| **DeviceHub:**<br />- Resolved an issue where the deviceName value was incorrectly masking special characters to `_` (underscore) from the payloads published on `devicehub.plcstatus.>` and `system.events` topics.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  |
| **Integration**:<br />- Fixed issue where InfluxDB connector with empty remote topic for outbound subscriptions would publish to `measurement = deviceName.deviceID.tagName`. Now the connector will correctly publish to `measurement = deviceName.deviceID`.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        |
| **System:**<br />- Fixed issue where Docker bridge network interfaces displayed in **System** > **Network** > **Interfaces List** after upgrading from 3.16.11.<br />- Fixed issue where deploying or upgrading Belden Horizon Data Operations Marketplace applications from Belden Horizon Data Manager failed when an **External** typed Docker network already existed.<br />- Fixed issue where events were not displayed in **System** > **Events** when backups failed to apply to one or more components.<br />- Fixed issue where permissions changed for sub-directories of `/ftp-data` after upgrading Belden Horizon Data Operations instances which prevented containers from launching.<br />- Fixed issue where upgrading from Belden Horizon Data Operations 3.16.11 to 4.0.x silently changed the active DNS resolver.<br />- Fixed issue where NATS proxy setting was disabled after upgrading from 3.16.x to 4.0.x. |
| **API:**<br />- Fixed the error response payload returned by the POST /access/accounts Access REST endpoint.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          |
