WordPress 3.4 (“Green” for jazz master Grant Green) is now released with some great new features.

It has some significant improvements on the ability to customize themes, custom headers, Twitter embed functionality, and a nice image caption capability. I recommend you upgrade to WordPress 3.4 as soon as possible.
