Developer Preview: Accelerated Checkout Buttons on storefront now support Shopify Functions, Bundles, and have improved performance

Themes

We have improved the design and function of Dynamic Checkout and Accelerated Checkout buttons on storefront pages. These updates ensure that the buttons now support features like Shopify Functions and Product Bundles, providing better performance and a smoother user experience. These changes are now live on development stores and will begin rolling out to all merchants September 15.

Please note that the Accelerated Checkout buttons now hide their HTML in a custom element with a closed shadow DOM. This means that any styling or event tracking that targets the existing HTML structure of these buttons will break.

Please review this guide and the Accelerated checkout button reference to ensure your customizations remain compatible with the latest updates.
