To launch a new version first open database/Versions.txt...
add the new version to the list.
E.g...
Add "2.2" into the array.
Then make sure your database is set to your clone.
E.g:
https://raw.githubusercontent.com/hedgehog125/Auto-Update-Database/master/
Next, use the JSON generator located in [AutoUpdate_v2 repo]/Update Launcher.py.
Hope this helps! :D
