Since the last post we found two more serious bugs that needed to be fixed, i.e. they couldn't be left to patch.
Unfortunately they were hard to fix, one took about 22 hours to fix, the other took about 10 hours, and I spent a few hours tiding up some other small issues.
So the bug list is empty again. We will give the update one more test overnight, and if no more serious bugs are found, I'll put it in to peer review tomorrow afternoon.
If any minor bugs are found, we can patch them later.
