Online Store 2.0

Online Store 2.0 is a set of features and feature improvements that make themes and theme apps easier to build, more flexible, and easier to maintain.

Many Online Store 2.0 features rely on JSON templates. You can migrate a theme's templates to add support for these features by converting a Liquid template into a JSON template, and moving any required Liquid code or HTML into sections that you can include in the new JSON template.

Upgrading to Online Store 2.0 isn't mandatory. Merchants can continue using a vintage theme if it meets their needs.
