  • Fixed a crash that would happen when attempting to clear selection on ARIA listboxes
  • Made printing to PDF produce internal links when the HTML has internal links
  • Changed Safari’s HTTP authentication UI to not block switching tabs, navigating to other websites, or closing tabs
  • Updated Web Inspector
  • Updated CSS
  • Updated Indexed Database 2.0
  • Updated Web APIs
Safari Technology Preview 18, which is compatible with macOS Sierra 10.12, is now available to download through the Safari Dev Center for registered developers.
