connections.** Stale or canceled connections were incorrectly attempted when they shouldn't have
been, leading to rare cases of infinite retries. Please upgrade to this release!

 *  Fix: don't return stale DNS entries in `DnsOverHttps`. We were caching DNS results indefinitely
    rather than the duration specified in the response's cache-control header.

 *  Fix: Don't crash with a "cache is closed" error when there is an error initializing the cache.
 *  Fix: Calling `disconnect()` on a connecting `HttpUrlConnection` could cause it to retry in an
    infinite loop! This regression was introduced in OkHttp 2.7.0.
 *  Fix: Drop cookies that contain ASCII NULL and other bad characters. Previously such cookies
    would cause OkHttp to crash when they were included in a request.

   * way to ensure that a symbolic link to a directory is not followed when traversing the tree. In
   * this case, iterables created by this traverser could contain files that are outside of the
   * given directory or even be infinite if there is a symbolic link loop.
   *
   * <p>If available, consider using {@link MoreFiles#fileTraverser()} instead. It behaves the same
   * except that it doesn't follow symbolic links and returns {@code Path} instances.
