matching. PathType can be one of the following values: * Exact: Matches the URL path exactly. * Prefix: Matches based on a URL path prefix split by '/'. Matching is\n  done on a path element by element basis. A path element refers is the\n  list of labels in the path split by the '/' separator. A request is a\n  match for path p if every p is an element-wise prefix of p of the\n  request path. Note that if the last element of the path is a substring\n  of the last element in request path, it is not...

Two alpha features were also added in this release.

The RuntimeClass alpha feature enables a node to surface multiple runtime options to support a variety of workload types.  Examples include native linux containers, and “sandboxed” containers that isolate the container from the host kernel.

  // If Selector is empty, it is defaulted to the labels present on the Pod template.
  // Label keys and values that must match in order to be controlled by this replication
  // controller, if empty defaulted to labels on Pod template.

- The `volume_zone` plugin will consider `beta` labels as `GA` labels during the scheduling
  process. Therefore, if the values of the labels are the same, PVs with `beta` labels
  can also be scheduled to nodes with `GA` labels. ([#118923](https://github.com/kubernetes/kubernetes/pull/118923), [@AxeZhan](https://github.com/AxeZhan))

*   Block Storage (Cinder) V3 is now supported.
*   Load Balancer (Octavia) V2 is now supported, in addition to Neutron LBaaS V2.
*   Neutron LBaas V1 support has been removed.
