- Fixed an issue in kube-apiserver, allowing it to recover from an established connection to an incorrect server that never returns the expected response during APIService availability checks.

* Added Establishing Controller on CRDs to avoid race between Established condition and CRs actually served. In HA setups, the Established condition is delayed by 5 seconds. ([#63068](https://github.com/kubernetes/kubernetes/pull/63068), [@xmudrii](https://github.com/xmudrii))

*   You can once again use 0 values for conntrack min, max, max per core, tcp close wait timeout, and tcp established timeout; this functionality was broken in 1.8. ([#55261](https://github.com/kubernetes/kubernetes/pull/55261),[ @ncdc](https://github.com/ncdc))

#### **CoreDNS**

`cpu-manager-policy=static` is configured, containers meeting the qualifications for static cpu assignment (i.e. Containers with integer CPU `requests` in pods with `Guaranteed` QOS) will not have cfs quota enforced. Because this fix changes a long-established behavior, users observing a regressions can use the `DisableCPUQuotaWithExclusiveCPUs` feature gate (enabled by default) to restore the previous behavior. Please file an issue if you encounter problems and have to use the Feature Gate. ([#12752...

- Kube-apiserver: fixed a 1.27+ regression watching a single namespace via the deprecated /api/v1/watch/namespaces/$name endpoint where watch events were not delivered after the watch was established.
