Product Versions Removed From API Responses

As of July 16 2019, we will no longer be supporting product versions in our API responses. The concept of a product version has been replaced by product price points. This mainly affects the subscription response, which currently includes a product_version_number. This subscription hash is included when fetching subscriptions, and also in a lot of webhook payloads.

The subscription hash now includes a product_price_point_id, which can be used in lieu of the product version number going forward. For more information on the product price points feature, see the documentation here.
