Synapse 0.3.4 is out! The main changes here are a huge fleet of bugfixes to the webclient, and the addition of TURN support for VoIP relaying. This makes VoIP/Video call setup much more reliable (although the UI still needs some love).
Meanwhile, we set an IRC bridge (https://github.com/tm604/Matrix-IRCBridge) running linking #matrix:matrix.org and #matrix-dev:matrix.org to their Freenode counterparts (#matrix & #matrix-dev respectively) - much fun to see innocent IRC users assimilated up into Matrix, and for us to now be using Matrix for /all/ our development chat and interaction (whether it's through a Matrix client or an IRC client).
To upgrade to the latest homeserver, just
git pull && ./synctl restart. If you want to start playing with VoIP in earnest on your own homeserver, you'll need to install a TURN server - see docs/turn-howto.rst for details on how to set one up.
http://matrix.org/alpha has already been upgraded to 0.3.4, so feel free to play with all the new stuff there.
This version adds support for using a TURN server. See docs/turn-howto.rst on how to set one up.
