- 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),...

### Scalability

* Added the ability to limit the increase in apiserver memory usage when audit logging with buffering is enabled. ([#61118](https://github.com/kubernetes/kubernetes/pull/61118), [@shyamjvs](https://github.com/shyamjvs))

- JSON log output is configurable and now supports writing info messages to stdout and error messages to stderr. Info messages can be buffered in memory. The default is to write both to stdout without buffering, as before. ([#104873](https://github.com/kubernetes/kubernetes/pull/104873), [@pohly](https://github.com/pohly))

- The NodeAffinity plugin implements the PreFilter extension, offering enhanced performance for Filter. ([#99213](https://github.com/kubernetes/kubernetes/pull/99213), [@AliceZhang2016](https://github.com/AliceZhang2016)) [SIG Scheduling]
