The only issue I saw is that when we install over 3.3.0 or 3.4.0, we leave behind the older version's unpacked files on the desktop, the files from the earlier install. Those files could be deleted to save disk space. But this is not a regression and is not a critical issue.-Rob
It's not a common software behavior to delete old installation files and we shouldn't do that too.
