* Federation service controller is one key component of federation controller manager, it watches federation service, creates/updates services to all registered clusters, and update DNS records to global DNS server. ([#26034](https://github.com/kubernetes/kubernetes/pull/26034), [@mfanjie](https://github.com/mfanjie))

    to change, and the implementation is incomplete. This is a big new API we
    are eager for feedback.

 *  New: Support ALPN via Google Play Services' Dynamic Security Provider. This
    expands HTTP/2 support to older Android devices that have Google Play
    Services.
 *  New: Consider all routes when looking for candidate coalesced connections.
    This increases the likelihood that HTTP/2 connections will be shared.

     * * **Unreachable IP addresses.** If the URL's host has multiple IP addresses,
     *   failure to reach any individual IP address doesn't fail the overall request. This can
     *   increase availability of multi-homed services.
     *
     * * **Stale pooled connections.** The [ConnectionPool] reuses sockets
     *   to decrease request latency, but these connections will occasionally time out.
