- Pkg k8s.io/apiserver/pkg/storage/cacher, method (*Cacher) Wait(context.Context) error ([#125450](https://github.com/kubernetes/kubernetes/pull/125450), [@mauri870](https://github.com/mauri870)) [SIG API Machinery]

### Bug or Regression

  The incorrect loop logic might lead to a plugin being loaded multiple times, consequently preventing any Pod from being scheduled, which is unexpected. ([#122370](https://github.com/kubernetes/kubernetes/pull/122370), [@caohe](https://github.com/caohe)) [SIG Scheduling]

### Other (Cleanup or Flake)

- To reduce chances of throttling, VM cache is set to nil when Azure node provisioning state is deleting ([#87635](https://github.com/kubernetes/kubernetes/pull/87635), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]

- New `KUBECACHEDIR` environment variable was introduced to override default discovery cache directory which is `$HOME/.kube/cache`. ([#109479](https://github.com/kubernetes/kubernetes/pull/109479), [@ardaguclu](https://github.com/ardaguclu))

- Clear pod binding cache on bind error to make sure stale pod binding cache will not be used. ([#71212](https://github.com/kubernetes/kubernetes/pull/71212), [@cofyc](https://github.com/cofyc))
- Fixed a scheduler panic due to internal cache inconsistency ([#71063](https://github.com/kubernetes/kubernetes/pull/71063), [@Huang-Wei](https://github.com/Huang-Wei))

  Similarly you can also access  kubelet's `/pods` endpoint to fetch a list of Pods bound to that node by granting the caller `nodes/pods` permission in RBAC.
  Similarly you can also access kubelet's `/configz` endpoint to fetch kubelet's configuration by granting the caller `nodes/configz` permission in RBAC.

  - The disk-cached discovery client is moved from k8s.io/client-go/discovery to k8s.io/client-go/discovery/cached/disk.
The memory-cached discovery client is moved from k8s.io/client-go/discovery/cached to k8s.io/client-go/discovery/cached/memory.
([#72214](https://github.com/kubernetes/kubernetes/pull/72214), [@caesarxuchao](https://github.com/caesarxuchao))

* The following deprecated flags were removed from `kube-controller-manager`:

  * `replication-controller-lookup-cache-size`
  * `replicaset-lookup-cache-size`
  * `daemonset-lookup-cache-size`

  Don't use these flags. Using deprecated flags causes the server to print a warning. Using a removed flag causes the server to abort the startup.

- Fix the bug PIP's DNS is deleted if no DNS label service annotation isn't set. ([#87312](https://github.com/kubernetes/kubernetes/pull/87312), [@nilo19](https://github.com/nilo19)) [SIG Cloud Provider]
- Fix: set nil cache entry based on old cache ([#87591](https://github.com/kubernetes/kubernetes/pull/87591), [@aramase](https://github.com/aramase)) [SIG Cloud Provider]

* Fixed a bug in the API server watch cache, which could cause a missing watch event immediately after cache initialization. ([#49992](https://github.com/kubernetes/kubernetes/pull/49992), [@liggitt](https://github.com/liggitt))
