We've just released a major app and server update, and added support for Dwarf Fortress 0.44.12. Subscription users will be updated to 0.44.12 over the next couple days. I hope everything goes smoothly for them and for everyone else. If you have any issues, please let me know.
The new world map/missions screen added in 0.44.12 is not available in the app yet, it will be added in one of the usual app updates soon.
