WordPress 3.0 was released today. I upgraded a handful of installations and it went smoothly for the most part. I did get an error message related to http.php

But following a tip here I disabled my plugins and ran the upgrade. Then I re-enabled the plugins. Other than that everything went smoothly.

The new features they’ve added (and bug fixes) are great. WordPress was already a powerful CMS and blogging platform, but 3.0 is even more polished. The new default Twenty Ten theme is a huge improvement over the old default themes and it’s easily customized without touching a line of code. I’ve switched this blog back to the default for now so I can have an out-of-box experience.

It’s pretty brilliant that you can upgrade WordPress from within a single browser window, and the upgrade takes maybe 15 seconds. This is on a system with a highly customized theme and a dozen plugins installed. Everything is so simple even a non-techie can figure it out. Compare that to a Microsoft SharePoint installation/upgrade which can take hours at best. Nice work WordPress guys!
