#### kubectl:
- the boolean and unset values for the --dry-run flag are deprecated and a value --dry-run=server|client|none will be required in a future version. ([#87580](https://github.com/kubernetes/kubernetes/pull/87580), [@julianvmodesto](https://github.com/julianvmodesto)) [SIG CLI]

* addon-resizer flapping behavior was removed. ([#46850](https://github.com/kubernetes/kubernetes/pull/46850), [@x13n](https://github.com/x13n))
* Change default `httpGet` probe `User-Agent` to `kube-probe/<version major.minor>` if none specified, overriding the default Go `User-Agent`. ([#47729](https://github.com/kubernetes/kubernetes/pull/47729), [@paultyng](https://github.com/paultyng))

    * --alpha-endpoint-reconciler-type=(master-count, lease, none) (default
    * "master-count"). The original reconciler is 'master-count'. The 'lease'
    * reconciler uses the storageapi and a TTL to keep alive an endpoint within the
    * `kube-apiserver-endpoint` storage namespace. The 'none' reconciler is a noop
    * reconciler that does not do anything. This is useful for self-hosted

"HostToContainer" as a default caused regressions in some pods. ([#62462](https://github.com/kubernetes/kubernetes/pull/62462), [@jsafrane](https://github.com/jsafrane))

### Changed

* Default mount propagation has changed from `HostToContainer` ("rslave" in Linux terminology), as it was in 1.10, to `None` ("private") to match the behavior in 1.9 and earlier releases; `HostToContainer` as a default caused regressions in some pods. If you are relying on this behavior you will need to set it explicitly. ([#62462](https://github.com/kubernetes/kubernetes/pull/62462),...
