In case you haven't heard, Automattic, the company that owns WordPress and bbPress (and I have absolutely no affiliation other than independently running the software and writing a few plugins for myself) has acquired a huge cash investment.
So they are now promising big/fast code improvements to bbPress, including some spinoff projects aka BackPress and TalkPress.
I'm still figuring out what it all means myself, but you can read all these for more:

Meanwhile I can only promise that I will try to keep my plugins working through build 1075. I need to see how drastically their changes breaks my work and if the project will fork (or not).
Here's a video of Matt talking about BackPress and TalkPress
