Until now, we've released StreamInsight through the Microsoft Download Center, and also released it out through Microsoft Update. Going forward, we will only release new StreamInsight versions through the Microsoft Download Center and only use MU to release service packs and security fixes (should any be needed). As a result of this decision, we are pulling off the recent StreamInsight 2.1 release from MU; this release is still available in Download Center.
Don’t worry: there’s nothing wrong with the versions we’ve shipped in MU, we’ve just adjusted how we use MU. There is no action necessary from our customers as a result of this change, and we are not rolling back any changes to your current installation, so if you have installed StreamInsight 2.1 recently through the Microsoft Update, they will still work fine.
