Locking and classmap improvements
Resolved in Pega Version 8.5.2
Threads were getting stuck inside classMap and tableInformationMap, causing nodes to go down. This was traced to issues with classmap performance and locking, and has been resolved by replacing the lock library with a newer version and refactoring the tableInformationMapImpl class to use a concurrent hashmap instead.

Updated Tracer for cluster events
Resolved in Pega Version 8.5.2
When running the tracer from the Admin Studio Listener management landing page, Tracer was always fetching data from one node only even though events were generated on another node. This was due to the specific node where the Listener was running being passed to the concern activity while launching the tracer; the Tracer Client node did not have data to check if the event was being populated on another node, and the result was to always fetch data from one node only even though events were generated on another node. To resolve this, the web node ID where the event is running will be passed.

Correct circumstanced version of portal loads
Resolved in Pega Version 8.5.2
Desktop users were seeing the mobile circumstanced version on the application portal immediately upon login. This was a missed use case for a user logging into a mobile portal first and then into a desktop, caused by data between the two sessions being shared in an invalid way. This has been resolved by updating the save work in progress feature to prevent UI data from being shared between mobile and desktop.

Improved resolved rules cache
Resolved in Pega Version 8.5.2
When Rule resolution iterated over a candidate list to fetch a candidate, performance issues were seen on very large sites. To resolve this, an enhancement has been added that will cache the resolved virtual table entries to optimize performance in high demand use cases like DSM.

Hazelcast will be used to determine node presence
Resolved in Pega Version 8.5.2
When calling logoff from the end user portal, sporadic PresenceStandardLifeCycleListener exceptions were seen during high load periods. This was traced to changes made in the Service Discovery behavior: when there is an issue with the node and heartbeats are missed, the node goes to Safe Mode. This caused the topology to change and trigger clearing off presence sessions, but the node still received service requests and this issue was seen. To resolve this, an updated has been made so the system will rely on the Hazelcast listener instead of service discovery to determine whether a node has left.

Handling added to ensure proper Data-Admin-DB-Table name records
Resolved in Pega Version 8.5.2
As part of property optimization, After exposing the property "SolutionName" using the wizard, the value was not visible in a new column for existing records after the completion of the column population job. This was traced to an issue with DBSchemaDDLExecutor expecting lowercase Data-Admin-DB-Table names, and the wizard has been updated to ensure Data-Admin-DB-Table name records are all lowercase.

Updated LegacyPageAdapter with forward links
Resolved in Pega Version 8.5.2
After upgrade, attempting to submit an assignment from an existing case type did not work, and the message "There was an error processing the 'ValidateTechnicalData' step [(no task)]: java.lang.ClassCastException: com.pega.platform.clipboard.adapters.internal.LegacyPageAdapter cannot be cast to com.pega.pegarules.data.internal.clipboard.ClipboardPageImpl" appeared on screen. Investigation showed that a reference forward link was unexpectedly referring to a LegacyPageAdapter. This has been resolved by implementing get/setNamedPageReferenceForwardLinks in LegacyPageAdapter so LegacyPageAdapter can be cast to a ClipboardPageAPI.

Data-Summary reports default will not use the rule resolved setting
Resolved in Pega Version 8.5.2
An intermittent issue was seen where a query could become stuck for ~2 hours in the database. This has been resolved by setting the default for Data-Summary reports to not use the rule resolved setting.

HTML Tags stripped from text email body
Resolved in Pega Version 8.5.2
The Service Email message data section was showing HTML tags in the email message body for both 'prefer-HTML' and 'prefer-inline' where the body was missing. Investigation showed there was no default feature for segregating the markup tags and providing the plain text when ‘HTML’ format was selected in Outlook. This has been resolved by adding a Prefer: outlook.body-content-type="text" header to get the message without HTML tags.
