Developer preview release notes: September 2, 2026

Variant links: Links that name a variant, like the ones Shopify submits to a Google Shopping feed, now open on that variant instead of the product's default.

Cart refresh: Reload the cart after your own code changes it, like a cart created on your server.
Local HTTPS certificates: Hydrogen creates the certificates for Customer Account testing, so local login setup takes one command or none.

Cart session attribution: Carts and Customer Account sessions stay in step, so signed-in shoppers reach checkout with their saved details instead of a guest flow.

Cart attributes: Attach order-wide data like gift messages to the cart, and per-line data like engraving text to the lines it belongs to.

Standard page view events: Hydrogen storefronts used to report only the first page load, leaving client-side navigations invisible to analytics and performance tooling. Every navigation now emits a page view, matching how liquid themes report events.

Shop Pay button without shop-js: The button used to render blank until Shopify's hosted script loaded. Hydrogen now renders it directly, so it shows up styled and clickable right away, before any JavaScript runs.

Local HTTPS for Customer Account development: Test login flows on a trusted local hostname, without a tunnel or hand-rolled certificates.

Pluggable logging: Set how much Hydrogen logs and forward warnings and errors to your own observability tooling.
