# Neue Version automatisch auf den Keymaster hochladen (msco.mbm.wtf -> /download, Launcher-Updates).
# Läuft nach dem Release-Build von selbst (MSCO.csproj bzw. MSCO.Launcher.csproj) - oder von Hand:
#   powershell -ExecutionPolicy Bypass -File release.ps1 -Product mod -File bin\Release\MSCO.dll
#
# Braucht den Release-Token des Keymasters (RELEASE_TOKEN in dessen .env), lokal als Umgebungsvariable
# MSCO_RELEASE_TOKEN oder in %AppData%\MSCO\release-token.txt. Ohne Token wird nichts hochgeladen.
# Gibt es die Version auf dem Keymaster schon, passiert nichts - also einfach die Version erhöhen und bauen.
