All interactivity authoring using InDesign works the same way, but no support for panorama. The panel was renamed to "Overlays" too.
The notable departure in the workflow is that you do not use the Folio panel for DPS 2015 (and InDesign 2015 doesn't have this panel)-- you export article files for use in the DPS Portal.
The Portal is where you construct your collections and article metadata, and load assets including the exported article files.
The trial runs for 30 days, available at:Digital Publishing Solution | Trial Program
There are videos and a Quick Start Guide showing the basics of the workflow at Digital Publishing Solution | Trial Resources
Note: take a look at previous posts about how to teach DPS 2015 in this forum. There are some important things to note. Critically, the new workflow can be tested for 30 days, but there is no access through a free Adobe ID similar to how the original DPS could be used without subscribing to DPS -- and this is typically an enterprise-grade price.
