WordPress 3.3, released on December 12th, is nicknamed Sonny, for jazz saxophonist, Sonny Stitt.

Honestly, I wasn’t too jazzed about Sonny when I immediately got a “Fatal error: Call to undefined function is_rtl()” message after the upgrade. Couldn’t even log into the Admin Panel. Grrr.

Fortunately, I wasn’t the only blogger who experienced this, so it was easy to find a solution to the WordPress 3.3 Fatal error installation problem.

After getting back into the Administration Panel and reading about the upgrades, I think the most beneficial change is the use of liquid layouts that will scale output to fit any screen size. In the age of increasing mobile media usage — this is a huge benefit.

Too, as someone who uploads a lot of pictures to my sites, I will also appreciate the drag-and-drop media uploader… once I figure out how it works. When I tried it, it opened up a new browser window to the location of the picture on my computer. Thought I’d lost my new post. That wasn’t the case but Hmmm…

The good folks at WordPress describe this iteration as having “significant polish around the new user experience, navigation, uploading, and imports.” There is a short video about Sonny on the WordPress site that summarizes the things they think you’ll find are the cat’s pajamas.

See the WordPress 3.3 release notes for a complete list of changes and new features.
