Release Notes for Cumulocity 8.8


New functionalities & improvements

The numbers after the hash (#) refer to Zendesk numbers.

UI improvements:

  • The user interface has been adopted to the new Cumulocity style guide. Therefore, the user interfaces are redesigned in a lot of places. The most important changes are listed below:

Administration UI improvements:

  • Audit logs view has been improved.


  • Subtenants view has been improved.


  • Alarm mapping view has been improved.


  • Retention rules view has been improved.


Device Management UI improvements:

  • Identity tab view has been improved.


Administration improvements:

Audit logs have been improved. Alarm and operation audit logs now contain additional information.     

  • Alarms: Device name and alarm text have been added to the audit log.


  • Operations: Device name, operation description and status have been added to the audit log.


Audit logs “Filter” improvements:

  • Audit logs can now be filtered by inventory roles. The user viewing the audit log should have either global “Audit_READ” role or inventory role containing “Audit_READ” permissions for the device that the audit log is about.


  • You can now filter audit logs only by users. Note that, these users should be visible by you in order to filter them.


Device Management improvements:

Instead of being in a separate application, “Cloud Fieldbus” is now included inside the device management app. There is no need to switch applications anymore. Please note that:

  • In order to see the device database and “Modbus/CAN/OPC” tabs related to “Cloud Fieldbus”, you have to be subscribed to the “Fieldbus” application. For more info about the “Cloud Fieldbus” application, please see here.
  • Trial tenants are by default subscribed to “Cloud Fieldbus”.

Additional improvements:

  • Network interruptions no longer lead into incomplete data.
    • If the network connection is lost and reestablished, the application will still get the latest data.

Documentation improvements:

  • “Creating sub-users” section in the “User and permissions management” guide has been updated.
  • MQTT “last will” section has been updated.
