This is ready now.
However, I'm going to take a couple of days to collate the changes and create some documentation that describes everything clearly, with images. This way, the reference info will be ready before the update is published, not after-the-fact, if it makes it to the website at all. Just keepin' it real.

Look for this early next week in the Software Center
What Changed?
There were a few different areas that received enhancements, repairs & new features in SP13. However, I'd say the focus this round was on the Profile Generator. I'll describe some highlights of each change in the respective forum categories. They'll be brief, since there will be a page coming soon that will provide vivid details.
