  `How fond she is of finding morals in things!' Alice thought to
herself.

  `I dare say you're wondering why I don't put my arm round your

  - `resourceclaim_controller_creates_total` count metric with labels `admin_access` (true or false), `status` (failure or success) to track the total number of `ResourceClaims` creation requests

- DRA: The resource claim controller now maintains metrics about the total number of `ResourceClaims` and the number of allocated `ResourceClaims`. ([#127661](https://github.com/kubernetes/kubernetes/pull/127661), [@pohly](https://github.com/pohly)) [SIG Apps, Instrumentation and Node]

  - Speed up finding unneeded nodes by 5x+ in very large clusters by reducing the number of PreFilter calls
  - Expose `--max-nodes-total` as a metric
  - Errors in `IncreaseSize` changed from type `apiError` to `cloudProviderError`
  - Make `build-in-docker` and `test-in-docker` work on Linux systems with SELinux enabled

- Dynamic provisions that create iSCSI PVs can now ensure that multipath is used by specifying 2 or more target portals in the PV, which will cause kubelet to wait up to 10 seconds for the multipath device. PVs with just one portal continue to work as before, with kubelet not waiting for the multipath device and just using the first disk it finds. ([#67140](https:...
