- LimitRange and Endpoints resources can be created via an update API call if the object does not already exist. When this occurs, an authorization check is now made to ensure the user making the API call is authorized to create the object. In previous releases, only an update authorization check was performed. ([#65150](https://github.com/kubernetes/kubernetes/pull/65150), [@jennybuc...

LIST calls into multiple smaller chunks. A client can specify a limit to the number of results to return. If more results exist, a token is returned that allows the client to continue the previous list call repeatedly until all results are retrieved.  The resulting list is identical to a list call that does not perform chunking, thanks to capabilities provided by etcd3.  This allows the server to use less memory and CPU when very large lists are returned. This feature is gated as APIListChunking...

- kube-apiserver: the `--runtime-config` flag now supports an `api/beta=false` value which disables all built-in REST API versions matching `v[0-9]+beta[0-9]+`. ([#84304](https://github.com/kubernetes/kubernetes/pull/84304), [@liggitt](https://github.com/liggitt))

- Kubeadm: the limitation that the 'ignorePreflightErrors' field can not be set to 'all' in kubeadm config file has been removed ([#119351](https://github.com/kubernetes/kubernetes/pull/119351), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

* MountPropagation feature is now beta. As a consequence, all volume mounts in containers are now `rslave` on Linux by default. To make this default work in all Linux environments the entire mount tree should be marked as shareable, e.g. via `mount --make-rshared /`. All Linux distributions that use systemd already have the root directory mounted as rshared and hence they need not do anything. In Linux environments...

returned that allows the client to continue the previous list call repeatedly until all results are retrieved.  The resulting list is identical to a list call that does not perform chunking thanks to capabilities provided by etcd3.  This allows the server to use less memory and CPU responding with very large lists.  This feature is gated as APIListChunking and is not enabled by default.  The 1.9 release will begin using this by default from all informers. ([#48921](https://github.com/kubernetes/kubernetes/pull/48921),...
