## New Features
| Description |
| -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **DeviceHub**:
- Support is now provided for the following drivers:
- BACnet BacnetIP
- Danfoss FC/TSC
- OpenDNP3
- Emerson DNP3 Ethernet
- Emerson ROC800 Ethernet
- IEC IEC60870-5-102 Ethernet (Gen1)
- ODVA CIP Explicit (Gen1)
- OPCUA Client Advanced
- Profinet Acyclic |
| **Tokens**:
- You can now set up a NATS Proxy connection, which allows data to be transferred between multiple Belden Horizon Data Operations instances. You can also set up a connection between a Belden Horizon Data Operations instance and an external developer application. |
| **System**:
- Role-based access control (RBAC) now allows you to customize roles, groups, and users for user management. You can customize individual modify/view permissions in Belden Horizon Data Operations to roles and groups, which will then be assigned to respective users. |
## Enhancements and Improvements
| Description |
| -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **DeviceHub**:
- When you add a tag to a device, you now have the option of adding meta data to the individual tag. Meta data summarizes basic information about data. This feature allows you to define key-value pair data for the device output payload later on. It can then be used to find, use, and reuse particular instances of data.
- When you add a tag to a device, you can now enable the option to **Only Publish on Change of Value**. This option customizes NATS messages to be published only when the *value *parameter changes from a previous value to a new one. This only applies to numerical/string data values such as int, real, and float. It does not apply to JSON or arrays. Poll-once topics will not be affected by **Change of Value** settings. These topics will still only see a single message.
- The **Tag Formula** parameter is now available for Gen 2 driver tags. Two variables are permitted: `value` (current tag value) and `timestamp` (current tag UNIX time in milliseconds). The following math functions are available:
- sin
- cos
- sqrt
- tan
- power
- log
- exp |
| **Applications**:
- The following enhancements/improvements have been made in Belden Horizon Data Manager to the Marketplace feature:
- Ability to copy/paste and edit original compose files. You can also convert compose files into advanced config after publishing.
- Ability to specify the network mode (none, host, bridge) for a specific Marketplace component and launch it.
- Ability to create components using an advanced workflow. You can set separate hosts, networks, and container configurations. |
| **Integration**
- The MQTT connector now has an option for **Persistent storage**.
- The MQTT connector now has option to define the **QoS **parameter at the topic level. |
## Resolved Issues
| Description |
| ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **DeviceHub:**
- The Mitsubishi QJ71E71 driver no longer shows `CONNECTED` when an incorrect Station ID parameter is entered. The status will now correctly show `DISCONNECTED` if the Station ID parameter is incorrect.
- The **M **register in tags now displays all supported data types.
- The Generator driver now displays messages for Poll-Once topics in tags if a special character is used in the tag name. |
| **Flows Manager**:
- Fixed issue with flows not opening in a new window when you remotely access Belden Horizon Data Operations from Belden Horizon Data Manager. |
| **Integration**:
- Several issues and improvements have been made to the MQTT connector. |
| **System**:
- System events now correctly tag the driver name and device name. |

## Known Issues
| Description |
| ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Applications**:
- You may not be able to connect or disconnect a container to the default **host **and **none **networks in the Applications module.
- A registry can be removed without asking the user for an explicit confirmation.
- Docker doesn't restore the WG lemwg0 interface after a container is restarted. |
| **DeviceHub**:
- When you toggle a network to **ON **in Device Discovery, the WiFi icon may not display.
- When you add a tag to the Siemens S7 driver, you aren't allowed to configure a DB number greater than 255. The maximum number should be 65,535. |
| **System**:
- When the following tasks fail, error messages don't provide enough information to troubleshoot the issues.
- Template deployments
- Remote access
- Apply Marketplace templates
- InfluxDB initialization for large databases is unstable (slow, with high CPU consumption).
- Software upgrade is not supported on VirtualBox 6.1.x; upgrade attempt may result in a corrupted, unrecoverable appliance.
- 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 template. |
| **Datahub**:
- The UI incorrectly reflects the time series database size. |
| **Flows**:
- Some of the drop-down lists are not filled with the correct values until after the first deployment. |
| **Web UI**
- The UI layout gets misaligned with certain combinations of screen sizes and resolutions |
