Read the documented changes for 4.11 at: http://www.mtu.com/upgrades/hoster.htm#411.
There is a MAJOR new feature in that the Tools > Edit Songs dialog, Select Multiple now allows changing Brand, Title and Artist on multiple songs at the same time.
NNo more RAM is required than 4.10. As Dale pointed out, 4.11 is a "FIX" release plus the Edit Songs upgrade.
