I just submitted an update to one of my apps, and was very happy to see a feature that solves a problem I have been wanted a solution to for a while. When I updated, I was given the option of allowing Apple to automatically release the update, or requiring that I manually release it. This is great news because when I release the 2.0 version of a couple of my apps, I plan on raising the price. This helps to coordinate the timing of that immensely.
I just figured I'd share with those of you who might not have updated an app since the changes went into effect.
