I am, slowly, working on version 2.5. At the moment it isn't introducing a whole lot of new things but fixes a few bugs, and changes a few things to work better (better password security, for example). Not to mention eliminates a few annoying ways that people can stall battles/troll the channel.
I don't know when it'll be officially released though. Just keep an eye out for it, if you're still enjoying this game. :)
