[hpopp]

Added

• Support for Elixir 1.20 and Erlang/OTP 29. (#310)
• Dispatchers reconnect on their own when a connection drops. (#299, #300, #311)
• :not_connected push response. You get it when the dispatcher has no connection
  at the moment you push. The push was never sent, so it is safe to send again.
  :timeout still means the push went out but the connection dropped before a reply
  came back. (#311)
• FCM connections stay alive with periodic pings, the same way APNS connections
  already did. Tune it with the new :ping_period option. (#311)

Changed

• Dispatchers now connect in the background after they start. If the push service is
  unreachable, the dispatcher logs an error and keeps retrying instead of taking your
  app down with it. (#295, #309, #311)

  Removed

  • Stale :httpoison and :kadabra entries in mix.lock. (#305)

  Fixed

  • ADM no longer crashes the dispatcher when it cannot refresh its access token. The
    push gets a :not_connected response instead. (#311)
