WordPress 2.0 has been released, its got lots of new features, but as far as I can tell they are all on the author side, not the reader. A full list of the changes is available over on the asymptomatic blog. There is a bit of AJAX in the interface as well, they could use it remove a couple more dialog popups, but editing is much cleaner now. If your running wordpress and are looking to upgrade there is a good article in the support forums walking you through the process.
The release process seems a bit odd though, the files exist, the website is updated, but there isn’t even an blog post announcing the release.
I’m also using the new akismet anti-spam plugin, I hope its good since they force you to create a blog at wordpress.com to use it.
Offical wordpress 2.0 release announcement is out, has the complete feature summary.
