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.

Enhanced SSA metrics made available
Resolved in Pega Version 8.7.3
In order to better diagnose delays related to the time when a Campaign is scheduled to start and the time when the Dataflow actually starts to run, an update has been made which will generate detailed metrics to cover some of the strategy execution key performance intensive areas. Additional lower level internal metrics related to SSA engine execution have also been made available by way of a DSS to collect more runtime insight for diagnosis. To enable the collection of these Level 2 SSA internal metrics, set the dataflow/shape/strategy/detailed_metrics/level2 DSS in the Pega-DecisionEngine rule set to 'true'. A comprehensive set of enhanced metrics will be available in Pega 8.8.

Added support for creating predictive models in Production
Resolved in Pega Version 8.7.3
While creating a new predictive model rule in Prediction studio, the case was going into broken process after selecting the template with the error message "Error loading D_ProjectList , Reason : No databases defined in properties file:/databases.properties". This was an unexpected use case for creating models in Production level, and has been resolved by updating the flows to turn off the draft mode in this scenario.

DSS introduced to control DSM clipboard page serialization
Resolved in Pega Version 8.7.3
When using a Kafka dataset to consume a message from an external topic that had an attribute name with a special character contained in a page list structure, using a JSON data transform for the mapping in a realtime dataflow resulted in the error "Exception in stage: KafkaDS; LegacyModelAspectInvokableRuleContainer.invoke-Exception encountered a :java.lang.UnsupportedOperationException." To resolve this, a new DSS dataset/CLASS_NAME/DATASET_NAME/JSONDataTransform/deserialization/useDSMPage has been introduced. When the value is set to true, the process will follow the previous behavior of DSM clipboard pages being generated when Kafka records are deserialized using JSON data transform. When the value is set to false, the JSON data transform will generate regular clipboard pages and convert them later to DSM clipboard pages. This would avoid errors when a JSON data transform calls methods from the Clipboard API that are not implemented by DSM pages. This DSS is set per data set instance. CLASS_NAME and DATASET_NAME are placeholders which should be replaced by data set's pyClassName and pyPurpose property values. In addition, a similar DSS, dataset/CLASS_NAME/DATASET_NAME/JSONDataTransform/serialization/useDSMPage, has been introduced for serialization.

Text analytics character limit set to avoid memory issues
Resolved in Pega Version 8.7.3
Utility nodes were unstable related to searching, and email listener threads became stuck during Rule-based Text Annotation (RUTA) and natural language processing (NLP) work on incoming emails. This happened when the system experienced high memory consumption or exceeded memory usage when using text analytics. This has been resolved by setting the default maximum character limit for NLP analysis to 25,000 characters to avoid RUTA memory issues. If text is provided > 25,000 characters, the system will consider only the top 25,000 characters and a flag will appear on NLPOutcome to indicate text has been limited. This character limit is configurable, but if the configuration is set in excess of 25,000 a warning will be shown prior to saving the change.

JMX authentication enabled by default for embedded Kafka and Cassandra
Resolved in Pega Version 8.7.3
For on-premises clients, a potential vulnerability for a Remote Code Execution using the JMX interface on Cassandra and Kafka using exposed network ports has been mitigated by enabling JMX authentication by default for embedded Kafka and Cassandra.

Cassandra startup calls reordered to avoid deadlock
Resolved in Pega Version 8.7.3
Nodes received a service request but it became stuck. This was traced to a deadlock related to CassandraSessionCache.getSession, and has been resolved by reordering the method calls used to initialize the Cassandra session to delay adding the session change listener and avoid a deadlock scenario.
