This includes adding the description of the changes to the `accepted-public-api-changes.json` file, and providing a reason for each change.
You can add the changes to any place in the file, e.g. at the top.

3. Make sure the file with accepted changes is sorted.\
Use the `./gradlew :architecture-test:sortAcceptedApiChanges` task to sort the file.

* Allow the system:heapster ClusterRole read access to deployments ([#48357](https://github.com/kubernetes/kubernetes/pull/48357), [@faraazkhan](https://github.com/faraazkhan))
* Ensure get_password is accessing a file that exists. ([#48351](https://github.com/kubernetes/kubernetes/pull/48351), [@ktsakalozos](https://github.com/ktsakalozos))

    *   Pod Security Policy can now manage access to specific FlexVolume drivers.([#53179](https://github.com/kubernetes/kubernetes/pull/53179),[ @wanghaoran1988](https://github.com/wanghaoran1988))
    *   To prevent unauthorized access to CHAP Secrets, you can now set the secretNamespace storage class parameters for the following volume types:

* Processing data:
    * For example, let's say you receive a file that must go through a slow process, you can return a response of "Accepted" (HTTP 202) and process the file in the background.
