Last night, I had the honor of taking the folks at the WordPress D.C. meetup group on a tour of the awesome new features of WordPress 3.6. Many, many thanks to Jorbin and Nacin for inviting me to do this. If you missed the meetup, the recording will appear on WordPress.tv soonish. You can also check out my slides, but since much of the presentation was demoing the features, the slide deck might seem a little thin.
But the best way of experiencing the new hotness in WordPress 3.6 is downloading the beta yourself, install it on a nice sandbox somewhere, and get to playing!
