 * Closed #89: Exported `as_widget()`, which helps to coerce objects into ipywidgets, and is especially helpful for creating ipywidget objects before passing to `register_widget()` (this way, the ipywidget can then be updated in-place and/or used as a reactive value (`reactive_read()`)). (#90)
 * Closed #94: New `SHINYWIDGETS_CDN` and `SHINYWIDGETS_CDN_ONLY` environment variables were added to more easily specify the CDN provider. Also, the default provider has changed from <unpkg.com> to <cdn.jsdelivr.net/npm> (#95)
 * A warning is no longer issued (by default) when the path to a local widget extension is not found. This is because, if an internet connection is available, the widget assests are still loaded via CDN. To restore the previous behavior, set the `SHINYWIDGETS_EXTENSION_WARNING` environment variable to `"true"`. (#95)
+* Closed #86: Fixed an issue with `{ipyleaflet}` sometimes becoming unresponsive due to too many mouse move event messages being sent to the server. (#98)
