The Cluster API effort is currently undergoing a complete rehaul of the existing codebase, moving off Terraform and into using govmomi directly.

### SIG-windows

- Fixed attaching volumes after detach errors. Now volumes that failed to detach are not treated as attached, Kubernetes will make sure they are fully attached before they can be used by pods. ([#120595](https://github.com/kubernetes/kubernetes/pull/120595), [@jsafrane](https://github.com/jsafrane)) [SIG Apps and Storage]

* Docker versions 1.10.3, 1.11.2, 1.12.6 have been validated

    * Docker version 1.12.6 known issues

        * overlay2 driver not fully supported

        * live-restore not fully supported

        * no shared pid namespace support

    * Docker version 1.11.2 known issues

- Fix performance issue when creating large objects using SSA with fully unspecified schemas (preserveUnknownFields). ([#111915](https://github.com/kubernetes/kubernetes/pull/111915), [@aojea](https://github.com/aojea)) [SIG API Machinery, Architecture, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Storage...

   * the default config file is "e2e.yaml/toml/json/..." and the test starts when no such config is found (as before) but if -viper-config is used, the config file must exist
   * -viper-config can be used to select a file with full path, with or without file suffix
   * the csiImageVersion/Registry flags were renamed to storage.csi.imageVersion/Registry

  // The value will change as readiness probes keep executing. If no readiness
  // probes are specified, this field defaults to true once the container is
  // fully started (see Started field).
  //
  // The value is typically used to determine whether a container is ready to
  // accept traffic.
  optional bool ready = 4;

- Switch scheduler to generate the merge patch on pod status instead of the full pod ([#103133](https://github.com/kubernetes/kubernetes/pull/103133), [@marwanad](https://github.com/marwanad)) [SIG Scheduling]

- The `export` query parameter (inconsistently supported by API resources and deprecated in v1.14) is fully removed.  Requests setting this query parameter will now receive a 400 status response. ([#98312](https://github.com/kubernetes/kubernetes/pull/98312), [@deads2k](https://github.com/deads2k)) [SIG API Machinery, Auth and Testing]

- Finalizer Protection for Service LoadBalancers is now in GA (enabled by default). This feature ensures the Service resource is not fully deleted until the correlating load balancer resources are deleted. ([#85023](https://github.com/kubernetes/kubernetes/pull/85023), [@MrHohn](https://github.com/MrHohn))

- Fixed attaching volumes after detach errors. Now volumes that failed to detach are not treated as attached. Kubernetes will make sure they are fully attached before they can be used by pods. ([#120595](https://github.com/kubernetes/kubernetes/pull/120595), [@jsafrane](https://github.com/jsafrane))
