TL;DR: Yeager should re-launch into its 11th iteration today, but ongoing work on major technical upgrades and a planned critical change relevant to Yeager made me delay the launch for a while.
The slightly longer version: I have big plans for AirlineSim, as outlined by the roadmap and discussed in previous updates. To prepare for those, I have been busy taking care of a long-overdue modernisation of AirlineSim's technical foundation for several weeks now. As usual, this has taken and is taking a lot longer than originally planned as AirlineSim's technical roots in the early 2000s are showing a lot of cracks. This alone wouldn't warrant delaying Yeager. I could always launch with the current version. But firstly, having a new short-term game world for a first real-world test of the past weeks' work would be invaluable.
And secondly, I would love to get in a crucial game design tweak before Yeager goes live again. As Yeager starts with second-hand aircraft, I want to test out a set of reworked pricing formulas that Fabian has come up with. The goal of these is to counteract the often extreme initial growth of some airlines fuelled by far-to-cheap aircraft in an effectively empty market.
This means there are two projects to be finished before I am ready to flip the switch: The "spring migration" and the aforementioned formulas. As such, I can't really tell how long of a delay it's going to be. I can only ask for your patience.
Thanks a lot and have fun!
