In a comment on this post in the Field Test - 2016.2 community Bill McCormick suggested using Atelier's "Check for Updates" option from the Help menu. Here's what I get:
Atelier is InterSystems’ Eclipse-based development environment. It enables you to rapidly build solutions that leverage the performance, scalability, connectivity, and reliability of InterSystems’ comprehensive data platform.
Watch "Getting Started with Atelier" videos.
Attention! Please put an Atelier version and/or InterSystems Data Platform server version in your Atelier question.
