- Fixed a `v1.28` regression handling negative index json patches. ([#120327](https://github.com/kubernetes/kubernetes/pull/120327), [@liggitt](https://github.com/liggitt))

### Feature

- Added Windows support for the node memory manager. ([#128560](https://github.com/kubernetes/kubernetes/pull/128560), [@marosset](https://github.com/marosset)) [SIG Node and Windows]
- Added `--concurrent-daemonset-syncs` command line flag to kube-controller-manager. This value sets the number of workers for the daemonset controller. ([#128444](https://github.com/kubernetes/kubernetes/pull/128444), [@tosi3k](https://github.com/tosi3k))

### Bug or Regression

- Fix OpenAPI v3 not being cleaned up after deleting APIServices ([#120108](https://github.com/kubernetes/kubernetes/pull/120108), [@tnqn](https://github.com/tnqn)) [SIG API Machinery and Testing]
- Fix a concurrent map access in TopologyCache's `HasPopulatedHints` method. ([#120323](https://github.com/kubernetes/kubernetes/pull/120323), [@Miciah](https://github.com/Miciah)) [SIG Apps and Network]

- Enabled concurrent log rotation in kubelet. You can now configure the maximum number of concurrent rotations with the `containerLogMaxWorkers` setting, and adjust the monitoring interval with `containerLogMonitorInterval`.

### Bug or Regression

- EndpointSlice Mirroring controller now cleans up managed EndpointSlices when a Service selector is added (#106136, @robscott) [SIG Apps, Network and Testing]
- Fix concurrent map access causing panics when logging timed-out API calls. (#106124, @marseel) [SIG API Machinery]
- Support more than 100 disk mounts on Windows (#105673, @andyzhangx) [SIG Storage and Windows]

## Dependencies

- Aadjusted http/2 buffer sizes for apiservers to prevent starvation issues between concurrent streams ([#67902](https://github.com/kubernetes/kubernetes/pull/67902), [@liggitt](https://github.com/liggitt))

- Fix a panic in kubectl when creating secrets with an improper output type (#106354, @lauchokyip) [SIG CLI]
- Fix concurrent map access causing panics when logging timed-out API calls. (#106113, @marseel) [SIG API Machinery]
- Fixed very rare volume corruption when a pod is deleted while kubelet is offline.
