This is a beta release which cleans up most of the obvious issues found and reported in alpha1. If you have existing registration type configurations, upgrading from the alpha to the beta may break the registration_commerce settings on those registration types.
This is the initial release. The basic function of this module is to generate a commerce line item attached to a Registration Entity, and trigger an update to the Registration entity when that line item is part of a completed commerce transaction. To achieve this, we attach a settings blob to each Registration Type to control whether and when to allow line item creation. We also add a Registration line item type. At this point, the line items generated are based mostly on code copied out of Commerce, and could use some cleaning up.
