## Summary

Polypane 6.2 ships several new features for web developers: local HTML validation in the Source panel, robots.txt support in the Meta panel, one-click RTL emulation for testing bidirectional layouts, a Toybox Systems bug-reporting integration, and a new Message Bus API for cross-pane communication. The release also brings expanded accessibility warnings in the Outline panel (landmarks, links, focus order, alt text), improved color contrast checking, social media preview dark/light mode toggles, new Android and UHD device presets, rewritten update logic, and numerous performance and bug fixes.
