There’s a new game update out today that adds half walls and the ability to lock doors. There are also changes to the way Worlds are displayed and managed in the user interface.
The full list of changes are described in the below release video.
Door locking is particularly useful for those running retail businesses with the Get To Work expansion, as it allows the player to restrict access to certain room from non-employees.
The update will be downloaded automatically the next time you run Origin.
