Design updates include new pane resize indicators, focused pane outlines, and sortable workspaces. Accessibility improvements include clearer WCAG version wording, aria-label role warnings, and better focus order handling for radio groups. The release also adds new CSS pseudo-class support (::checkmark, ::picker-icon, carousel-related selectors), screenshot quality fixes, and emulation improvements. Built on Chromium 136. ## Full article daily.dev links to this article rather than hosting it.
