The store information object features array is updated. It now includes sitewidehttps_enabled, facebook_catalog_id and checkout_type.

"features": { "stencil_enabled": true, "sitewidehttps_enabled": false, "facebook_catalog_id": "", "checkout_type": "klarna" } 

This will allow developers to identify if the store has the correct settings enabled for the app or theme being installed.
