### Bug fixes
* Fixed ([#1511](https://github.com/rstudio/shiny/issues/1511)): `fileInput`s did not trigger the `shiny:inputchanged` event on the client. ([#1541](https://github.com/rstudio/shiny/pull/1541))
### Library updates
* Closed ([#1500](https://github.com/rstudio/shiny/issues/1500)): Updated ion.rangeSlider to 2.1.6. ([#1540](https://github.com/rstudio/shiny/pull/1540))
