### Other (Cleanup or Flake)

- Added basic Denial Of Service prevention for the the node-local kubelet `podresource` API ([#116459](https://github.com/kubernetes/kubernetes/pull/116459), [@ffromani](https://github.com/ffromani)) [SIG Node and Testing]

  - the `--make-symlinks` flag, deprecated in v1.14, has been removed. ([#80017](https://github.com/kubernetes/kubernetes/pull/80017), [@Pothulapati](https://github.com/Pothulapati))

- kube-apiserver

  - the `--basic-auth-file` flag and authentication mode is deprecated and will be removed in a future release. It is not recommended for production environments. ([#81152](https://github.com/kubernetes/kubernetes/pull/81152), [@tedyu](https://github.com/tedyu))

- Certain `requestBody` parameters in the OpenAPI `v3` are now correctly marked as required. ([#120735](https://github.com/kubernetes/kubernetes/pull/120735), [@Jefftree](https://github.com/Jefftree))

        * Switch to basing our image of Elasticsearch in fluentd-elasticsearch addon off the official one
        * Switch to the official image of Kibana in fluentd-elasticsearch addon
        * Use StatefulSet for Elasticsearch instead of ReplicationController, with persistent volume claims
        * Require authenticating towards Elasticsearch, as Elasticsearch 5.5 by default requires basic authentication

- Added to `MutableFeatureGate` the ability to override the default setting of feature gates, to allow default-enabling a feature on a component-by-component basis instead of for all affected components simultaneously.
