Unknown. I have too much work that's higher priority than Beancount over the last couple of years and too many other higher priority items to make meaningful progress on new features for v3 so far. Much of the codes I wanted to fork out of it have been moved to other projects, so that's progress of a kind. On the status of new things: there's a new parser, the next step is I want to figure out how to properly link and expose the protobufs to Python (there are 2-3 ways that aren't great, and one good way to do it, I prototyped but haven't hooked it up yet), and to then replace the parser component with the newer, better C++ parser that's largely done, carefully comparing the old parser's output with the new.
