Unofficial changelog tracking changes to Shopify's Polaris web components CDN bundlehttps://polaris-changelog.dev/https://polaris-changelog.dev/entry/2026-03-26_5ff803d5/https://polaris-changelog.dev/entry/2026-03-26_5ff803d5/Checkbox gains labelAccessibilityVisibility property, fixes HSL color rendering bug, and improves React wrapper slot handling. - Checkbox gains a new labelAccessibilityVisibility property with default value 'visible' for controlling label visibility to assistive technologies. - Fixed a bug in HSL-to-RGB color conversion where the blue and green channels were swapped, producing incorrect color output. - Fixed a color channel range validation bug in utilities where the wrong variable was used in the 0-100 vs 0-255 check. - The React wrapper now skips slot div wrappers for string props that match native element properties on the component prototype. - The React wrapper correctly clears stale string attributes when a slot prop changes type from string to non-string. - Base element text color now falls back through an intermediate --t-text-26021 CSS custom property, enabling theme-level overrides.Thu, 26 Mar 2026 08:13:37 GMThttps://polaris-changelog.dev/entry/2026-03-17_e40d7302/https://polaris-changelog.dev/entry/2026-03-17_e40d7302/ChoiceList fixes event bubbling, Menu reduces unnecessary re-renders, and design tokens updated to version 26021. - ChoiceList now intercepts change and input events to ensure they only fire when the event originates directly from the component, preventing duplicate events from bubbling. - Menu's MutationObserver now filters out attribute mutations on the Menu element itself, avoiding unnecessary re-renders when its own attributes change. - ColorPicker removes redundant render calls after value changes and form resets. - CSS design tokens updated from version suffix 25111 to 26021, removing intermediate Polaris token variable fallbacks from typography and color properties. - The React-to-web-component event bridge now routes change, error, load, and toggle events through dedicated logic for more reliable listener synchronization.Tue, 17 Mar 2026 12:35:08 GMThttps://polaris-changelog.dev/entry/2026-03-06_913ce26d/https://polaris-changelog.dev/entry/2026-03-06_913ce26d/Initial baseline capture of Shopify Polaris web components bundle. 59 components and core infrastructure deminified from the CDN build. - 59 web components identified and extracted into individual files - Core infrastructure split into preact-core, preact-hooks, decorators, property-types, dom-bridge, base-element, and utilities - Popover API polyfill extracted separately - Component registry and React wrapper in exports.jsFri, 06 Mar 2026 00:00:00 GMT
