The vast changes to the core architecture of Drupal 8 forced changes to even the most trivial contributed modules. For a robust project like Drupal Commerce, the changes amounted to a complete re-architecture that takes full advantage not just of Drupal 8 but of object oriented PHP and Composer as well. However, rather than just make sure the base feature set of Commerce 1.x continued on in Commerce 2.x, we took the opportunity to rethink some the fundamental philosophies of the project itself.
Commerce 2.x is still under heavy development for Drupal 8, with the most recent major merges including the full Payment API (which itself represents a major leap in functionality over what was provided in 1.x). In this session, you'll get a quick overview of the major new features in Commerce 2.x by way of a short technical demo that's sure to embarrass the presenter.
