# Framework v2.0.0

Released on 2025-09-14.

## Framework Changes

- Released the Framework 2 asset line after the RC series that rebuilt responsive screen, view, orientation, and bit-depth behavior.
- Added the v2 selector and screen mixin stack, including screen size, orientation, bit-depth, and selector-helper utilities used by generated CSS.
- Expanded responsive utilities across Flex, Grid, Size, Scale, Aspect Ratio, Pixel Ratio, Background, Text, Visibility, and related component selectors.
- Reworked the plugin render runtime with the v2 Overflow Engine, Clamp Engine, image-settling behavior, content limiter fixes, and generic height-budget handling.
- Added `.screen--1x` preview support and corrected UI scale-factor handling so plugin previews render at predictable browser scale.
- Polished v2 Label, View, Flex wrapping, layout stretching, table, progress, rich text, and title bar behavior before the stable asset publication.
- Published the stable `/css/2.0.0/plugins.css` and `/js/2.0.0/plugins.js` assets after the final plugin-polish pass.

## Upgrade Notes

- Review the Framework v2 upgrade guide before moving markup from the 1.x release line.
- Test responsive variants across screen size, orientation, and bit-depth; v2 changes how the screen and view layers coordinate those selectors.
- Recheck custom overflow and clamp markup because v2 moved that behavior into a broader Overflow Engine and Clamp Engine runtime.
- The old `framework_v2` feature flag was removed immediately after the release window; v2 behavior became the default Framework path.

## Documentation Changes

- Added v2 overview, enhancement, troubleshooting, and upgrade guide pages.
- Rebuilt responsive, flex, grid, overflow, clamp, scale, screen, label, progress, and table-overflow docs around the v2 behavior model.
- Added responsive test documentation and examples for validating device, orientation, and bit-depth combinations.
- Updated Framework navigation and sidebar structure so v2 guides and component pages were discoverable from the production docs.
