The recent crashes
You may have noticed that PS has been crashing a lot recently.
PS runs on Node.js, and the newer versions aren't particularly stable and crash a lot. We used to run an old version to avoid that, but it's so old that it's not supported anymore, which means no security updates and some tools have stopped working.
So the new plan is to update to the newest version and fix those problems myself, but sometimes things crash. Sorry! But the good news is, we're making lots of progress so you should see much more stability in the future.
