Upgrade to WordPress 3.0

Apr 11, 2010 by Thomas

So today I took the plunge and upgraded to WordPress 3.0 Beta. Normally, I would wait, but the new features and the new default theme (Twenty Ten) intrigued me enough to throw caution to the wind.

Key features include:

a default theme that lends itself to child theme development
a menu system that allows you to mix categories and pages
better custom post types
a merged WP/WPMU code base, which allows managing a network of sites (multisite) without a separate WPMU installation
and a variety of code improvements and bug fixes

You can see a complete list of new features here.

Here is what I’ve learned so far during the install:

disable all plugins (just to be safe)
WooThemes would not work out of the box, so it is best if you first revert to the default theme (Kubrick). The site worked fine, but the theme caused an error in the admin section.

Experimenting with the new Menu system (based on the Woo Themes framework) is a delight!

very cool feature!
selecting pages and categories is simple
creating nested menus is as simple as dragging one item on top of the other
ordering menu items is a little tricky, just because the drag-and-drop Ajax control requires a steady hand
