Published Release Notes

Automatically detect the most important themes in text

Text analyzers can now automatically recognize the most important concepts that are expressed in text and mark such concepts as entities of type auto_tags. You can use auto_tags to group similar content by its themes and reduce the dimensionality of text to the most important features.

For more information, see Text extraction analysis.

Manage propositions in multitenant environments

Proposition Management is now supported in multitenant environments of Pega® Platform. The DisablePropCache Dynamic System Setting switches off the use of a proposition cache. When you import propositions in strategies, you can import only versioned propositions (Decision Data rules). Unversioned propositions are not supported under this setting, but these can be converted to versioned propositions.

For more information, see Unversioned propositions, Synchronization of the proposition cache, and Converting groups with unversioned propositions.

Configure the window size at run time in event strategies

You can now configure an Event Strategy rule to dynamically define the window size at run time by using a property value of the incoming record. To configure the window shape for dynamic size setting, you can use any property from the inheritance path that is available to the event strategy. This enhancement provides greater flexibility for strategy designers and broadens the scope of business scenarios in which event strategies can be applied.

For more information, see Event Strategy rule form - Completing the Event Strategy tab and Dynamic window size behavior.

Aggregate data in interaction history summaries

You can now group, aggregate, and filter interaction history data in a single strategy component. By using interaction history summaries, you can create refined data sets that simplify strategy frameworks and accelerate decision-making. Aggregated data sets are easier to process, manage, and troubleshoot.

For more information, see Data Sources landing page

New shape on the strategy canvas

The Strategy rule has been enhanced with the Embedded strategy shape, which simplifies the configuration of decisioning strategies that simultaneously apply to multiple types of audiences, for example, Devices, Households, and Subscribers. The Embedded strategy shape eliminates the need to switch between various classes to create a substrategy for each audience type that you want to target. Now, you can perform all configuration tasks on a single strategy canvas.

For more information, see Strategy components – Embedded strategy and Multilevel decisioning strategies.

New interaction history attribute

Pega^® Platform 7.4 introduces the pySubjectType attribute that is used in interaction history aggregations. This attribute is populated for interaction history records that were created in release 7.4. For records that originated in earlier releases, the attribute must be set in the following scenarios:

• Single-level decisioning frameworks that use interaction history.
• Multi-level decisioning frameworks where interaction history is used by two or more levels of strategies that are defined on different classes.

For the single-level scenario, configure the Dynamic System Setting that sets the pySubjectType attribute when your framework reads interaction history records. The value of this Dynamic System Setting becomes the name of the customer class.

For the multi-level scenario, update the database table for all strategy levels manually. For each level, make sure that the value in the Subject Type column is set to the name of the class for the corresponding strategy. For example, the value for the top level strategy should be set to the name of the class of that strategy.

For more information about interaction history aggregations, see Data Sources landing page

HBase data set type becomes resumable

HBase data set has been enhanced to be resumable. As a result, data flow runs that reference the HBase data set as their primary data source are now resumable. You can pause and resume such data flow runs.

For more information, see the Resumability of data flow runs section in Data flow run updates.

Improvements to support Kibana log viewing

Pega® Cloud resolved a known infrastructure error that prevented customers in AP-southeast-2 region from properly viewing their log messages in Kibana.

Pega Cloud introduced this enhancement as of QI 2018.

View status of custom search indexes

Custom search indexes are special purpose indexes that are created and managed outside of Pega Platform™. You can view the status of custom search indexes on the Search landing page to see whether they are complete. This information is useful for troubleshooting and can help you determine whether to rebuild the index.

For more information, see Checking search index status.

Behavior changes when reporting on descendant classes

Report Definitions that use the Report on descendant class instances option with the Include all descendant classes option apply only to the Applies to Class. Join classes are not included as they were in previous Pega^® Platform versions. The following example shows what happens for each possible scenario for Report on descendant class instances when the report is defined on ClassA with a class join with Work-.

• If Report on descendant class instances is disabled, the report runs against ClassA and the join happens with Work-. The behavior is the same in Pega 7.3.1 as it is in previous Pega Platform versions.
• If Report on descendant class instances is enabled, and Include single implementation class is selected, the report runs against ClassA and the join happens with the MySampleClass implementation class. The behavior is the same in Pega 7.3.1 as it is in previous Pega Platform versions.
• If Report on descendant class instances is enabled, and Include all descendant classes is selected, the report runs against ClassA and its descendants and the join happens with Work-. In previous Pega Platform versions, the join happened with the MySampleClass implementation class.
