+* Several new features and improvements related to accessing plotly.js events in shiny (learn more about them in this RStudio [webinar](https://www.rstudio.com/resources/webinars/accessing-and-responding-to-plotly-events-in-shiny/)):
     * The `event` argument of the `event_data()` function now supports the following events: `plotly_selecting`, `plotly_brushed`, `plotly_brushing`, `plotly_restyle`, `plotly_legendclick`, `plotly_legenddoubleclick`, `plotly_clickannotation`, `plotly_afterplot`, `plotly_doubleclick`, `plotly_deselect`, `plotly_unhover`. For examples, see `plotly_example("shiny", "event_data")`, `plotly_example("shiny", "event_data_legends")`, and  `plotly_example("shiny", "event_data_annotation")`, 
     * New `event_register()` and `event_unregister()` functions for declaring which events to transmit over the wire (i.e., from the browser to the shiny server). Events that are likely to have large overhead are not registered by default, so you'll need to register these: `plotly_selecting`, `plotly_unhover`, `plotly_restyle`, `plotly_legendclick`, and `plotly_legenddoubleclick`.
     * A new `priority` argument. By setting `priority='event'`, the `event` is treated like a true event: any reactive expression using the `event` becomes invalidated (regardless of whether the input values has changed). For an example, see `plotly_example("shiny", "event_priority")`.
