MAIN CHANGES
The addition of the UHF League is by far the star of this update, which is loosely based on UHF League - #42 by MoonKnight . This was hard to implement because there was no support for dynamically-created missions, so it required a lot of changes to underlying systems. For this reason, this is considered a dangerous update and the probability of an emergency update is quite high 
A basic explanation on how the league works is provided by the in-game help. This is a first rough approximation of this feature. Let’s see how it behaves over the coming week, and we’ll iteratively refine it based on your feedback.
Also, I’ve noticed that the feature to “Unmount all” from the Fleet loadout has crashed on a few players. I don’t know exactly what is wrong. The crash occurs after you click on “Unmount all” on the Loadout screen and possibly re-loading more equipment(?). The game won’t crash immediately, but it will crash when you try to save your changes (on the previous screen). If you can replicate the crash, please post with your experience here, it would be much appreciated.
COMPATIBILITY
You will lose:
- any in-mission progress
- all graphics options, which includes your window/borderless/fullscreen setting.
- if any options have been removed or added to a new version, then all menu options (not just graphics) will be lost.

BACKUPS
You are reminded that during Early Access you are responsible for backing up your own progress. Make a copy of everything under C:\ProgramData\InterAction studios\CIU (including all sub-folders). 
Never rename files or move them from one version folder to another. Simply make a copy and then later put it back exactly where you found it.
