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.

Cross-site scripting protection added for parameter page properties
Resolved in Pega Version 8.3.2
An cross-site scripting vulnerability was seen with the Edge browser when run on visibility on client check was enabled with dynamic layouts and some properties were accessed from parameter page. Because run on visibility on client check is not required in this scenario, is has been removed and the values will be accessed from the server instead.

Added safeURL encoding for Japanese characters in attached filenames
Resolved in Pega Version 8.3.2
It was not possible to preview a Japanese-titled PDF file attached on a work object. Investigation showed that in case of Japanese characters, file names were not being correctly encoded during the fetch request when JBoss was used. The retrieval worked correctly under Tomcat. In order to ensure consistent encoding, the safeURL API will be used for constructing the URL and for the activities DisplayAttachFile and pzDownloadFromRepository which add the ContentDisposition header.

Enhanced SSA metrics made available
Resolved in Pega Version 8.6.5
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.

Updated context handling for executing data transforms in dataflows
Resolved in Pega Version 8.6.5
When performing a sort operation in a data transform on a page list and invoking the Data transform through a Data flow, a java.lang.UnsupportedOperationException was generated on the sort step even though the data was correct. Investigation showed that the dataflows were using a different execution context than the context used for regular activity execution. An update has been made to ensure the correct context is being used while executing data transforms in dataflows.

Explicit Kerberos renewal added for HDFS
Resolved in Pega Version 8.6.5
When using WebSphere/IBM with Hadoop connectivity, the Kerberos credentials were expiring after 7 days and causing connectivity failures. Investigation showed the Apache Hadoop HDFS Client was not renewing the ticket even when there were operation calls every few hours. To resolve this, an enhancement has been added to the Pega HDFS client which will explicitly tell Hadoop authentication layer to check for Kerberos ticket renewal instead of relying on Hadoop built-in logic.

Added support for creating predictive models in Production
Resolved in Pega Version 8.6.5
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.

Made CommitLog messages more resilient to class change
Resolved in Pega Version 8.6.5
Persistent class mismatch exceptions were seen while refreshing the ADM models after updating from Pega 8.5. This was caused by changes to the Cassandra adm_commitlog message schema which caused the commit log messages generated to be incompatible with the deserialisation logic present in higher versions of Pega, but as the commit log messages had a time to live of 24 hours the issue self-resolved. However, this has been resolved by setting serialVersionUID for the ModelParameters class so CommitLog messages are now compatible with future minor and patch releases.
