WordPress 2.0 Plugins
The users of WordPress 2.0 Beta have put up a Wiki page to allow everyone to post which plugins are still working and which ones are breaking in the new WordPress version. It looks like many plugins will not need any update at all to continue doing what they do best, enhance WordPress.
One of the ones that do not work is the Tiger Administration Plugin, but last I heard Steve Smith of OrderedList (the creator) is looking to have it ready for the full WordPress 2.0 release, so don’t worry if some of your favourites don’t work as the community will fix them, and what I have heard from most people is that the fixes are usually quite simple.
