 ## NEW FEATURES & IMPROVEMENTS
 
-* Upgraded to plotly.js v1.35.2. 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).

 * Support for **sf** (simple feature) data structures was added to `plot_ly()`, `plot_mapbox()`, and `plot_geo()` (via the new `add_sf()` function). See [this blog post](https://blog.cpsievert.me/2018/03/30/visualizing-geo-spatial-data-with-sf-and-plotly) for an overview.
 * New "special arguments" `stroke`, `strokes`, `alpha_stroke`, `span`, and `spans` were added for easier control over the stroke (i.e., outline) appearance of various (filled) graphical marks. For an overview, see the **sf** blog post linked to in the bullet point above and the new package demos (list all demos with `demo(package = "plotly")`).
 * The selection (i.e., linked-brushing) 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.
