There’s just been a big update with a whole bunch of new stuff (and several bug fixes which the devs are fixing as quick as the community finds them!). The creatures of Boundless, as far as I know, will be one of the next things in the development pipeline.
Sorry I can’t give a more definitive answer than that!
Edit: Here’s the update thread with the big release info on it… Testing 22: Warps, Planets, and more!
Worth having a look at the other dev logs though so you can see what else has been updated since then!
