We do not use numbered releases. Items that appear in the release notes are what is currently available and yes, those release notes are publicly available. You may also want to take a look at the Design Tools Training course that is available through Canvas Commons. I have made a few changes to that course that I have not pushed up to Commons but it might provide some useful information for you.
Hope that helps.

It's my understanding that the August 2017 release is a full release, and not the beta version any more. Since I've revised our Canvas Advanced course: Accelerated Course Design Using Cidi Labs Design Tools, I want to confirm this version number. Also, is the Admin Guide's Release Notes (https://cidilabs.instructure.com/courses/288/pages/august-18-2017) open to all users of Design Tools?
Thank you for a much improved product that makes rapid course development that much more quick and fun!
