So WordPress 3.4 has been out in the wild for a couple days now. Hopefully by now, you have any WordPress installs you manage up to date and running 3.4. How did your upgrade go? The forums have been (relatively) quiet. Not a lot of themes or plugins blowing things up. And it seems the upgrades are going well. Was your upgrade smooth sailing? What do you like about the new version? I need to re-jigger my child theme. I have my header images set to a specific size, I’d like to modify it to take advantage of the new flexible header option personally.
