 ## NEW FEATURES & IMPROVEMENTS
 
-* Upgraded to plotly.js v1.33.1. A _huge_ amount of features and improvements have been made since v1.29.2 (i.e., the version included in the last CRAN release of the R package - v4.7.1). Highlights include a complete re-write of `scattergl` to make it nearly feature complete with `scatter`, localization of text rendering (i.e., international translations), and two new trace types (`violin` & `table`). Read more about the v1.32.0 release [here](https://codeburst.io/notes-from-the-latest-plotly-js-release-b035a5b43e21) and the complete list of changes [here](https://github.com/plotly/plotly.js/releases).

 * The selection mode can now switch from 'transient' to 'persistent' by holding the 'shift' key. It's still possible to _force_ persistent selection by setting `persistent = TRUE` in `highlight()`, but `persistent = FALSE` (the default) is now recommended since it allows one to switch between [persistent/transient selection](https://plotly-book.cpsievert.me/linking-views-without-shiny.html#transient-versus-persistent-selection) in the browser, rather than at the command line.
 * Instead of an error, `ggplotly(NULL, "message")` and `plotly_build(NULL, "message")` now returns `htmltools::div("message")`, making it easier to relay messages in shiny when data isn't yet ready to plot (see #1116)
