- The `EndpointSlice` API is now GA. The `EndpointSlice` topology field has been removed from the GA API and will be replaced by a new per Endpoint Zone field. If the topology field was previously used, it will be converted into an annotation in the v1 Resource. The `discovery.k8s.io/v1alpha1` API is removed.

- Added a "reason" field to the "image_garbage_collected_total" metric, allowing administrators to differentiate between images that were collected for reasons "age" vs "space".

- Protobuf serialization of metav1.MicroTime timestamps (used in `Lease` and `Event` API objects) has been corrected to truncate to microsecond precision, to match the documented behavior and JSON/YAML serialization. Any existing persisted data is truncated to microsecond when read from etcd. ([#111936](https://github.com/kubernetes/kubernetes/pull/111936), [@...

does not support protobuf encoding, if you roll back to 1.5 after upgrading to
protobuf you will be forced to restore from backup, and you will lose any changes
since you converted to protobuf.  After conversion to protobuf, you should
validate the correct operation of your cluster thoroughly before returning it
to normal operation.

- Because of the implementation logic of `time.Format` in golang, the displayed time zone is not consistent. ([#102366](https://github.com/kubernetes/kubernetes/pull/102366), [@cndoit18](https://github.com/cndoit18))
- Corrected the documentation for escaping dollar signs in a container's env, command and args property. ([#101916](https://github.com/kubernetes/kubernetes/pull/101916), [@MartinKanters](https://github.com/MartinKanters)) [SIG Apps]
