2.0.0b18 released

Version 2.0.0b18 has been released, fixing a couple of recently introduced bugs that made Potato unusable in certain circumstances (when run from a directory with a space in its name, or when trying to log on Linux), and some other issues. Apologies for the delay to those who reported the unusable bug, RL got in the way and this took me a lot longer to get out than I’d planned.
