  -:: Version:       1.0.6 ! Fix bug with missing username in %USERPROFILES% statement. Thanks to /u/TyanColte
  +:: Version:       1.0.7 / Replace "SCRIPT" WITH "TRON" in REPO_SCRIPT_VERSION, REPO_SCRIPT_DATE, SCRIPT_VERSION, and SCRIPT_DATE variables (to support Tron v10.0.0)
  +::                      * Update version comparison code to handle new v10 version string (batch can only do arithmatic comparison, not decimal)
  +::                1.0.6 ! Fix bug with missing username in %USERPROFILES% statement. Thanks to /u/TyanColte
   ::                1.0.5 ! Fix edge case where self-destruct code would be incorrectly triggered by re-using Tron's global SELF_DESTRUCT variable
   ::                        check_update.bat now uses its own internal "NUKE_OLD_VERSION" variable to check if we need to cleanup after an update. Thanks /u/wogmail
   ::                1.0.4 + Add missing :self_destruct code and fix sha256sums.txt character encoding. Thanks to /u/botopz
