Refinements made to MarkerNode memory use
Resolved in Pega Version 8.5
Significant memory usage can be observed when data join in strategies are missing the join conditions. E.g., when the primary source in the strategy can have up to 300 or even more propositions, the join without the join condition would perform a cartesian product with possibly up to 400 or even more records returned. This may cause performance degradation. To guard against this, an update has been made that seeks to prevent repetitive markers being accumulated under a MarkerNode while trying not to rely on any implementation of equality and hashCode for individual marker implementations.

Improved management for table pr_log_dataflow_events
Resolved in Pega Version 8.5
The Lifecycle event table was sometimes growing too large. This additional strain of database transaction volume caused poor performance on the Dataflow tier and lead to cluster instability and time-consuming cluster restarts. Due to problems in one of the Pulse tasks, the Pulse thread was not processing single case metrics properly and causing the unbounded queue for single case to grow. This has been addressed by switching to a fixed queue size, which is configurable with the DSS: dnode/single_case_queue_size. The default value of the DSS is 4000, and if changed a system restart is required. An error will be logged each 1000 queue misses, and metrics will be dropped if the queue is full. In addition, the Pulse task frequency has been improved and managed to prevent interference with other Pulse tasks and will be triggered only if a run is system-paused for a long interval. Rebalances now have a failsafe if something unexpected happens during the Pausing of the run, and If the cluster becomes unstable, the life cycle events logs may be disabled with dataflow/run/events/persist .

Properties persist after revision import
Resolved in Pega Version 8.5
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

DataSet preview will use date instead of datetime
Resolved in Pega Version 8.5
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.

Repaired Tracer use with Google Chrome
Resolved in Pega Version 8.5
After running Tracer while using Chrome, closing it and trying to run another resulted in an error indicating "Cannot Launch multiple tracer sessions for a requestor". This was identified as a bug with Google Chrome Versions greater than 70 and was caused by Chrome deprecating the use of sync XHR on page dismissal, and has been resolved by modifying the system to use a beacon API instead.

API added to sync presence with requestor to clear inactive operator sessions
Resolved in Pega Version 8.5
An intermittent error message was seen indicating the maximum number of active sessions for the current operator had been reached even though there were not multiple logins and there was no requestor displayed in the requestor management landing page. This was traced to sessions that were not properly closed and cleared, and has been resolved by exposing an API that will sync the presence record with the requestor state so inactive sessions will be cleared.

Corrected filedownload extension header issue
Resolved in Pega Version 8.5
Filedownload header contained plain non-ascii characters which caused a security violation issue. This has been resolved by removing the filedownload header from the HTTP response when the sendfile API is used with inputstream to download a file.
