- When attaching iSCSI volumes, kubelet now scans only the specific LUNs being attached, and also deletes them after detaching. This avoids dangling references to LUNs that no longer exist, which used to be the cause of random I/O errors/timeouts in kernel logs, slowdowns during block-device related operations, and very rare cases of data corruption....

* Add cache for VM get operation in azure cloud provider ([#57432](https://github.com/kubernetes/kubernetes/pull/57432), [@karataliu](https://github.com/karataliu))

* Configurable liveness probe initial delays for etcd and kube-apiserver in GCE ([#57749](https://github.com/kubernetes/kubernetes/pull/57749), [@wojtek-t](https://github.com/wojtek-t))

- Kube-apiserver now deletes expired kube-apiserver Lease objects:
  - The feature is under feature gate `APIServerIdentity`.

- Increased the maximum backoff delay of the endpointslice controller to match the expected sequence of delays when syncing Services. ([#112353](https://github.com/kubernetes/kubernetes/pull/112353), [@dgrisonnet](https://github.com/dgrisonnet))

### Bug or Regression

- Fix bug that prevents the alpha feature PodTopologyLabelAdmission to not work due to checking for the incorrect label key when copying topology labels. This bug delays the graduation of the feature to beta by an additional release to allow time for meaningful feedback. ([#132462](https://github.com/kubernetes/kubernetes/pull/132462), [@munnerz](https://github.com/munnerz)) [SIG Node]

- Failed pods associated with a job with `parallelism = 1` are recreated by the job controller honoring exponential backoff delay again. However, for jobs with `parallelism > 1`, pods might be created without exponential backoff delay. ([#115021](https://github.com/kubernetes/kubernetes/pull/115021), [@nikhita](https://github.com/nikhita)) [SIG Apps]

- Fixes a problem with 63-second or 1-second connection delays with some VXLAN-based
  network plugins which was first widely noticed in 1.16 (though some users saw it
  earlier than that, possibly only with specific network plugins). If you were previously

* GCE: Fixes ILB creation on automatic networks with manually created subnetworks. ([#57351](https://github.com/kubernetes/kubernetes/pull/57351), [@nicksardo](https://github.com/nicksardo))
