WordPress 2.0 was released on December 26 2005. Tonight I decided to take it for a spin. It was a fairly painless upgrade process. The big changes are hidden in the background code, but some nice things can be seen in the administration interface, like a WYSIWYG post editor, some AJAX-tweaks, a nice post preview function etc. Also, the Akismet spam prevention plugin is now built in from scratch. Some third party plugins may not work correctly after an upgrade, but you can always check the 2.0 Plugin Compatibility List before upgrading.
Check out this post on what’s new in 2.0.
