- 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))

- Update Golang to v1.14.5
  - Update repo-infra to 0.0.7 (to support go1.14.5 and go1.13.13)
    - Includes:
      - bazelbuild/bazel-toolchains@3.3.2
      - bazelbuild/rules_go@v0.22.7 ([#93088](https://github.com/kubernetes/kubernetes/pull/93088), [@justaugustus](https://github.com/justaugustus)) [SIG Release and Testing]
- Update Golang to v1.14.6
  - Update repo-infra to 0.0.8 (to support go1.14.6 and go1.13.14)
    - Includes:

- 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),...

### Bug or Regression

* Use arm32v7|arm64v8 images instead of the deprecated armhf|aarch64 image organizations ([#50602](https://github.com/kubernetes/kubernetes/pull/50602), [@dixudx](https://github.com/dixudx))

pkg image, method (*RGBA64) SubImage(Rectangle) Image
pkg image, method (*Uniform) At(int, int) color.Color
pkg image, method (*Uniform) Bounds() Rectangle
pkg image, method (*Uniform) ColorModel() color.Model
pkg image, method (*Uniform) Convert(color.Color) color.Color
pkg image, method (*Uniform) Opaque() bool
pkg image, method (*Uniform) RGBA() (uint32, uint32, uint32, uint32)

- kube-controller-manager now uses the informer cache instead of active pod gets in HPA controller ([#68241](https://github.com/kubernetes/kubernetes/pull/68241), [@krzysztof-jastrzebski](https://github.com/krzysztof-jastrzebski))

- Restored `NumPDBViolations` info of nodes, when `HTTPExtender ProcessPreemption`. This info will be used in subsequent filtering steps - `pickOneNodeForPreemption` ([#105853](https://github.com/kubernetes/kubernetes/pull/105853), [@caden2016](https://github.com/caden2016))

- Extend kube-apiserver /readyz with new "informer-sync" check ensuring that internal informers are synced. ([#92644](https://github.com/kubernetes/kubernetes/pull/92644), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery and Testing]
