The following changes were introduced to Cameo DataHub version 18.4 beta

• Starting from this 18.4 beta version of Cameo DataHub, it is possible to create an HP ALM data source.
• Cameo DataHub can work with HP ALM data sources just like DOORS and DOORS Next Generation data sources.

The following change was made to Cameo DataHub version 18.3 SP1

• Support for DOORS Next Generation version 6.x was added.

The following changes are from the 18.3 version of Cameo DataHub

• A new link type was incorporated and this is the DHTrace link.
• Two new DataHub operation modes were introduced. They are Copy Data and Create DHTrace, to copy data and create DHTrace links between source and target, and Create DHTrace, which only creates DHTrace links.
• New menu items were added to Check Changes, Update DHLinks and Remove DHLinks which offer more options to check for DHTrace changes, clear suspect DHTrace links, and remove DHTrace link respectively.
• A new menu item, Remove DHTrace, was added to the DHLink panel context menu.
• A new DHTrace Summary dialog was introduced, which appears on selecting Check Changes > Check Trace Changes Recursively. This dialog allows you to clear suspect DHTrace links, if you choose to do so.
• Support for DOORS client version 9.6 was added.
• DataHub Relation was renamed to DHLink.
• Server component of Cameo DataHub is no longer present separately. Previously the relation map was stored on the DataHub Server leading to conflicts in multi-user environments. Now the DHLink map is stored along with the project thus resolving conflicts involving multiple users working on the same data sets.
• Cameo DataHub no longer supports IBM^® Rational^® Requisite Pro or Cameo Requirements+ or MagicRQ. It only supports IBM^® Rational^® DOORS^®, IBM^® Rational^® DOORS^® Next Generation, and CSV data sources.
• Scope sync, auto sync and manual sync are no longer present separately. They have been combined into a single Synchronization mode, which can be either unidirectional or bidirectional, and works exactly like scope sync relation.
• OSLC link support for IBM^® Rational^® DOORS^® Next Generation has been added.
• OSLC Query support for IBM^® Rational^® DOORS^® Next Generation has also been added.
• To resolve conflicts between un-synchronized data, a new Conflict Dashboard has been added to resolve conflicts and monitor status of data nodes. The Conflict Dashboard allows you to fine tune the way synchronization takes place within projects.
• Text search from DataHub Explorer and Alias Explorer was added.
• Cameo DataHub inactive data source filtering was added.
• Data copy progress bar was enhanced with better status messages.
• The copy dialog was improved, and it allows for a variety of mapping between source and target types.
• Migration support for DataHub 17.0.2 onwards was made possible.
