### API Change

- A new alpha-level field, `SupportsFsGroup`, has been introduced for CSIDrivers to allow them to specify whether they support volume ownership and permission modifications. The `CSIVolumeSupportFSGroup` feature gate must be enabled to allow this field to be used. ([#92001](https://github.com/kubernetes/kubernetes/pull/92001), [@huffmanca](https://github.com/huffmanca)) [SIG API Machinery, CLI and Storage]

This is useful for operations that need to happen after a request, but that the client doesn't really have to be waiting for the operation to complete before receiving the response.

This includes, for example:

* Email notifications sent after performing an action:
    * As connecting to an email server and sending an email tends to be "slow" (several seconds), you can return the response right away and send the email notification in the background.

```

- A security fix must be backported if a customer is affected by it, we have a mechanism in SUBNET to send out notifications to affected customers in such situations, this is a mandatory requirement.
