+- Users blocking now relies on UUID rather than ID. A blocked user that leaves a room and comes back will stay blocked.
+- The text chat was redesigned to be prettier and to use more features :
+  - The chat is now persistent bewteen discussions and always accesible
+  - The chat now tracks incoming and outcoming users in your conversation
+  - The chat allows your to see the visit card of users
+  - You can close the chat window with the escape key
+- Added a 'Enable notifications' button in the menu.
+- The exchange format between Pusher and Admin servers has changed. If you have your own implementation of an admin server, these endpoints signatures have changed:
+  - `/api/map`: now accepts a complete room URL instead of organization/world/room slugs
+  - `/api/ban`: new endpoint to report users
+  - as a side effect, the "routing" is now completely stored on the admin side, so by implementing your own admin server, you can develop completely custom routing
