Our "changelog" system that informs and previews users about all the updates and changes to AirwaySim has been recently updated a bit. Now the previews are contained in a dedicated thread and the actual changelog of implemented updates are on their own thread. At the same time the version numbering system is dropped from the public view since already a long time now all the updates have been rolled into existing game worlds making the external versioning obsolete. Visit our forums for previews and updates.
