- Fixed attaching volumes after detach errors. Now volumes that failed to detach are not treated as attached, Kubernetes will make sure they are fully attached before they can be used by pods.

    Potential impacts:

- [`KT-57845`](https://youtrack.jetbrains.com/issue/KT-57845) K2. Unresolved reference error on calling Java references with fully qualified name
- [`KT-58757`](https://youtrack.jetbrains.com/issue/KT-58757) K2: False-positive NON_PUBLIC_CALL_FROM_PUBLIC_INLINE error in case an inline fun is protected and is a part of an internal abstract class declaration

 the apps/v1beta1 API in this release, but you should start planning for code

 - Extended Resources are fully-qualified resource names outside the
 `kubernetes.io` domain. Extended Resource quantities must be integers.
 You can specify any resource name of the form `[aaa.]my-domain.bbb/ccc`

### SIG-windows

* kube-apiserver: the `Priority` admission plugin is now enabled by default when using `--enable-admission-plugins`. If using `--admission-control` to fully specify the set of admission plugins, the `Priority` admission plugin should be added if using the `PodPriority` feature, which is enabled by default in 1.11.
