All Shopify theme developers regularly release new versions with substantial enhancements for platform compatibility, search engine optimization, etc., and versions released over three years ago require an update to qualify for support.
Generally, we aim to support theme versions released within the last three years, but this timespan may be shorter to account for major upgrades (such as Product Media compatibility added in early 2020).

Why are earlier versions unsupported?
Platform changes
Shopify is always developing and expanding, so theme releases often include changes to maintain compatibility between the theme and platform. Theme support services require merchants to be using a minimum version to provide lasting and effective support solutions.
Obsolete code
A theme’s features depend on a variety of code structures which often change over time. Each theme release includes developer maintenance to reduce redundant code and potential errors from outdated code. Theme support services require merchants to be using a minimum version to reduce the number of potential issue sources.
