Verified facts
What happened
The Polaris 2.0 release candidate is available for embedded App Home interfaces and introduces the new Shopify admin visual styles.
Shopify says its new admin design began rolling out progressively to merchants on September 15, 2026.
Inside the Shopify admin, Polaris 2.0 components match the design available in that store. Stores still using the previous design retain the earlier visual style.
Adoption is explicit: apps using polaris-1.js or the legacy polaris.js URL do not move to Polaris 2.0 automatically.

Why it matters
This gives app teams a way to test a staged design transition without requiring every test store to have the new Shopify admin experience.
For apps in Built for Shopify, the May 1, 2027 update deadline makes compatibility work a certification concern, not only a visual refresh.
Apps rendered outside the Shopify admin default to the new visual style, so external preview and testing environments may not represent the older in-admin appearance.
