 min_slic3r_version = 2.1.0-alpha0
+1.0.1 Updated MK3 firmware version check to 3.8.0, new soluble support profiles for 0.6mm nozzle diameter MMU2S printers.
 1.0.0 Updated end G-code for the MMU2 profiles to lift the extruder at the end of print. Wipe tower bridging distance was made smaller for soluble supports.
 1.0.0-beta1 Updated color for the ASA filaments to differ from the other filaments. Single extruder printers now have no extruder color assigned, obects and toolpaths will be colored with the color of the active filament.
 1.0.0-beta0 Printer model checks in start G-codes, ASA filament profiles, limits on min / max SL1 exposition times
