WordPress 2.3 is out for a while. For the past 4 months I have been using WordPress 2.1.3 for Typpz Blog. After extended back-ups (database export, contenet files etc) and plug-in deactivation, I updated the blog to WordPress 2.3.1! All plug-ins worked after reactivation, except the post listing plugin which is listed in the WordPress site as non-compatible with the latest version of the blogging platform and the ultimate tag warrior which in not needed as the new WordPress comes with built-in tag support. Tags were not imported as they should from Ultimate tag warrior, so I have to tag my posts again.
I have to say that the blog now corresponds much faster. I also liked the update notifications for new versions of the installed plugins. I recommend to everyone to upgrade to WordPress 2.3. Remember before upgrading: Backup, Backup, Backup (few clicks can save your blog in case something goes the wrong 😉 ).
