v2.21.0 April 21st, 2021

Bug fixes for adding to carts to prevent duplication and improved dl_select_item performance. Enhancements to the data layer to improve Facebook user matching, additional content in the data layer, automatic cache clearing, new variables, and adjustments for customizations.

Data Layer Changes

Bugs

• Adds remove from cart handlers that are tied to elements to prevent duplicate remove from cart events from firing
• Adds faux url for anchors that have absolute paths. This will help improve some stores that were not always capturing the dl_select_item event in the data layer.

Enhancements

• Pushes cart contents to data layer after cart changes
  • This helps nonplus stores that are utilizing Facebook pixel in GTM to send initiate checkout events on a proceed to checkout click action and send all product data from the cart.
• Additional user parameter data has been added when user is logged in. This is to improve user matching event quality for Facebook CAPI.
• Automated CDN cache clear. This will resolve issues after upgrading your data layer but not immediately seeing the changes.
• Store campaign parameters on cart and order (see more details here)
  • Additional setting for disabling the Order Notes storage in event configuration (see more details here)
• Handle Shopify not being defined in certain pages in checkout (plus only).
• Handles themes with highly customized opening body tags. If the opening body can't be found, the script will be inserted before the closing body tag.
• Add compare to price variable to add to cart and product view events.
