Highlights

• Added an example to our Collapse plugin docs to show how to use horizontal collapsing. This has long been possible via our JS, but we never had an official class to utilize it.
• We've replaced the deprecated color-adjust with print-color-adjust in our Sass files as part of the Autoprefixer v10.4.6 issues. This should quiet the issues folks have seen from that dependency change. If you're using our distribution CSS files, like bootstrap.min.css, you may still see the warning.
• Tweaked the size of small and .small to compute to a whole pixel value (was 12.8px and now is 14px).
• Improved accessibility around our dropdowns, color contrast, and role attributes.
• Fixed some broken links to supporting documentation.
• Updated dependencies across the board.
