Data model inheritance does not depend on ruleset context
Valid from Pega Version 8.6
Search and Reporting Service (SRS) in Pega Platform™ 8.6 now provides an improved method of synchronizing data model by distinct users. In applications built on earlier versions of Pega Platform, some users might encounter difficulties in indexing data. Now, the data model that the system sends to SRS does not depend on access privileges. With this enhancement, each user of your application is eligible to synchronize data.
Improved indexing of StringList and StringGroup property types
Valid from Pega Version 8.6
Search and Reporting Service in Pega Platform™ 8.5 may improperly index StringList and StringGroup property types. As a result, the data model does not include the affected properties.
Upgrade impact
After upgrading to Pega Platform version 8.6, the system requires that the classes with the StringList or StringGroup type are reindexed.
What steps are required to update the application to be compatible with this change?
On the Search Landing Page, manually reindex all the classes that include properties with the StringList or StringGroup types to ensure that all your data is present in the data model. Alternatively, if finding specific instances of classes is difficult, you can reindex all classes in your application.
For more information, see Indexing class data.
Embedded properties in DX API v2 requests are no longer removed
Valid from Pega Version 8.6
In Pega Platform version 8.5, when you use the POST and PATCH v2 DX API methods with an embedded page property included in the content element of the request, the system removes all properties in the embedded page that are included in the case but are not a part of the request. Now, the merge logic has been modified to update embedded page fields sent up in the request, and keep other fields unchanged.
This feature simplifies client code and prevents data corruption.
Naming pattern changed for file data sets
Valid from Pega Version 8.6.3
File data sets are used to import from and export data to a file repository. In case of data export, prior to version 8.6.3, the first file exported had the same file name that was provided by the user in the data set, and any subsequent file exported to the repository had a unique identifier appended to it. Starting in Pega Platform version 8.6.3, each file has a unique identifier, automatically generated based on the data flow node, thread ID, and timestamp.
Upgrade impact
If your process to consume output files expects files with a specific name, it may not be able to process the resulting files correctly.
What steps are required to update the application to be compatible with this change?
If you have configured the process before updating to Pega Platform version 8.6.3, but the exported files are no longer recognized by downstream processing logic after the upgrade, ensure that the downstream tool is configured to recognize the files by a pattern rather than the full name. For example, when referring to files exported to the repository, use the * character to indicate a pattern instead of using the full file name. For example, use Export*.csv to refer to the files.
Handlebars library update
Valid from Pega Version 8.6
Pega Platform version 8.6.4 uses the 4.7.7 version of the Handlebars template to generate client-side template files. The updated version, which is the latest available, introduces a wide variety of security fixes and new features that improve application reliability.
End of active support for Cosmos React version 8.6
Valid from Pega Version 8.6
As of the release of Pega Platform™ version 8.8 in October 2022, the early adopter Cosmos React (now Constellation) UI is no longer supported. Consequently, Pega support teams no longer accept assignments and incident reports for the 8.6 version of Cosmos React and DX SDK. Upgrade to a later version of Cosmos React or Constellation to maintain support.
