- Decoupled `TaintManager` from `NodeLifeCycleController` (KEP-3902). ([#119208](https://github.com/kubernetes/kubernetes/pull/119208), [@atosatto](https://github.com/atosatto))
- Enabled traces for KMSv2 encrypt/decrypt operations. ([#121095](https://github.com/kubernetes/kubernetes/pull/121095), [@aramase](https://github.com/aramase))

  correctly with an external cloud provider. ([#124516](https://github.com/kubernetes/kubernetes/pull/124516), [@danwinship](https://github.com/danwinship))
- Fixed an issue that prevents the linking of trace spans for requests that are proxied through kube-aggregator. ([#124189](https://github.com/kubernetes/kubernetes/pull/124189), [@toddtreece](https://github.com/toddtreece))

- Fixes regression in logging spurious stack traces when proxied connections are closed by the backend ([#82588](https://github.com/kubernetes/kubernetes/pull/82588), [@liggitt](https://github.com/liggitt))

- Resolves issue with `/readyz` and `/livez` not including etcd and kms health checks ([#82713](https://github.com/kubernetes/kubernetes/pull/82713), [@logicalhan](https://github.com/logicalhan))

- Trace output in apiserver logs is more organized and comprehensive. Traces are nested, and for all non-long running request endpoints, the entire filter chain is instrumented (e.g. authentication check is included). ([#88936](https://github.com/kubernetes/kubernetes/pull/88936), [@jpbet...

- Pod termination will be faster when the pod has a missing volume reference. ([#117412](https://github.com/kubernetes/kubernetes/pull/117412), [@smarterclayton](https://github.com/smarterclayton)) [SIG Node and Testing]

- API Server tracing can now trace re-entrant api requests. ([#103218](https://github.com/kubernetes/kubernetes/pull/103218), [@dashpole](https://github.com/dashpole)) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle and Instrumentation]

- `client-go`, using log level 9, traces the following events of a HTTP request:
      - DNS lookup
      - TCP dialing
      - TLS handshake
      - Time to get a connection from the pool
