Liquid templates can now compose pages with blocks and partials
Shopify developer change
MerchantDiff detected this entry in Shopify's official developer changelog on July 21, 2026.
This Shopify update is categorized as API, New, Liquid.
What changed
The Liquid July ’26 developer preview introduces a simpler way to build theme pages. Page structure can live directly in a Liquid template, where developers and coding agents can read and edit everything in one place. The peview adds two Liquid tags: {% block %} renders a reusable theme block directly from a template. Name the block, pass its inputs, and provide body content much like you would with {% render %}. {% partial %} defines a named region of server-rendered HTML that JavaScript can refresh without reloading the full page.
