Polypane 14.1 introduces container query support in the Elements panel with a custom-built parser (no native client-side API exists), showing container badges, names, types, and sizes in the tree view and style overview. Color pickers now display contrast lines for WCAG AA, AAA, and APCA thresholds, making it easier to pick accessible colors. New features include forced pseudo-state (hover, focus, active) on elements, a cascade layer tree overview, resolved CSS selector display on hover, and a distance-between-guides tool. The hover sync engine was rewritten for better reliability and performance. Notable bug fixes address scroll events not being captured by panes, form submission deduplication across panes, and URL search param normalization issues.
