Parallels 3.0 Mac, build 5582

Both Versiontracker, and Parallels own <http://www.parallels.com/en/download/desktop/>, posts build 5582, but it's not clear (to me) what are the changes in build 5582 as compared with 5580. If someone at Parallels is monitoring these discussions, some clarifications would be welcome.

 

Sorry, I wish to correct and update: the posted build is 5584 (not 5582). Build 5582 is the one I am running. I have posted the question (advantages-changes of 5584 over 5582) to Parallels support web form. Let's hope...
