What's new in this version:

Monitoring:
- Updated HwInfo engine to better support newer hardware

Enterprise:
- Introduced two new command-line switches : --overwrite-report-file (for test) and --overwrite-upload-result-file (for stability certificates). They will allow you to overwrite the existing report file instead of creating a new one and appending a number. Default is false to keep the current behavior.
- When running a stability certificate, the upload result file will now be written in case of success and error, containing information about the error encountered.
- If auto-close is set and the upload fails, OCCT won't auto-close and stay open to allow you to retry the upload
