Some of the most interesting new modules I saw posted to drupal.org in September:
(for Drupal 8) Allows you to specify the routing configuration YAML for a Views page. Meaning, you can use custom access control callbacks, default parameters, etc. Sweet!
Provides replacement interfaces for the parts of Drupal Commerce that are table dependent and non-mobile responsive by default. These include Responsive Cart, Responsive Checkout, and Responsive User Facing Orders.
