This is the first stable 7.x-2.x branch release. The 7.x-2.x branch is quite different from the 7.x-1.x branch -- it uses 3rd-party libraries for parsing the code, in place of the Grammar Parser project. Installing this release or updating from the 7.x-1.x branch requires Composer. See https://www.drupal.org/docs/7/modules/api-module/create-your-own-api-7x-...
for installation and upgrading instructions.
Now you can install Varbase Media with any Drupal 8 site. Even if installed with the Minimal or Standard profile.
However, using it with Varbase distro gives you way much more cool stuff!
