 features and improvements
 
+ * New method *clearGlGroup* removes a group from leaflet and the Leaflet.Glify instances.
+ * The JavaScript methods of the `removeGl**` functions was rewritten to correctly remove an element identified by `layerId`
+ * `clearGlLayers` now correctly removes all Leaflet.Glify instances
+ * When showing/hiding Leaflet.Glify layers, they are set to active = TRUE/FALSE to make mouseevents work again. #48, #50
+
 bug fixes
 
   * src version now works also in shiny. #71
+  * added `popupOptions` and `labelOptions`. #83
+  * added `stroke` (default=TRUE) in `addGlPolygons` and `addGlPolygonsSrc` for drawing borders. #3
+  * Labels work similar to `leaflet`. `leafgl` accepts a single string, a vector of strings or a formula. #78
+  * The `...` arguments are now passed to all methods in the underlying library. This allows us to set
+    additional arguments like `fragmentShaderSource`, `sensitivity` or `sensitivityHover`.
 
 documentation etc
 
+ * Added some @details for Shiny click and mouseover events and their corresponding input. #77
+ * Use `@inheritParams leaflet::**` for identical function arguments
+
 miscellaneous
 
+ * unified / simplified the dependency functions/calls
+ * add option `leafgl_json_parser` to change JSON-parser via options. Possible values are:
+    - `jsonify` (default)
+    - `yyjsonr`
+    - Custom JSON converter like `jsonlite::toJSON` for example.
