As of Dec 5th 2017, inventory_quantity and inventory_policy fields accessed through a json Liquid filter are deprecated. The json filter will not output those fields for shops created after Dec 5th. If you want to consume inventory information about a product, you can leverage variant.inventory_quantity and variant.inventory_policy. We recommend using that information behind a setting that the merchant has to turn on. This is a part of our efforts which kickstarted last year to eliminate bots and crawlers from knowing inventory levels of products from stores that they haven't explicitly been granted access to. Themes in the Shopify Theme Store will be updated before Dec 5th, 2017.

What is recommended as the alternative? Even if just to display in stock/out of stock/backorder?
What is alternative to read the field variant.inventory_quantity?
