I have a PC and a laptop. I ran configman on 12.0.2, deleted 12, and then installed 13.0.1 - and then ran configman load on the saved file. I did this on each computer (therefore twice) and the libraries paths were not reinstalled. I see the paths when I open the saved config file in Wordpad.
I can reload my libraries manually as I have for past updates (I keep them in their own directory/folder just for this reason, along with my projects), but I am letting you know they did not reinstall as it seems they should have (twice).
