Does Microsoft Technet security bulletin MS11-069 affect Silverlight? I noticed bulletin MS11-069 replaces every other security update from bulletin MS11-039 except the update for Silverlight. Bulletin MS11-039 KB2512827 resulted in the release of Silverlight version 4.0.60531.0. This is still the version available from http://www.microsoft.com/getsilverlight/ even though it is not listed on the release history page at http://go.microsoft.com/fwlink/?LinkID=92598
