There's still some open discussion about how to do automatic updates (e.g. #1455). But I don't want to block the other valuable bug fixes already ready-to-go in 0.9.13. So, for .13 turn off automatic update checking completely (like .12) and defer it to .14 when these issues are ironed out.
Bumped back again, still because of #1455.
Script update checking on by default.
