* Move private key parsing from serviceaccount/jwt.go to client-go/util/cert ([#40907](https://github.com/kubernetes/kubernetes/pull/40907), [@cblecker](https://github.com/cblecker))
* Caching added to the OIDC client auth plugin to fix races and reduce the time kubectl commands using this plugin take by several seconds. ([#38167](https://github.com/kubernetes/kubernetes/pull/38167), [@ericchiang](https://github.com/ericchiang))

- Avoid caching the Azure VMSS instances whose network profile is nil ([#100948](https://github.com/kubernetes/kubernetes/pull/100948), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]

- Limit use of tags when calling EC2 API to prevent API throttling for very large clusters. ([#76749](https://github.com/kubernetes/kubernetes/pull/76749), [@mcrute](https://github.com/mcrute))

### Bug or Regression

backend storage, etcd, has a new release 3.5.0 and the community embraced it. The new release comes with improvements to the Security, performance, monitoring and developer experience. There are numerous bug fixes to lease objects causing memory leaks, and compact operation causing deadlocks and more. A couple of new features are also introduced like the migration to structured logging and build in log rotation. The release comes with a detailed future roadmap to implement a solution to traffic overload....

    * when updating a service or when node changes occur.
* Allow for watching objects larger than 1MB given etcd accepts objects of size up to 1.5MB ([#72053](https://github.com/kubernetes/kubernetes/pull/72053), [@wojtek-t](https://github.com/wojtek-t))

- For resources built into an apiserver, the server now logs at `-v=3` whether it is using watch caching. ([#109175](https://github.com/kubernetes/kubernetes/pull/109175), [@MikeSpreitzer](https://github.com/MikeSpreitzer)) [SIG API Machinery]

* Deployments are updated to use (1) a more stable hashing algorithm (fnv) than the previous one (adler) and (2) a hashing collision avoidance mechanism that will ensure new rollouts will not block on hashing collisions anymore.
