HandleResponses updated for use with optimized campaign
Resolved in Pega Version 8.7
After updating from Pega 8.4, responses were not processed in the pxHandleResponses Data flow if the "pyCampaignOptimization" flag was set to true. This was traced to a missed use case for an optimized campaign, and has been resolved by modifying the condition in HandleResponses.

Existing Kafka topic name used for connection
Resolved in Pega Version 7.4
When running a Kafka dataflow, Pega was using the dataset name instead of the topic name for the topic connection. This has been fixed, along with forcing a capital letter for the first character of the dataset name in order to ensure proper matching.

Updated dataflow used after pause/continue
Resolved in Pega Version 7.4
When using an event dataflow that has a Kafka dataset as the source, running the flow, pausing it, and importing updated rules was resulting in the resumed flow still using the old rules. This was a known limitation in the data flow metrics management where when a run was resumed, the previous metrics were "merged" with new metrics. In cases where the structure of a data flow changed between pause/resume, merge failed silently and new metrics were not saved to the database. The metric management has now been updated to merge metrics correctly: in case of a data flow structure update (e.g. shapes added/removed), after the data flow is run, stage metrics will be cleared up as it is not possible to match them with the new structure, and all other metrics will be properly resumed from the "paused" position (e.g. number of processed records, throughput etc.).

Value Finder updated for use with external Cassandra nodes
Resolved in Pega Version 8.7
Attempting to use the Value Finder feature resulted in the error "Running Simulation is not possible because the required services are not available. Contact your System Administrator to enable the data flow and decisioning data store services." Analysis traced this to a check which identifies whether there is more than one internal node available for CDH/ DSS node. Since there were only external nodes available in this scenario and no internal nodes, the method returned false and returned the error when the CDH / VF page was launched. To resolve this, the check has been modified to allow for external Cassandra.

Special characters escaped for use in "is in List" lookups
Resolved in Pega Version 8.7
After creating a specific criterion on any proposition using a string property, the "Is In List" operator, and a customer list with one value containing a "$", clicking save or check in resulted in the exception error "Problem invoking function: pega_decisionengine_propositionfilterfua.pzPropositionFilterMethodBody--(PublicAPI,ClipboardPage) java.lang.IllegalArgumentException: Illegal group reference at java.util.regex.Matcher.appendReplacement(Matcher.java:857) ". This has been resolved by escaping regular expression control characters in string replacement, which will allow the use of characters such as the $ sign for "is in List" lookups.

Interaction History properly saved when running strategy on a different data flow
Resolved in Pega Version 8.7
Customized Interaction History properties that had been added to pyInteractionHistoryConfiguration and pyDefaultWorkingSet and saved into the PR_DATA_IH_FACT table were not being saved properly after upgrading from 7.3 to 8.3. This was a missed use case and has been resolved.

Enhancements added for very heavy use of strategy decision logic
Resolved in Pega Version 8.5.2
Recent updates were made to improve memory performance for scenarios where a single request primary page had tens of thousands of pages under an embedded pagelist property and the decision logic involved a strategy running on all the pages in that page list. To further improve performance, the array iterator has been modified and a DSS has been added that makes the threshold (50) in SSAExecutionContextIteratorFactory tunable.

Added handling for calling truncate with external Cassandra
Resolved in Pega Version 8.7.1
A JMX exception was generated when using external Cassandra. This was traced to the combination of calling truncate and using external Cassandra for DDS, and has been resolved by adding a 'do not execute' consistency check during a truncate operation when using external Cassandra.

Support added for expression in strategy scorecards
Resolved in Pega Version 8.5.2
When invoking REST against a dataflow that had a strategy containing a scorecard that used an expression and the "Include model explanations option" was enabled in the Strategy configuration, the system failed with the error "PropertyValueInvalid .pxMaxScore Cannot cast the value (unknown) to double". This was traced to the Scorecard explanations failing during serialization when an expression was used, and has been corrected.

External Input setting available on Strategy Batch Performance Test
Resolved in Pega Version 8.7
It was not possible to specify the External Input as part of a strategy when using a Batch Performance test. This has been resolved by updating the pzDisplayTestStrategyContext When condition to "true" the so external input selector is properly displayed.
