- 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.

* Implement and update interfaces and skeleton for the scheduling framework. ([#75848](https://github.com/kubernetes/kubernetes/pull/75848), [@bsalamat](https://github.com/bsalamat))
* Fixes segmentation fault issue with Protobuf library when log entries are deeply nested. ([#77224](https://github.com/kubernetes/kubernetes/pull/77224), [@qingling128](https://github.com/qingling128))

* 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.

 the apps/v1beta1 API in this release, but you should start planning for code
 that does not depend on mutable selectors.

 - 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`

- Fix performance issue when creating large objects using SSA with fully unspecified schemas (preserveUnknownFields).

  // The value is typically used to determine whether a container is ready to
