Travelling sure makes it hard to keep updated on latest happenings. Just noticed that WordPress 2.2 was released couple of days ago and of course with all new software, there is always tiny problems that will occur.

Think I’ll probably hold off upgrading all the sites till a minor revision to the 2.2 branch is released.
