After editing the OP of this thread to update proposals for future releases, I realised our guidance on what we're working on is woefully inefficient. We have this thread, this wiki page and GitHub issues - spread out, inconsistent and difficult for everyone to update. It's fair to say our plans for releases haven't exactly worked out anyway, since we just end up implementing whatever happens to have been completed rather than going somewhere more directed.
Should we try to reorganise ourselves to work towards decisive feature goals? I'm not saying we have to, but I think it should be considered. The next release seems to have a pretty solid planned features list already: UE4 conversion (if that works), combat mechanics, agents and organelle upgrades. I think @hhyyrylainen suggested a Trello board a while ago. While this could work, I'm sure there are better options which integrate more effectively with what the sprawling mass of internet presences we already have.
