## Major Themes

Kubernetes is developed by community members whose work is organized into
[Special Interest Groups][]. For the 1.8 release, each SIG provides the
themes that guided their work.

### SIG API Machinery

* Fix mounting of UNIX sockets(and other special files) in subpaths ([#61480](https://github.com/kubernetes/kubernetes/pull/61480), [@gnufied](https://github.com/gnufied))

* Support new NODE_OS_DISTRIBUTION 'custom' on GCE ([#61235](https://github.com/kubernetes/kubernetes/pull/61235), [@yguo0905](https://github.com/yguo0905))
* Fix mounting of UNIX sockets(and other special files) in subpaths ([#61480](https://github.com/kubernetes/kubernetes/pull/61480), [@gnufied](https://github.com/gnufied))

  behind the `DynamicResourceAllocation` feature gate).

  level, or following any other model you implement.' ([#111023](https://github.com/kubernetes/kubernetes/pull/111023), [@pohly](https://github.com/pohly))

- `e2e.test` now rejects unknown `--provider` values instead of merely warning about them. An empty provider name is not accepted anymore and was replaced by `skeleton` (a provider with no special behavior). ([#73402](https://github.com/kubernetes/kubernetes/pull/73402), [@pohly](https://github.com/pohly))
- Updated to go1.11.5 ([#73326](https://github.com/kubernetes/kubernetes/pull/73326), [@ixdy](https://github.com/ixdy))

Remove the DockerValidor and ServiceCheck for the `docker` service from kubeadm preflight. Docker is no longer special cased during host validation and ideally this task should be done in the now external cri-dockerd project where the importance of the compatibility matters. Use `crictl` for all communication with CRI sockets for actions like pulling images and obtaining...
