- Fixed a performance issue applying json patches to deeply nested objects ([#93811](https://github.com/kubernetes/kubernetes/pull/93811), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle and Instrumentation]

A security issue was discovered in Kubernetes where users may have access to secure endpoints in the control plane network. Kubernetes clusters are only affected if an untrusted user can to modify Node objects and send requests proxying through them.

- NOTE ([#113749](https://github.com/kubernetes/kubernetes/pull/113749), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery]
- Nested `MountPoints` are now grouped correctly on all cases. ([#112571](https://github.com/kubernetes/kubernetes/pull/112571), [@claudiubelu](https://github.com/claudiubelu))

- 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).
