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

There are three kinds of compatibility we’re tracking:

 * **Binary compatibility** is the ability to compile a program against OkHttp 3.x, and then to run
   it against OkHttp 4.x. We’re using the excellent [japicmp][japicmp] library via its
   [Gradle plugin][japicmp_gradle] to enforce binary compatibility.

 * **Java source compatibility** is the ability to upgrade Java uses of OkHttp 3.x to 4.x without
   changing `.java` files.

    assertEquals(1, (int) iter.next());

    /*
     * We test peek() after various calls to make sure that one bad call doesn't interfere with its
     * ability to throw the correct exception in the future.
     */
    assertThrows(NoSuchElementException.class, iter::peek);

* Fix GCE etcd scripts to pass in all required parameters for the etcd migration utility to correctly perform HA upgrades and downgrades ([#61956](https://github.com/kubernetes/kubernetes/pull/61956), [@jpbetz](https://github.com/jpbetz))

Maven plugin execution isolation

 Maven2 takes advantage of Plexus' ability to execute a component using a
 ClassWorlds ClassRealm that is populated with the JAR containing the
 component in question and all of its dependencies. Using ClassWorlds
 notation for realms we have the following:

### SIG CLI introduces kubectl debug

However, this means that STS tokens signed previously by root credentials will no longer be valid upon upgrading to the latest version with this change. Please re-generate them as you usually do. Additionally,...
