- Added a CBOR implementation of `runtime.Serializer`. Until CBOR graduates to Alpha, API servers will refuse to start if configured with CBOR support. ([#122881](https://github.com/kubernetes/kubernetes/pull/122881), [@benluddy](https://github.com/benluddy))
- Added a alpha feature, behind the `RelaxedEnvironmentVariableValidation` feature gate.

- Events reported for container creation, start, and stop now report the container name in the message and are more consistently formatted. ([#73892](https://github.com/kubernetes/kubernetes/pull/73892), [@smarterclayton](https://github.com/smarterclayton))

Version names are used to compute the order in which served versions are listed in API discovery. If the version string is \"kube-like\", it will sort above non \"kube-like\" version strings, which are ordered lexicographically. \"Kube-like\" versions start with a \"v\", then are followed by a number (the major version), then optionally the string \"alpha\" or \"beta\" and another number (the minor version). These are sorted first by GA > beta > alpha (where GA is a version with no suffix such as beta...

* Fix issue where on re-registration of device plugin, `allocatable` was not getting updated. This issue makes devices invisible to the Kubelet if device plugin restarts. Only work-around, if this fix is not there, is to restart the kubelet and then start device plugin.

# v1.10.2

* kubeadm now detects the Docker cgroup driver and starts the kubelet with the matching driver. This eliminates a common error experienced by new users in when the Docker cgroup driver is not the same as the one set for the kubelet due to different Linux distributions setting different cgroup drivers for Docker, making it hard to start the kubelet properly.
