- Added apiserver identity to the following metrics: 

show/hide actions based on the end user, and for users to quickly reason about their own permissions.

* [alpha] Building on the 1.7 work to allow encryption of resources such as secrets, a mechanism to store resource encryption keys in external Key Management Systems (KMS) was introduced. This complements the original file-based storage and allows integration with multiple KMS. A Google Cloud KMS plugin was added and will be usable once the Google side of the integration is complete....

- Changed how KMS v2 encryption at rest can generate data encryption keys.

* ✨ Add `description` parameter to all the security scheme classes, e.g. `APIKeyQuery(name="key", description="A very cool API key")`. PR [#1757](https://github.com/tiangolo/fastapi/pull/1757) by [@hylkepostma](https://github.com/hylkepostma).

- Fixed a regression in default 1.26 configurations, which enabled PodDisruptionConditions by default, 
  that prevented the control plane's pod garbage collector from deleting pods that contained duplicated field keys (env. variables with repeated keys or container ports).
