What changed in this version (10.6.0)... when I enter the MyEclipse Configuration Center I see this update but there is no full offline download or information on what this update contains. Could you tell me what is actually in this version and if it was a legit update?

There is a Help topic describing the update: MyEclipse Learning Center -> Notes -> Release Notes -> MyEclipse 10.6

10.6 is a legit update, the installers, new and noteworthy and release notes will be uploaded to the portals later today - we typically just release to the update sites over the weekend.

Please see this link for the release announcement: http://www.myeclipseide.org/PNphpBB2-viewtopic-t-29228.html
