The original version HALCON 12.0.4 was substituted by an updated version HALCON 12.0.4.2, as the originally released version of HALCON 12.0.4 had a few issues:
- The protection format for HDevelop files has been changed to improve security.
- In rare cases, get_data_code_2d_results crashed during print quality inspection. Creating an HDevProcedure instance from a local procedure in an HDevProgram did not work when that local procedure referenced other local procedures.
