SAPCAR and it's version numbering

Hello,

i have downloaded today the latest version of SAPCAR for Linux. Which is SAPCAR_1115-70006178.EXE

In my software folder, i have a lot of different versions of SAPCAR from some years ago, and there i have a version from August 2020 which is
SAPCAR_1320-80000935.EXE

So, why is the actual version lower then the version some years ago? Can someone explain me the versioning logic?

Thank you.
