I’m all about major upgrades. Did you know that Wordpress has received almost 2 Million downloads since 2.3 was released? Wordpress is free, easy to use, but most important, stable. Since Wordpress has become such a widely used Content Management System (CMS), the coders on the dark side are always trying to breach its security to take advantage of people’s websites. So, here is 2.5 to keep up with the security issues, as well as a few more features the Wordpress team added.
If you’re upgrading: ALWAYS backup your MySQL database and your Wordpress directory files.
WordPress 2.5, the culmination of six months of work by the WordPress community, people just like you. The improvements in 2.5 are numerous, and almost entirely a result of your feedback: multi-file uploading, one-click plugin upgrades, built-in galleries, customizable dashboard, salted passwords and cookie encryption, media library, a WYSIWYG that doesn’t mess with your code, concurrent post editing protection, full-screen writing, and search that covers posts and pages.
