- Text logging in Kubernetes components now uses [textlogger](https://pkg.go.dev/k8s.io/klog/v2@v2.120.0/textlogger). The same split streams of info and error log entries with buffering of info entries is now also supported for text output (off by default, alpha feature). Previously, this was only supported for JSON. Performance is better also without split streams. ([#114672](https://github.com/kubernetes/kubernetes/pull/114672), [@pohly](https://github.com/pohly))

* fluentd config for GKE clusters updated: detect exceptions in container log streams and forward them as one log entry. ([#39656](https://github.com/kubernetes/kubernetes/pull/39656), [@thomasschickinger](https://github.com/thomasschickinger))

- SSA treats certain structs as atomic ([#100684](https://github.com/kubernetes/kubernetes/pull/100684), [@Jefftree](https://github.com/Jefftree)) [SIG API Machinery, Auth, Node and Storage]

* Fixed missing error checking that could cause kubelet to crash in a race condition. ([#60962](https://github.com/kubernetes/kubernetes/pull/60962), [@technicianted](https://github.com/technicianted))
* Introduced `--http2-max-streams-per-connection` command line flag on api-servers and set default to 1000 for aggregated API servers. ([#60054](https://github.com/kubernetes/kubernetes/pull/60054), [@MikeSpreitzer](https://github.com/MikeSpreitzer))

- Added a return value to `QueueingHint` to indicate an error. If `QueueingHint` returns an error,
  the scheduler logs it and treats the event as a `QueueAfterBackoff` so that
  the Pod won't be stuck in the unschedulable pod pool. ([#119290](https://github.com/kubernetes/kubernetes/pull/119290), [@carlory](https://github.com/carlory))
