where <code>P</code> is a type parameter and <code>C</code>
its corresponding constraint, the unification rules are bit
more complicated:

<ul>
<li>
	If <code>C</code> has a <a href="#Core_types">core type</a>
	<code>core(C)</code>
	and <code>P</code> has a known type argument <code>A</code>,
	<code>core(C)</code> and <code>A</code> must unify loosely.
	If <code>P</code> does not have a known type argument

  optional string volumeID = 1;

  // fsType is the filesystem type of the volume that you want to mount.
  // Tip: Ensure that the filesystem type is supported by the host operating system.
  // Examples: "ext4", "xfs", "ntfs". Implicitly inferred to be "ext4" if unspecified.

volume availability, the API now enables volume resizing and snapshotting. These features are in alpha.
The SIG also focused on providing more control over storage: the ability to set requests and
limits on ephemeral storage, the ability to specify mount options, more metrics, and improvements to Flex driver deployments.

## Before Upgrading

- `GetPodQOS(pod *core.Pod)` function now returns the stored value from `PodStatus.QOSClass`, if set. To compute/evaluate the value of `QOSClass` from scratch, `ComputePodQOS(pod*core.Pod)` must be used.

In some cases, for pure data validation and processing, you can get performance improvements of **20x** or more. This means 2,000% or more. 🤯

- k8s.io/kube-openapi: 591a79e → 3cc51fd

- Refactored `test/e2e/framework` so that the core framework is smaller. Optional functionality like resource monitoring, log size monitoring, metrics gathering and debug information dumping must be imported by specific e2e test suites. Init packages are provided which can be imported to re-enable the functionality that traditionally was in the core framework. If you have code that no longer compiles because of this PR, you can use the script [from...
