They've added support for HTML5 WebM. Sped it up a bit.
Fixed issues surrounding various popular skins that were present all through the 10.5x range.
Voice finally works again (last heard in version 9.63!!!)
They still haven't fixed the IRC client, it is as borked as it ever was since the move to presto.
Oh and broken moobunny - you can't post any more. :p
