 - Default `StreamingProxyRedirects` to disabled. If there is a >= 2 version skew between master and nodes, and the old nodes were enabling `--redirect-container-streaming`, this will break them. In this case, the `StreamingProxyRedirects` can still be manually enabled. ([#101647](https://github.com/kubernetes/kubernetes/pull/101647), [@pacoxu](https://github.com/pacoxu))

- Handle slow CronJob lister in CronJob controller v2 and improve memory footprint. ([#96443](https://github.com/kubernetes/kubernetes/pull/96443), [@alaypatel07](https://github.com/alaypatel07)) [SIG Apps]
- --redirect-container-streaming is no longer functional. The flag will be removed in v1.22 ([#95935](https://github.com/kubernetes/kubernetes/pull/95935), [@tallclair](https://github.com/tallclair)) [SIG Node]

- Faster mount detection for linux kernel 5.10+ using openat2 speeding up pod churn rates. On Kernel versions less 5.10, it will fallback to using the original way of detecting mount points i.e by parsing /proc/mounts.

* Add fallbacks to ARM API when getting empty node IP from Azure IMDS ([#69077](https://github.com/kubernetes/kubernetes/pull/69077), [@feiskyer](https://github.com/feiskyer))
* Deduplicate PATH items when reading plugins. ([#69089](https://github.com/kubernetes/kubernetes/pull/69089), [@soltysh](https://github.com/soltysh))

CustomResourceDefinitions also have new support for defaulting, with defaults specified using the `default` keyword in the OpenAPI validation schema. Defaults are set for unspecified fields in an object sent to the API, and when reading from etcd.

Defaulting will be available as alpha in Kubernetes 1.15 and requires structural schemas.

- Fixed file permission issues that happened during update of Secret/ConfigMap/projected volume when fsGroup is used. The problem caused a race condition where application gets intermittent permission denied error when reading files that were just updated, before the correct permissions were applied.
