The submission title is misleading.

> NOTE: This is a DRAFT of the Go 1.6 release notes, prepared for the Go 1.6 beta. Go 1.6 has NOT yet been released. By our regular schedule, it is expected some time in February 2016.

Unless the title has been updated since your comment, it is accurate. The beta is out today, builds available from https://golang.org/dl/#unstable

1.6 has not been released, but this is the 1.6 Beta 1. It should be considered unstable, obviously.
