This new version introduces the Networking features: create online multiplayer games in microStudio! microStudio handles all the difficult stuff for you, that is to say you won't have to set up and run your own server. You will just code your client and server in microStudio and run them directly from the microStudio editor.
When your game is ready, you can export the game client as an HTML5 app and the game server as a NodeJS app ready to be installed on your own server.
