Hi,
Currently, Denodo cloud free trial only includes version Denodo Platform 7.0. Denodo 8.0 is not yet included but it will be available soon.
In the meantime, you could try [DENODO EXPRESS 8.0](https://community.denodo.com/express/download) to explore the features of Denodo 8.0. You can download the express installer and get the license from the community site.
Hope this helps!
