It's been almost 2 years since an update! This is just a little one in preparation to remove the launcher script (launcher.bat or launch.sh) and newloaderv4.1.exe. It won't change anything about the game itself.
Changes in this update (build 2105182) are:
- Moved map ain files to a separate download depot.
The change is a separate solution to the "Rebuild AIN Bug" I detailed in this old update. As of this update, the scripts still run at launch. There will be another update in the coming weeks to disable them and have Steam run the executable directly.
