Resolved Issues

Description
DeviceHub: Fixed the following issues with the OPC UA Advanced driver: Registers that were added from browsing not being in service. Poll-once not working properly in Subscription mode. Cannot browse Ignition server tags Fixed issue with the DNP3 Ethernet driver not reading tag values with the float(32) data type. Stats data is now included for Devices in JSON Template files. Fixed issue with Metadata incorrectly displaying after unchecking the Metadata option in a Device configuration. When you edit a Device and uncheck Metadata, the data is now reset. Fixed the following issues after upgrading: Devices and Tags not working. Data from tsdata not being stored. When you add a tag to the Siemens S7 driver, you can now configure a DB number greater than 255, up to a maximum of 65,535.

System: Fixed issue with Device Certificates not resetting properly. Fixed issue with users not being able to download the DeviceHub Agent file and open source files.

Known Issues

Description
DeviceHub: If you use the Browse Tags function and try to add a duplicate tag, an error will be generated. Duplicate tags should be skipped when adding tags through Browse tags. If a read-only tag is created for the Modbus TCP driver and a Flow is created to write data to that tag, the "WriteRegisters" API may be called. The "WriteRegisters" API shouldn't be called to read-only tags. Tags can't be added to the OPC UA DeviceHub Agent driver. If you add a mount point in Litmus Edge and then add a device with the Euromap63 driver, "success=false" messages may be generated. The AB CompactLogix Ethernet Free Tag driver can't poll data up to 10 ms. When you toggle a network to ON in Device Discovery, the WiFi icon may not display.
System: Litmus Edge doesn't notify users if an activation request is rejected by Litmus Edge Manager. You are able to delete roles in System > Users if it has associated groups. Users can delete the System API key, which should be read-only. When using VirtualBox, a "Login incorrect" message may display on the Terminal User Interface during startup. If an activation with Litmus Edge Manager using a certificate signed by an unknown authority fails, attempting another activation will automatically fail. The Backup/Restore feature may create a 3-byte file, which causes an error and disables auto-backup. Software upgrade is not supported on VirtualBox 6.1.x; upgrade attempt may result in a corrupted, unrecoverable appliance. Litmus Edge docker images don't currently come with a trial license, so CA certificates can't be uploaded. Workaround: You can install CA Certificates through Litmus Edge Manager, and Litmus Edge will pick them up. If the device name is the same as the one that appears in the template, the template upload fails for the devices with the same configuration. Workaround: Edit the device name in the template file, so that it doesn't match the one in the system.
