- Kubectl [get and describe](https://github.com/kubernetes/enhancements/issues/515) now works with extensions
- Nodes now support [third party monitoring plugins](https://github.com/kubernetes/enhancements/issues/606).
- A new [Scheduling Framework](https://github.com/kubernetes/enhancements/issues/624) for schedule plugins is now Alpha.

- Refactored `test/e2e/framework` so that the core framework is smaller. Optional functionality like resource monitoring, log size monitoring, metrics gathering and debug information dumping must be imported by specific e2e test suites. Init packages are provided which can be imported to re-enable the functionality that traditionally was in the core framework. If you have code...

- Added configurable per-device health check timeouts to the DRA health monitoring API. ([#135147](https://github.com/kubernetes/kubernetes/pull/135147), [@harche](https://github.com/harche)) [SIG Node]
