  • Add diagnostic window to Modbus Slave Hub link type

  • Fix a bug where long model name strings were logged during retraining
  • OPT will not fail if free inputs are bad.

  • Fix a bug where genetic trainer result stored with older version failed to open in the newer version
  • Added an option to OPT to check the model test error before optimizing. If the test error is greater than a threshold, the OPT will fail. For submodels, if the test error is greater than a threshold, the submodel is not used and the default model is used.
  • Add an option to override reuse weights when model test error is greater than a given threshold.
  • Saving model is done to a temporary file and then renamed to the correct filename. This is done to avoid any race condition where the optimizer can open the model before it is fully saved by the retrainer.
  • Add an option to drop old submodels if there are not enough data in the new training file (< min patterns per cluster)
  • Fix an issue where downgrading to older 16.x breaks the older 16.x version. The workaround for version 2.0.2 and older is to delete the pm.ser file under c:\griffin\runtime
  • Fix a bug where FileOut will close even if it is misconfigured
  • Copy and paste will now work on Genetic Trainer Input min/max configuration dialog.
