This section provides an overview of deprecated API versions, options, flags, and arguments. Deprecated means that we intend to remove the capability from a future release. After removal, the capability will no longer work. The sections are organized by SIGs.

### Apps

- The `.spec.rollbackTo` field of the Deployment kind is deprecated in `extensions/v1beta1`.

- Kube-apiserver --help flag help is now printed in sections. ([#64517](https://github.com/kubernetes/kubernetes/pull/64517), [@sttts](https://github.com/sttts))

* Add per-pod scheduling metrics across 1 or more schedule attempts. ([#83674](https://github.com/kubernetes/kubernetes/pull/83674), [@liu-cong](https://github.com/liu-cong))
* Fix validation message to mention bytes, not characters. ([#80880](https://github.com/kubernetes/kubernetes/pull/80880), [@DirectXMan12](https://github.com/DirectXMan12))

- The feature gate was mentioned as `csiMigrationRBD` where it should have been `CSIMigrationRBD` to be in parity with other migration plugins. This release correct the same and keep it as `CSIMigrationRBD`.

### Bug or Regression

- Fixed in-tree to CSI migration for Portworx volumes, in clusters where Portworx security feature is enabled (it's a Portworx feature, not Kubernetes feature). It required secret data from the secret mentioned in-tree SC, to be passed in CSI requests which was not happening before this fix. ([#129674](https://github.com/kubernetes/kubernetes/pull/129674), [@gohilankit](https://github.com/gohilankit)) [SIG Storage]
