Digging Into WordPress v3.4
by Chris Coyier
Jeff Starr has updated our co-authored book to cover the new things in WordPress 3.4, update various content, and update the ALL AJAX theme that comes with it.
This is the 10th update to the book. Pretty cool that there are people that bought they book nearly 3 years ago now who are still getting free updates.
