Shiny 1.6

This is a companion discussion topic for the original entry at

We are thrilled to announce that Shiny 1.6.0 is now on CRAN! Install it now with:
install.packages("shiny") A lot of hard work went to this release to vastly improve four main areas: theming, caching, accessibility, and developer experience.
Improved theming (and Bootstrap 4) support This version of Shiny makes it much easier to customize the appearance of your applications. Shiny now integrates with the {bslib} package, which provides Bootstrap 4 and Bootswatch themes, and also makes it much easier to modify colors, fonts, and more.
