0.10.0 posted that contains fixes to load into 2.1 (and a couple other cleanups). I want more time to understand some parts of the new fluid mechanics to see if I can get heat exchangers working again, but didn't want to hold up the release any more for that.
Also, while I've tested this against base game and a few mods, not all are updated to 2.1 yet, so there may be some gremlins still. Feel free to report bugs!
