Looking for Legacy Cura LulzBot Edition v21.08

From the Lulzbot site:
“Users that need to use existing GCode files can restore compatible firmware ( or below) through Legacy Cura LulzBot Edition v21.08.”

The oldest I can find is v2.6.52. Not even the same numbering system.
Anyone know where I can find v21.08?
