WordPress 2.5 is out. It installed cleanly on my development site, but the flickr manager plugin seemed to hang. Eventually I worked out that there was an update available for it which hadn’t been announced and that seemed to solve the problem, so a quick
svn sw http://svn.automattic.com/wordpress/tags/2.5/ later and everything was upgraded cleanly.
The newly redesigned admin pages take a bit of getting used to, everything isn’t quite where I expect it to be, but I assume I’ll get used to it fairly quickly. The new dashboard view is better now that it includes a stats widget.
