DDS service will not run Hazelcast check if external Cassandra is configured
Resolved in Pega Version 8.3.2
Services were not responding, and thread dumps seen in the logs indicated that a large number of threads were waiting for one to come back from getting the cluster state for a DSM process. Investigation showed that the threads were waiting for a Hazelcast response about the cluster state. However, since a Hazelcast call is not needed when Pega is configured with external Cassandra, the DDS Service code has been changed to not to check for candidate nodes if configured with external Cassandra cluster.

Resolved errors when using Build Model from the Preview Console
Resolved in Pega Version 8.3.2
Using the Web Chatbot interface and trying to perform Build Model action from Preview Console failed with multiple errors, either "This action is not allowed as it is outside the current transaction" or "class <blank> doesn't exist". This was traced to issues with the transaction during model update, and has been resolved by conditionally disabling the show page step of pzGetModelProcessStatus. This step creates a difference in the context of the current transaction and is disabled when called from Update API.

Corrected calculating propensities
Resolved in Pega Version 8.3.2
Several PMML models designed to compare the outcomes to a control dataset experienced an issue where the probability scores in Pega did not match the original control dataset. The PMML model was also tested using KNIME; those results matched Pega but not the original control dataset. Investigation showed that the JPMML evaluator contained outdated code, and the incorrect calculations have been resolved.

Added tokenizer for KeyWord-Based Topic Detection phrases
Resolved in Pega Version 8.3.2
KeyWord-Based Topic Detection was not Working for "Enrollment/Re-Enrollment" as a word, for example a categorization model with the text 'This is an email related to Enrollment/Re-Enrollment'. To facilitate this use, a tokenizer has been added to break should, must, and and words into components for a taxonomy match.

DDS added for automated dataflow run cleanup
Resolved in Pega Version 8.3.2
During a recent upgrade it was seen that there were in excess of 20k dataflow runs, some 2 years old, which slowed down the migration significantly. In order to resolve this, an automated process has been added. This clean-up procedure deletes all the single case, batch, and real time runs older than 30 days which are in the final state - Completed, Completed with Failures, or Failed, and batch and real time runs which are in the Stopped state. The DDS Pega-DecisionEngine.dataflow/run/maxDaysToKeepRuns.should be used configure the retention period. Note that the retention period is calculated since the last processed message and not the creation time of the run.

Restart issue on dataflow service nodes resolved
Resolved in Pega Version 8.3.2
A high percentage of rolling restarts were failing for nodes hosting dataflow services due to prolonged restart times. To resolve this, the system has been updated so Cloud services will not try to recover the node state in case of a restart, since nodeIDs are always new and not reused.

OpenRuleAdvanced updated
Resolved in Pega Version 8.3.2
After upgrade, the Update Page and Append and Map to step in Data transform was generating the error "No Server connection while giving page name to Target and Source". This was traced to the OpenRuleAdvanced_OverLabel control, and investigation showed that a variable was not being resolved when invoking pzEncryptURLActionString. This has been resolved by updating OpenRuleAdvanced and reimplementing two parameters as well as moving the call of these variables to the beginning of the script. Security has also been improved by moving some of the encryption to SafeUrls.

Route to configuration in the approval flow accepts Specific User parameters
Resolved in Pega Version 8.3.2
Route to configuration in the approval flow was not accepting a parameter value/property value when select Specific User option from drop down was chosen. This was traced to unique ID change work done in the 8.2 release: the pzSimpleApproval section has two controls (DropDown for Participant & AutoComplete for Operator) configured on same property pyOperatorToAssign with "run visibility on client configuration), and when the control value was being changed in the AutoComplete control, the empty value of DropDown control was being posted to the clipboard. To correct this, the section Work-.pzSimpleApproval has been modified to remove performing run-visibility conditions at client side. Instead, the system will use the ".pyApproverType Changes" condition to refresh the wrapper DL which contains the routeTo type Operator/WB/Participant property controls.

ApplicationInventory function deleted
Resolved in Pega Version 8.3.2
It was possible to call the activity "ApplicationInventory of class Rule-" by appending the activity name in the URL. To improve security, the ApplicationInventory activity and HTML rule have been removed from the system.
