 BUG FIXES and IMPROVEMENTS
+* Integrated data from `leaflet.providers` package; this breaks `data("providers")` and `data("providers.details")`. See [leaflet.providers](https://leslie-huang.github.io/leaflet.providers/). (#636)
+* Removed handling of http/https protocols for RStudio v1.1. Please update to RStudio>=v1.2 if you have missing tiles. Fixes #527. (#636)
 * Fixed [rstudio/crosstalk#58](https://github.com/rstudio/crosstalk/issues/58), which caused Leaflet maps that used Crosstalk shared data in Shiny apps, to be redrawn at incorrect times.
 * invokeRemote() now resolves html dependencies before passing them to shiny::createWebDependency() (#620).
 * Upgrade leaflet-provider to 1.4.0, enable more map variants such as CartoDB.Voyager (#567)
