Shiny 1.0.1

This is a companion discussion topic for the original entry at

Shiny 1.0.1 is now available on CRAN! This release primarily includes bug fixes and minor new features.
The most notable additions in this version of Shiny are the introduction of the reactiveVal() function (like reactiveValues(), but it only stores a single value), and that the choices of radioButtons() and checkboxGroupInput() can now contain HTML content instead of just plain text. We’ve also added compatibility for the development version of ggplot2.
