Work object status correctly set to Resolved after refresh
Resolved in Pega Version 8.6
When using the Refresh option from the Other Actions menu before submitting the flow action, the work object status was not updating to Resolved-Completed. Investigation showed that when performing the Refresh action, the RefreshOnConflicts activity created a Clipboard page named LatestWorkPage with a copy of the work object. This page was not removed after use, causing the Resolved-Completed status to be set on LatestWorkPage instead of pyWorkPage. To resolve this, a step has been added to RefreshOnConflicts to remove LatestWorkPage.

Editing Approval flowshape retains decision tree
Resolved in Pega Version 8.6
Editing the Approval flowshape caused the decision tree to become blank when selecting 'Use Business logic' in the dropdown for "Route to dropdown". This was traced to a missed use case for earlier work done on enhancements for email approver shapes regarding retaining previous values while switching back to using the business logic option, and has been resolved.

RefreshFor correctly returns validation messages
Resolved in Pega Version 8.6
After upgrade, the PUT method on /api/v1/assignments/{ID}/actions/{actionID}/refresh?refreshFor was not returning validation messages on the child level. This was an unintended consequence of refactoring work done on pzApiCreateJsonForField around the default value calculation, and has been resolved. In addition, an issue with read-only text controls not being localized has been corrected.

Updated timestamp handling for duplicate key issue with PyCompleteAutomation
Resolved in Pega Version 8.6
Occasionally a robot failed to complete a case due to a duplicate key exception. This was an issue with the History record creation due to duplicate key erlated to the timestamp, and has been resolved by updating the timestamp handling so that the REST API will use 'getCurrentTimeStampUnique' and for other cases 'pxGetCurrentTimeStampThreadUnique' will be used.

Upload with "Select File" works in Microsoft Internet Explorer
Resolved in Pega Version 8.6
When using Microsoft Internet Explorer, uploading a document was failing on the first try when using the "Select File" button. The second attempt worked as expected. This was an unintended consequence of work done to enable attaching the same file after deleting it, and was related to Internet Explorer calling an "onChange" which caused the "pzAttachFileDDFileList" section which is used to display the attachments uploaded to not be properly refreshed. This has been resolved by updating the pzMultiFilePath control handling of the success and failure of the upload function call.

Improved cleanup for adm_response_meta_info
Resolved in Pega Version 8.6
The adm_commitlog.adm_response_meta_info column family was growing, leading to gradual increase in CPU utilization on the Adaptive Decision Management (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.

Thread contention resolved for InteractionHistoryQuery
Resolved in Pega Version 8.6
High thread contention was observed while running Inbound load tests. This was traced to pzLoadInteractionHistory invoking a generated strategy to retrieve ihFields from InteractionHistoryQuery using the getUsedInteractionHistoryFields() method: because this method is synchronized, it caused a bottleneck. To resolve this, the synchronized methods have been replaced with the appropriate data structures.

Strategy handling updated for very large systems using IH summary
Resolved in Pega Version 8.6
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.

Enhancement added for node heartbeat recovery process
Resolved in Pega Version 8.6
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.
