Ah. Thanks. That must be where I had seen it. Unfortunately, it's not in the PDF that pops up automatically after the command center completes the upgrade. That PDF just talks about how to work around the lack of preset management, after the new samples have been imported. It overshadowed my glimpse of the other PDF.
I still feel that any upgrade should be completed without much, if any, user intervention. I realize that takes more SW development, but one relatively small SW project can save thousands of individual user frustrations. Some of us are entangled in a wide variety of sophisticated tools, and it gets very hard to remember all the app-specific details.
