Some of y'all showed interest in having a bit more updates about the development as well as other stuff, so rather than having that one really outdated roadmap (which is still accurate in regards to features, just not time-wise), I want to try having this section of announcements to just give updates in regards to development and other stuff in regards to the sim.
0.2.2 is currently in the works and is about halfway done, I'm currently in the middle of finals for school so it probably wont be released until I'm done with those in a week or so, but 0.2.2 will fix many of the bugs in 0.2.1 (including the 502 bug hopefully), as well as add some new features including the ability to replace aircraft, buy from leasors/extend leases. It also sets out a number of important UI updates that wont really have an impact this time around (except for the airline selection and maybe flight research pages which are going to be the first pages to be updated), but will be important come 0.3 which will be released sometime late December/early January and feature primarily usability features and UI improvements that should make the sim a lot more stable.
As per the poll, World B will be set in 1950. While everything is ready on development end for a second world, the biggest issue currently is that there is only about 2 planes in game that would be available then. @KJS607 is working on bringing more early era planes into the sim but obviously research takes time, if you want to help feel free to drop suggestions in the New Aircraft Topic. Just be sure to cite your sources so that its easy for Kai to verify and I'm sure he'd appreciate the help. World B will start as soon as there are enough aircraft in the sim to give some variety.
