API

• The newly released custom order level fees are now available for use across both checkout and orders. You can apply and manage the order level fee via the v3 Management API for checkouts and via the v2 Management API for orders. Additionally, you can fetch any applied fees through the Storefront Checkout API.

Enhancements

• Added new Stencil CLI options to bundle and push to allow for source map inclusion in theme builds and a new section on theme optimization and source maps. Tools that provide automatic error reporting, session playback, and optimization suggestions can rely on source maps for more readable insight.

• Added Get an order metafield and Get metafields for a customer examples to the GraphQL Storefront API: orders(beta) document.

• Added additional attributes that trigger a product update webhook.

• Added a note to the Add to Cart URLs article to clarify that you need a product ID or SKU in the URL to add a coupon code.

Bug Fixes

• Corrected the discount_rules array of the v2 Customer Groups endpoint.

• Updated the maximum characters for an email from 255 to 250 when creating a custom account.

• Corrected the option_values array in the Product Modifiers endpoints.
