Ok when a new version of SSL becomes available and you upgrade, what are somethings that you have to do as far as your music library is concerned. Do Overviews have to be rebuilt etc. etc.?

This depends on whether the overviews have been changed in some way or not. For example in 1.4 the overviews were made brighter. You could still use the old ones though. The new ones would just overwrite the old ones as you played the tracks or built overviews.

Ok, cool I installed 1.4 and let the overviews build for my Library. Thanks my man.
