 *  **HTTP/2 support.** We've done interop testing and haven't seen any
    problems. HTTP/2 support has been a big effort and we're particularly
    thankful to Adrian Cole who has helped us to reach this milestone.

 *  **RC4 cipher suites are no longer supported by default.** To connect to
    old, obsolete servers relying on these cipher suites, you must create a
    custom `ConnectionSpec`.
