 * <p><strong>Cycle Detection</strong>
 *
 * <p>Deadlocks can arise when locks are acquired in an order that forms a cycle. In a simple
 * example involving two locks and two threads, deadlock occurs when one thread acquires Lock A, and
 * then Lock B, while another thread acquires Lock B, and then Lock A:

* `kubectl auth reconcile` only works with rbac.v1; all the core helpers have been switched over to use the external types. ([#63967](https://github.com/kubernetes/kubernetes/pull/63967), [@deads2k](https://github.com/deads2k))

		nr, nbytes, err := buf.ReadRune()

    characters it escapes. Previously we weren’t percent-encoding commas,
    parens, and other characters.
 *  Fix: Relax `FormEncodingBuilder` to support building empty forms.
 *  Fix: Timeouts throw `SocketTimeoutException`, not `InterruptedIOException`.
 *  Fix: Change `MockWebServer` to use the same logic as OkHttp when determining
    whether an HTTP request permits a body.

   *   <li>idempotence: {@code a.canonical(domain).canonical(domain).equals(a.canonical(domain))}
   * </ul>

   * <p>Furthermore, this method guarantees that the range returned will be one of the following
   * canonical forms:
   *
   * <ul>
   *   <li>[start..end)
   *   <li>[start..+∞)
   *   <li>(-∞..end) (only if type {@code C} is unbounded below)
   *   <li>(-∞..+∞) (only if type {@code C} is unbounded below)
   * </ul>

 *  Fix: Don't call `toDuration()` which isn't available in kotlin-stdlib 1.4.


## Version 5.0.0-alpha.8

_2022-06-08_

 *  Fix: Change how `H2_PRIOR_KNOWLEDGE` works with HTTP proxies. Previously OkHttp assumed the
    proxy itself was a prior knowledge HTTP/2 server. With this update, OkHttp attempts a `CONNECT`
