You may have noticed that last week, as usual, we cut a new branch — swift-3.0-branch — from master when we did the CI update and pushback of source changes. Due to an oversight, I missed mentioning the branch info in my email. (my apologies!)
This will be our final preview and release branch for the Swift 3 release, and is being used to converge the Swift 3 release from now until it is declared ‘GM'. Any changes that are required for Swift 3 should be nominated for inclusion via pull request against the swift-3.0-branch branch.
