* MountPropagation feature is now beta. As a consequence, all volume mounts in containers are now `rslave` on Linux by default. To make this default work in all Linux environments the entire mount tree should be marked as shareable, e.g. via `mount --make-rshared /`. All Linux distributions that use systemd already have the root directory mounted as rshared and hence they need not do anything. In Linux environments without systemd we...

- Commands like `kubectl apply` now return errors if schema-invalid annotations are specified, rather than silently dropping the entire annotations section. ([#83552](https://github.com/kubernetes/kubernetes/pull/83552), [@liggitt](https://github.com/liggitt))

and is not guaranteed to be the same from one iteration to the next.
If a map entry that has not yet been reached is removed during iteration,
the corresponding iteration value will not be produced. If a map entry is
created during iteration, that entry may be produced during the iteration or
may be skipped. The choice may vary for each entry created and from one
iteration to the next.

- Kube-apiserver: regular expressions specified with the `--cors-allowed-origins` option are now validated to match the entire `hostname` inside the `Origin` header of the request and 
  must contain '^' or the '//' prefix to anchor to the start, and '$' or the port separator ':' to anchor to 

- Server Side Apply now treats LabelSelector fields as atomic (meaning the entire selector is managed by a single writer and updated together), since they contain interrelated and inseparable fields that do not merge in intuitive ways.

### Bug or Regression

- Consider only plugin directory and not entire kubelet root when cleaning up mounts ([#112920](https://github.com/kubernetes/kubernetes/pull/112920), [@mattcary](https://github.com/mattcary)) [SIG Storage]

* If a required flag is not provided to a command, the user will only see the required flag error message, instead of the entire usage menu. ([#86693](https://github.com/kubernetes/kubernetes/pull/86693), [@sallyom](https://github.com/sallyom))

- Volume mount cleanup now considers only plugin directory and not the entire kubelet root ([#112607](https://github.com/kubernetes/kubernetes/pull/112607), [@mattcary](https://github.com/mattcary))
- `kubectl` now escapes terminal special characters in output. This fixes CVE-2021-25743.
