Alright, I've pushed up the latest to master, which includes fixes for the latest Discourse. I'll continue to maintain a beta branch going forward, but for now beta and master are the same.
This is a pretty major refactor, which will allow for a much better user experience for you and a much better dev experience for me going forward . The major feature in this release is that more than one chat can now be present on page at a time, which means that we can toggle both full page and shoutbox modes, which can now work together or independently. This will also allow us to integrate private messaging and quick messages-style channels in the future.
I also have the guts for a 'Who's online' feature in there, which I'll pull out into the interface soon, as well as chipping away at any regressions I hear about.
The language has also changed some in this release, so if you're a translator I'd appreciate some help getting that part back up to speed as well.
Thanks again for your patience, my day job has been (and will be) quite full-on for the recent past and near future, but I'm committed to keeping this project afloat as best I can.
I appreciate the offers of support and will be putting a donate link up onto the README shortly.
