- 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. | | **API**:

- 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. | ## Deprecated Components and Features | Description | | -------------------------------------------------------------------------------- | | **DeviceHub**:
- The Mitsubishi QJ71E71 (Gen1) driver is no longer offered. |
