⚠️ Breaking Changes & Upgrade Requirements

Clean Install Required (v1.0.6+)

  • All previous OST Visualizer installations must be fully uninstalled before installing version 1.0.6 or higher.
  • Failure to do so will result in a duplicate installation, caused by the new installer framework.

Mandatory Client Update (v1.0.7+)

  • Server and client signature formats have been updated as part of the new licensing system.
  • As a result: Client versions 1.0.7 and lower are no longer compatible
  • Older clients will fail activation and validation

This is a hard breaking change with no backward compatibility.
