Upgrade notes for Shiny 1.7.3

Bug fixes

  • Shiny 1.7.0 changed the icon(lib="fontawesome") implementation from a bundled copy of fontawesome, to the {fontawesome} package. This led to issue #3688, where icons that were previously working, were now breaking. That’s because {fontawesome} 0.3.0 and earlier did not have support for icon names used in Font Awesome 5 and earlier, only the newest icon names used in Font Awesome 6. Now, {fontawesome} 0.4.0 has restored support for those older icon names, and Shiny has updated its {fontawesome} requirement to >=0.4.0.
