### Bug Fixes and Other Changes

* `tf.data`
    * Add optional `synchronous` argument to `map`, to specify that the `map` should run synchronously, as opposed to be parallelizable when `options.experimental_optimization.map_parallelization=True`. This saves memory compared to setting `num_parallel_calls=1`.

* Add Priority admission controller for monitoring and resolving PriorityClasses. ([#49322](https://github.com/kubernetes/kubernetes/pull/49322), [@bsalamat](https://github.com/bsalamat))
* apiservers: add synchronous shutdown mechanism on SIGTERM+INT ([#50439](https://github.com/kubernetes/kubernetes/pull/50439), [@sttts](https://github.com/sttts))
