# Polypane 20: Browser features and performance

**[Polypane](https://daily.dev/sources/polypane)** · 11 min read · 0 upvotes · 0 comments

## Summary

Polypane 20 is released with improvements to the Elements and Outline panels, accessibility tooling, and general browser performance. Key additions include @starting-style CSS support in the Elements panel, new accessibility checks for missing accessible names and repetition in accessible names, WCAG 2.5.3 visible vs. accessible name comparison in the Outline panel, and a cap on automatic link testing at 100 links. Performance is improved via out-of-process accessibility tree retrieval and faster CSS indexing. The release also bundles Chromium 126, which adds cross-document view transitions, plus various screenshot editor improvements and bug fixes.
