By Purus:

In the UPGRADE.txt , "upgrading to the latest release" section also should have a note to remove the "profile" directory.

Some people might upgrade from 1.8 to 1.8.1, where the unwanted files will be present in the "Profile" folder. Also this file is also removed, so adding up the number of unwanted files.
