Yeah apparently my tickets have unearthed some actual bugs, so that's good they're working on them. (Open support tickets, people!). 

Being worked on for hotfixes:

- Area Render doesn't render the right area on Mac

- HSV nodes are ignored in Background and Queue renders

I'm not sure about the other issues (like if a figure uses hair strands at all, it really slows down preview, or body part welding is very sketchy unless you use Unimesh, and even then it can be easy to break), but it's good they're working on the main things and fingers crossed there'll be a service release pre-v14.
