* kubeadm: the kubeadm init output now provides join control-plane example only when the preconditions for joining a control plane are satisfied ([#75420](https://github.com/kubernetes/kubernetes/pull/75420), [@fabriziopandini](https://github.com/fabriziopandini))

- The client-go dynamic client sets the header 'Content-Type: application/json' by default (#104327, @sxllwx) [SIG API Machinery]
- The pods/binding subresource now honors `metadata.uid` and `metadata.resourceVersion` preconditions (#105913, @aholic) [SIG Scheduling]
- Topology Hints now excludes control plane notes from capacity calculations. (#104744, @robscott) [SIG Apps and Network]

- Fixed a regression in the pod binding subresource to honor the `metadata.uid` precondition.

- Kube-apiserver: fixed a conflict error encountered attempting to delete a pod with gracePeriodSeconds=0 and a resourceVersion precondition ([#85516](https://github.com/kubernetes/kubernetes/pull/85516), [@michaelgugino](https://github.com/michaelgugino)) [SIG API Machinery]

- Fix a bug in the apiserver that could cause a valid update request to be rejected with a precondition check failure. ([#82303](https://github.com/kubernetes/kubernetes/pull/82303), [@roycaihw](https://github.com/roycaihw))

### Other notable changes

* Fix a bug in apiserver that could cause a valid update request to be rejected with a precondition check failure. ([#82303](https://github.com/kubernetes/kubernetes/pull/82303), [@roycaihw](https://github.com/roycaihw))

- Fixed two regressions introduced by the PodDisruptionConditions feature (on by default in 1.26):
  - pod eviction API calls returned spurious precondition errors and required a second evict API call to succeed
