The reload button has been relocated to match Chrome's layout. The Outline panel now warns about non-descriptive link text, redundant image alt text, and shows autofocus elements. Additional improvements include updated Discord/Slack social previews, better scroll syncing when the body element is the scroll container, and performance gains in the elements panel. Patch releases 6.3.1 and 6.3.2 add custom live reload ignore patterns, custom font size in Live CSS, updated Twitter/Google previews, and various bug fixes. ## Full article daily.dev links to this article rather than hosting it.
