Hello Swift Developers-
As outlined in Ted’s Swift 3.1 Release Process blog post, for the past month, we’ve been periodically merging master to the swift-3.1-branch branch. We will be doing one final merge of master to the swift-3.1-branch on January 17 at noon (Pacific). Note that we’ve pushed this back a day due to the MLK Jr. Day holiday. Any changes landed after that time will require approval via a pull request against the swift-3.1-branch branch in order to include them in the Swift 3.1 release. After this final merge, development on master will be targeted for Swift 4.
Snapshots of the swift-3.1-branch will be made available on the downloads page (https://swift.org/download/). Snapshots will be made available daily, if all package generation CI tests are passing.
