- Removed the function Parallelize, please convert to use the function ParallelizeUntil. ([#76595](https://github.com/kubernetes/kubernetes/pull/76595), [@danielqsj](https://github.com/danielqsj))

### Apps

* Replace Parallelize with function ParallelizeUntil and formally deprecate the Parallelize. ([#68403](https://github.com/kubernetes/kubernetes/pull/68403), [@wgliang](https://github.com/wgliang))
