 ### Updates
 
+- Added the emote feature to Workadventure. (@Kharhamel, @Tabascoeye)
+  - The emote menu can be opened by clicking on your character. 
+  -  Clicking on one of its element will close the menu and play an emote above your character. 
+  -  This emote can be seen by other players.
 - Mobile support has been improved
     - WorkAdventure automatically sets the zoom level based on the viewport size to ensure a sensible size of the map is visible, whatever the viewport used
     - Mouse wheel support to zoom in / out
