Handling added for comma value in FusionCharts XML
Resolved in Pega Version 8.4.4
After creating a Summary Report through the report browser and adding that report to the Dashboard, clicking on the report to drill down generated the error "Can't open the rule with the specified keys". Investigation showed that if a category or series in a Report Definition chart contained a comma, the drilldown would not work because of an incorrect pyclassname being passed. This was traced to the use of XML to configure the chart: the FusionCharts third-party library parses the link XML incorrectly and splits JS arguments at any comma. This was a missed use case for having a comma in the name, and has been resolved by adding encoding for the comma value in pzMultiSeriesData FusionCharts XML rule. Then this will be decoded in the drilldown JS APIs pzPega_chart_legacydrilldown and pega_report_summary.

Added accessibility to Report view context menu
Resolved in Pega Version 8.4.4
When on the My Reports screen and a Summary report is selected, the Report Viewer displays a Summarized Reports table with a column header that opens a command menu upon right-click of the mouse. This functionality is enabled in the Report Definition rule by selecting the checkbox Enable column command menu under the Report Viewer tab. Although keyboard users can open the menu via Shift+F10, keyboard users who cannot see the screen were not informed that this functionality is available as the screen reader did not announce this. This has been resolved.

Unescaping characters implemented for expressions
Resolved in Pega Version 8.3.6, Resolved in Pega Version 8.4.4, Resolved in Pega Version 8.5.3, Resolved in Pega Version 8.6
An issue where expression builder statements were evaluated differently at runtime than at testing has been resolved. Pega Platform expressions with String literals(that is, sequences of characters enclosed in quotation marks) now unescape characters in strategy shapes such as Set Property or Filter.

Enhancement added for node heartbeat recovery process
Resolved in Pega Version 8.5.1
Nodes were not showing up in the admin portal even though they were up and running and could be seen in the pr_sys_statusnodes table. The exception "An exception was encountered while invoking the cluster membership listener callback" was seen. All nodes became visible again after multiple restarts. The root cause was traced back to a temporary database connectivity problem. The database itself was fine according to database monitoring reports, but a network problem, a slow database query, or another issue prevented Pega from establishing a connection for more than a minute. An enhancement has been made to resolve this: if a node becomes unhealthy due to the service registry missing due to a failed heartbeat, the heartbeat will try to recover after 60 seconds and keep trying every 30 seconds until it succeeds.

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.
