Large flow handling improved for IE8
Resolved in Pega Version 7.1.7
When opening a large flow in IE8 which includes multiple sub flows, a long-running script warning is displayed. This is caused by too many calls being executed at once on IE8, and has been remedied by turning on the asyncProcessing parameter for IE8.

Corrected swim lane routing with shapes
Resolved in Pega Version 7.1.7
While using swim lanes, adding shapes into the flow caused unexpected and random behavior of the process modeler including failure to return control to the user after saving. This error was related to routing handling when swim lanes are present, and has been corrected.

Resolved issues with Flow shapes distributed across Swim Lanes
Resolved in Pega Version 7.1.7
Pool size is maintained as both pixels and inches, but auto conversion was failing if the pool dimension was very large. This created an error where saving a flow rule could cause the pool to drastically shrink (for example, 20 inches becoming 20 pixels). In order to maintain the proper dimensions, a check has been added for pool and swimlane to ensure the proper inch/pixel conversions.

Update Handler will not run during migration
Resolved in Pega Version 8.4.1
Rolling restart of DataFlow, ADM ,VBD, and Util Tiers failed with a PENDING_JOINING error after an in-place upgrade. This was traced to the logic for the update timing: when nodes start after an upgrade from 7.x to 8.x they will migrate data flow runs. Migration happens on only one node, and while it's in progress the other nodes will wait until migration finishes before they come up. At this point the state of the data flow services will be 'PENDING JOINING'. The issue is that while migrating runs, the Data Flow Update Handler was triggered to validate whether there were nodes available on the service the run belongs to. This call can cause the corresponding data flow service to be initialized, but the call will be blocked since all services wait for the migration to end. This resulted in a deadlock which prevented all nodes from coming up successfully. To resolve this, the process has been updated to skip the update handler during migration to avoid triggering the initialization of client services that are waiting on the migration lock.

DDS service will not run Hazelcast check if external Cassandra is configured
Resolved in Pega Version 8.4.1
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.

Corrected calculating propensities
Resolved in Pega Version 8.4.1
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.

DataSet preview will use date instead of datetime
Resolved in Pega Version 8.4.1
While using a DataSet preview functionality, the date appeared as reduced by one day. This has been resolved by parsing date as 'date' instead of 'datetime' to avoid issues with timezone interactions.

Added tokenizer for KeyWord-Based Topic Detection phrases
Resolved in Pega Version 8.4.1
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.

Properties persist after revision import
Resolved in Pega Version 8.4.1
"When properties were added to a form, they sometimes disappeared after revision import even though the properties always remained visible in a strategy. Investigation showed that the Form changes made in a DD rule were not properly updated in the pyEditElement section. To correct this, logic has been added to handle the form changes in the DD in the following activities:Data-Rule-Summary.pyMergePropositions Data-Rule-Summary.pyRemoveDDRules Data-Rule-Summary.pyWithdrawDDChanges Data-Rule-Summary.pyRemoveRestoreDDRule"
