Improved performance for documentation sites with large images

We've optimized image handling to significantly improve performance for documentation sites with large image libraries. Images are now automatically optimized and lazy-loaded, reducing initial page load time and improving Core Web Vitals scores.

Enhanced search indexing

Search indexing is now more intelligent and faster. We've improved how content is indexed to provide better search results and reduced indexing time by up to 40%.

New table component features

The table component now supports:

  • Sortable columns
  • Sticky headers
  • Improved mobile responsiveness
  • Better accessibility with proper ARIA labels

Bug fixes and improvements

  • Fixed an issue where code block line numbers were misaligned in certain browsers
  • Improved the reliability of the Fern Writer integration
  • Enhanced error messages for failed API documentation imports
  • Fixed styling issues with nested accordion components
