- The `EndpointSlice` mirroring controller mirrors endpoints annotations and labels to the generated endpoint slices, it also ensures that updates on any of these fields are mirrored. 
  The well-known annotation `endpoints.kubernetes.io/last-change-trigger-time` is skipped and not mirrored. ([#98116](https://github.com/kubernetes/kubernetes/pull/98116), [@aojea](https://github.com/aojea))

* Fix lint failures on kubernetes-e2e charm ([#45832](https://github.com/kubernetes/kubernetes/pull/45832), [@Cynerva](https://github.com/Cynerva))

### Certificates
* The CertificateSigningRequest API added the `extra` field to persist all information about the requesting user. This mirrors the fields in the SubjectAccessReview API used to check authorization. ([#41755](https://github.com/kubernetes/kubernetes/pull/41755), [@liggitt](https://github.com/liggitt))

- Fix a bug on the `endpointslicemirroring` controller where endpoint `NotReadyAddresses` were mirrored as Ready to the corresponding `EndpointSlice`. ([#102683](https://github.com/kubernetes/kubernetes/pull/102683), [@aojea](https://github.com/aojea))

- The endpointslice mirroring controller mirrors endpoints annotations and labels to the generated endpoint slices, it also ensures that updates on any of these fields on the endpoints are mirrored. 

- Significant kube-proxy performance improvements when using Endpoint Slices at scale. ([#83206](https://github.com/kubernetes/kubernetes/pull/83206), [@robscott](https://github.com/robscott))

### Node
- Mirror pods now include an ownerReference for the node that created them. ([#84485](https://github.com/kubernetes/kubernetes/pull/84485), [@tallclair](https://github.com/tallclair))

 - Static pods that reference API objects were denied admission by the kubelet so that static pods would not be silently running even after the mirror pod creation failed.
