- When proxying to an aggregated API server, kube-apiserver used the
  `EndpointSlices` of the `service` indicated by the `APIServer`, rather than
  using Endpoints.
  
  If you were using the aggregated API server feature, and you were writing out
  the endpoints for it by hand (rather than letting kube-controller-manager

- Removed the `KUBECTL_OPENAPIV3_PATCH` environment variable, as aggregated discovery has been stable since `v1.30`. ([#134130](https://github.com/kubernetes/kubernetes/pull/134130), [@ardaguclu](https://github.com/ardaguclu))

- The `RemoteRequestHeaderUID` feature moves to beta and is now enabled by default. This makes the kube-apiserver propagate UIDs in the `X-Remote-Uid` header in requests to the aggregated API servers. The header is not honored by default for incoming requests, but that can be enabled by setting the `--requestheader-uid-headers` flag explicitly.

- Added: Log Line for Debugging possible merge errors for kubelet related Config requests. ([#124389](https://github.com/kubernetes/kubernetes/pull/124389), [@holgerson97](https://github.com/holgerson97))
- Aggregated Discovery v2beta1 fixture is removed in `./api/discovery`. Please use v2 ([#127008](https://github.com/kubernetes/kubernetes/pull/127008), [@Jefftree](https://github.com/Jefftree)) [SIG API Machinery]
