Huh, I almost got stuck with this one. It's boring to do larger rewrites to things that already kind of work. This time it was rewriting how caching headers work.

The old way was kind of ugly and it didn't really guarantee the order in which cached headers could be fetched. So there were a few theoretical problems that could have broken things. 0.99.10 didn't support caching headers at all, so it didn't have this problem.

I think the new caching code is finally nearly finished. Just a few small things left and it's done.

This release also fixes some other crashes and problems. I've been running it nearly an hour now without problems :)
