+===========
 
 This is a significant release for Shiny, with a major new feature that was nearly a year in the making: support for asynchronous operations! Until now, R's single-threaded nature meant that performing long-running calculations or tasks from Shiny would bring your app to a halt for other users of that process. This release of Shiny deeply integrates the [promises](https://rstudio.github.io/promises/) package to allow you to execute some tasks asynchronously, including as part of reactive expressions and outputs. See the [promises](https://rstudio.github.io/promises/) documentation to learn more.
