This release features a major upgrade to how the app communicates with the relay, in essence switching from each game communicating individually (and only when open) to the app communicating on behalf of all games. You should notice only that moves are transmitted more reliably. But this being new code you may also notice bugs. If you don't tell me about them they will not get fixed.
(The full changelog is here.)
Please remember that this is beta software. Please let me know (at eehouse@eehouse.org) what's broken and what features you'd most like to see.
Thanks!
