Today, the latest upgrade to WordPress was released, with the version number 2.5.1. This upgrade contains important security fixes and it’s strongly recommended that you upgrade your WordPress installation. You can choose to fix the security issues, only or take the whole package, for a complete upgrade. I did the complete upgrade, and it took just around 5 minutes and was really easy to accomplish.

Some of the bug fixes are, performance improvements, Fixes to the media uploader, and upgrade of TinyMCE to version 3.0.7, widgets fixes, layout fixes for Internet Explorer, and much more.
