There's pressure being put on Gazelle right now because Waffles and AnimeBytes are writing a replacement called Batter[1] using Django. I've also been working on a tracker in Go called Chihaya[2] that will replace Ocelot. I'm glad they finally opening things up more, but it might be a bit too late. If you're interested in working on a more modern rewrite of Gazelle's software stack that has actual software development practices (continuous integration, tests, style guidelines), check out the projects. Both projects are BSD 2 Clause, btw.
What's the motivation for replacing Ocelot? My understanding is that it's mostly a drop-in replacement for XBTT (please correct me if I'm wrong); is one of the design goals of Chihaya to modernize the API?
It's only gofmt with lines <80 chars; there is a function call or two broken into multiple lines to meet that. I'm scrapping that limit and just going to make it as readable as possible. The real crazy thing is GitHub using 8 spaces for tabs!
