When there is a new version released, there will be a pop-up on your game client when you start the game.
Click the button 'Visit Download Page' to down load the new version.
You can also click 'Skip For Now' to continue playing with the current version. But sometimes we need to release a versrion that requires a mandatory update in order to ensure the gameplay or solve critical defects.
