We will also be landing some source changes on both master and the swift-3.0-preview-3-branch. These changes include updates required for the SDK update for Swift 3, as well as reverting some changes from the swift-3.0-preview-3-branch that were backed out in the process of converging and qualifying the preview branch. (Those changes will remain on master, and will be rolled into the swift-3.0-preview-4-branch when it is cut.) We expect the upgrade process to take several hours.
