This update is mainly focused on the multiplayer menu. After some comments saying that the menu from Version 4.8 was not detailed enough, version 4.9 makes them more detailed. Now, if you press on the multiplayer feature in the main menu you'll go to a small "how to play" menu about the multiplayer feature. Then, you'll go to the multiplayer track list which shows a small preview of the racing track you will choose.
This version has the "Sonic" character changed with the "Shy Guy" character. However, the "Shy Guy" character doesn't look that great and still has some bugs. We might see this fixed in the next version. Apart from this and the multiplayer menu not much has been added. For more info see the changelog:
