` feature gate is enabled by default. When enabled, mismatches with existing hand written validation is reported via metrics.

* kube-apiserver: `--runtime-config` can once again be used to enable/disable serving specific resources in the `extensions/v1beta1` API group. Note that specific resource enablement/disablement is only allowed for the `extensions/v1beta1` API group for legacy reasons. Attempts to enable/disable individual resources in other API groups will print a warning, and will return an error in future releases. ([#72249](https://github.com...

- Introduce a feature gate `DisableCloudProviders` allowing to disable cloud-provider initialization in KAPI, KCM and kubelet.

DOS vulnerabilities for `CVE-2023-44487` and `CVE-2023-39325` for the API server when the client is unauthenticated. The mitigation may be disabled by setting the `UnauthenticatedHTTP2DOSMitigation` feature gate to `false` (it is enabled by default). An API server fronted by an L7 load balancer that already mitigates these http/2 attacks may choose to disable the kube-apiserver mitigation to avoid disrupting load balancer -> kube-apiserver connections if http/2 requests from multiple clients share...

- Disable watchcache for events ([#96052](https://github.com/kubernetes/kubernetes/pull/96052), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery]

- GCE/Windows: disabled stackdriver logging agent to prevent node startup failures ([#76099](https://github.com/kubernetes/kubernetes/pull/76099), [@yujuhong](https://github.com/yujuhong))

  
  The feature gate `DisableKubeletCloudCredentialProviders` is currently in Alpha, which means is currently disabled by default. Once this feature gate moves to beta, in-tree credential providers will be disabled by default, and users will need to migrate to use external credential providers.

  * Fix incorrect CPU usage with 4.7 kernel
  * OOM parser uses kmsg
  * Add hugepages support
  * Add CRI-O support

* Sharing a PID namespace between containers in a pod is disabled by default in version 1.8. To enable for a node, use the `--docker-disable-shared-pid=false` kubelet flag. Be aware that PID namespace sharing requires Docker version greater than or equal to 1.13.1.

* Fix issues related to the eviction manager.

resource version.  Previously when listing resources that had the watch cache disabled clients could retrieve a snapshot at that exact resource version.  If the client requests a resource version newer than the current state, a TimeoutError is returned suggesting the client retry in a few seconds.  This behavior is now consistent for both single item retrieval and list calls, and for when the watch cache is enabled or disabled.
