Data Transform added to support Kafka custom serialization/deserialization
Resolved in Pega Version 8.5.1
Previously in a Kafka DataSet it was possible to either serialize or deserialize messages as mapped objects to JSON, or to implement some other mechanism to achieve the expected results. An enhancement has now been added to the Pega platform functionality: DataTransformSerde will be available to be used as custom serialization/deserialization mechanism in Kafka DataSet.

Improved cleanup for adm_response_meta_info
Resolved in Pega Version 8.5.1
The adm_commitlog.adm_response_meta_info column family was growing, leading to gradual increase in CPU utilization on the ADM nodes over time. Investigation showed that the compaction on the adm_response_meta_info table was not being triggered by the ADM service, and the compaction did not remove rows that belonged to models that had been deleted. To resolve this, compaction of the adm_response_meta_info table has been moved from the ADM client nodes to the ADM service nodes, which will correctly trigger the compaction on a predefined schedule. The compaction logic has also been refactored to remove rows that belong to models that have been deleted.

Performance improvements for very heavy use of strategy decision logic
Resolved in Pega Version 8.5.1
Updates have been 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 involves a strategy running on all the pages in that page list. These include modifications to GetFramesSSA to create reusable frames under heavy load conditions that contain the information about all the primary pages that it has to iterate; if CallSsaProgram receives one of these special frames, it will use it invoke the program by repurposing it with a new primary page at each iteration.

Strategy handling updated for very large systems using IH summary
Resolved in Pega Version 8.5.1
When a Strategy in a Real-time dataflow used IH Summary on a system with more than 5000 groups for one eventKey, the message "Error retrieving aggregates from Cassandra KVS" intermittently appeared. Investigation showed that if the number of result rows was greater than the FETCH_SIZE (set to 5000), it meant another read to Cassandra was required and an exception was generated. To resolve this, updates have been made so that instead of returning maps, the system will return iterators and change them to map on the calling thread.

New security role added to restrict access to development-specific classes
Resolved in Pega Version 8.5.1
A new security role and related RAROs have been implemented to allow better security for end users on non-BAC systems. This restricts access to Rules and execution of activities on classes that are development-specific.

Operator created with save-as has correct application access
Resolved in Pega Version 8.5.1
Creating an operator using Save As retained access to the applications of the original operator even if they were removed in the creation process. This was due to the saveAs operation of the Operator not retaining consistency between the records in the ValueList pyAccessGroupsAdditional and the page list pyaccessgroups_opid. To resolve this, the PreSaveAs of the Operator ID has been updated to maintain consistency in the records.

Correct manager name retained for skill-based routing updates
Resolved in Pega Version 8.5.1
In App Studio, having a manager update a team member's skills changed that team member's reporting Manager name (.pyReportTo) upon save. This was a use case where multiple operator IDs were required for the same person (name and email), so that using the report definition parameter 'BestOperatorValue' for the pzUpdateOperatorInfo activity caused an incorrect manager name to be set to the team member's operator ID. This has been resolved.

Delegated Decision table rule grid loads in iFrame with SSO
Resolved in Pega Version 8.5.1
The delegated decision table rule grid and checkout options were not displayed when launched from iFrame using SSO sign in. Without SSO, the delegated decision table grids were loading properly for the same Access group. The heart of this issue was that decision tables were using an older style of Designer Studio javascript which was not designed to be embedded in an iFrame due to issues related to Cross-Origin Resource Sharing (CORS). In order to support the usecase of the Pega end user portal/application being integrated to an external domain application using an iFrame, enhancements have been made to the necessary delegated rule function definitions.

Tracer toolbar shows correctly in IE
Resolved in Pega Version 8.5.1
After upgrade, the developer toolbar for the tracer pop up was not visible in Internet Explorer. Investigation showed that Microsoft Internet Explorer was loading the correct elements, but they were not displaying due to recent updates made to prevent Cross-site scripting vulnerabilities for the tracer. This has been resolved.

Resolved errors when refreshing test case
Resolved in Pega Version 8.5.1
On refreshing any test case for decision tables, a "rule no longer exists" error appeared on screen and a pzRuleNotFound exception was generated for all testcases in tracer. This was traced to Rule-Utility-Function lookup parameter handling in the pzGetFreshLabelForRUT decision table: because the Rule-Utility-Function was not able to fetch the label and the caller step in an activity, it was ending with a fail status and generating the errors. This has been resolved by correcting the Rule-Utility-Function calls in the decision table pzGetFreshLabelForRUT to ensure it has the correct parameters.
