Verified facts
What happened
The official Shopify Developer Changelog identifies Polaris CDN 1.1 as a release candidate, not a general-availability release. The evidence is single-source: evidence:402dafaa32b1cb29ce505a00.
Polaris Web Components loaded from the Shopify CDN are moving to semantic versioning. The changelog says developers can test the 1.1 release candidate by updating the Polaris URL they load.
The release candidate adds EmptyState and Number components, plus fontSize properties for Heading, Paragraph, and Text, visibleMonths for DatePicker, and supplementalStart for Page.
The changelog lists fixes for overlays, pages, modals, popovers, menus, tooltips, DatePicker, and other controls, including a DatePicker change intended to prevent a second input and change event when the same value is set again.
