Any time any type of software goes from one version number to the next, it is significant. WordPress 3.0 brings a few interesting highlights.
McLane Creative customers: You shouldn’t have any problems with the upgrade. All of the templates/sites I have out there are compliant and should upgrade just fine. To upgrade, open up your dashboard and click the “Upgrade to WordPress 3.0” link at the top of the screen.
If there are any problems, let me know.
If you have a WordPress stand-alone blog, I highly suggest upgrading immediately. With more than 1200 bug fixes, there is bound to be a security issue in there you’ll want cleaned up.
