Very stable here to, only really nasty bug I've found is with bit bridged plugins crashing and causing the project to get truncated.. as in next time you load it, it's done for.
Luckily I had backups, but a crash killing the project file is something that shouldn't happen.
It's not being unstable that's bugging me (har) but the bugs.. of which there's a lot lurking in the shadows waiting to bite ya.
Hoping next update squashes most of them.
