- Fix a bug in Native OPC where only value was set to BAD and status was still good.
- Update OPC documentation for Native OPC link type.
- Update log4j and apache commons library to latest version
- Make Native OPC as the default
- Native OPC now uses OPC Server cache to read data just like OpenSCADA. This should resolve any performance issue on the OPC server with Native OPC link type.
- Native OPC can be directly configured to use a particular login credential if needed. The “Griffin Service Manager” service “Run As” credentials doesn’t have to be modified.
- Native OPC can now be used for both COM based OPC servers (localhost) as well as DCOM based OPC servers (remote computers). For remote computers, credentials can be configured on the OPC link configuration
- Native OPC now uses JNI to make the native COM/DCOM calls, this eliminates additional processes (griffinopcread and griffinopcwrite)
- Folder permissions are set so no the background service has full access to the C:\griffin folder.
- Automatically remove spaces and other characters not allowed in Grffin DB tag when configuring a data link.
- Fixed a bug where additional “Clustering only inputs” that was deleted was causing a model from being added to a hybrid model

- Fix a bug where auto start applications were not started after a reboot sometimes because the Griffin DB Service was started after Griffin Service Manager

- 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
