Upgrade your customized checkout
Stores with checkout.liquid enabled can now upgrade to a new version of Shopify Checkout, unlocking powerful new checkout features—like subscription apps and local pickup—while keeping their checkout.liquid customizations intact.
All checkout upgrades need to be completed by February 26, 2021. Stores that don’t complete the upgrade within the checkout upgrade window (January 25, 2021 to February 26, 2021) will be upgraded automatically, which might cause some customizations to break.
Find instructions for the checkout upgrade process in the Shopify help center.
Only stores with checkout.liquid enabled need to perform the upgrade.
