The recent changes to use a state file are buggy and cause some rather bizarre problems. But there's also the question of compatibility with older versions; I was reassured that the change *is* backward compatible, but if you aren't seeing parameters from a restart then either that or some other change is not backward compatible. (I've already had to rewire this once because of an unannounced non-backward-compatible change leading up to 0.12. I am not a fan of "move fast, break stuff" especially if the only way I can find out about it is to audit every single commit.)
