Version 2.5.1 of WordPress is now available.

It contains an important security fix and about 70 bug fixes, along with other performance improvements.

Here are some important changes:

• Performance improvements for the Dashboard, Write Post, and Edit Comments pages.
• Better performance for those who have many categories
• Media Uploader fixes
• An upgrade to TinyMCE 3.0.7
• Widget Administration fixes
• Various usability improvements
• Layout fixes for IE

It’s important that everyone running WordPress upgrade to this new version. I will do so during the day. Remember to backup everything first, and if you have the chance, test it locally .
