Handling added for special characters in dataflow and mbean name
Resolved in Pega Version 8.7
Exception errors from deleted email listeners were seen after server start-up. Investigation showed that when a dataflow stage name had a special character and that name was then used in the mbean name, it was failing to register. This has been resolved by escaping JMX key values if they contain special characters.

Value Finder updated for use with external Cassandra nodes
Resolved in Pega Version 8.7
Attempting to use the Value Finder feature resulted in the error "Running Simulation is not possible because the required services are not available. Contact your System Administrator to enable the data flow and decisioning data store services." Analysis traced this to a check which identifies whether there is more than one internal node available for CDH/ DSS node. Since there were only external nodes available in this scenario and no internal nodes, the method returned false and returned the error when the CDH / VF page was launched. To resolve this, the check has been modified to allow for external Cassandra.

Prediction outcome response timing updated
Resolved in Pega Version 8.7
Predictions using a response timeout were not emitting a negative response ('NoResponse') when the specified waiting time expired. This was traced to the the outcome and response timeout values being overridden while triggering responses for multi stage predictions along with chained predictions. This has been resolved by modifying the flow to emit each outcome as it is received and by adding the dataflow trigger in the function so that it does not override the values in case of chained predictions.

Tombstone cleanup modified to handle very large volume environments
Resolved in Pega Version 8.7
Cassandra nodes were periodically suffering from an out of memory condition. This was traced to tumbling windows creating too many tombstones for Cassandra to clean up effectively when running in a very high volume environment with a short tumbling time. This has been resolved by modifying the procedure away from using individual tombstones to instead use range tombstones which will continuously supersede the previous tombstone so there is never an opportunity for them to build up.

Performance improvements for action check-in
Resolved in Pega Version 8.7
The process of 'Saving As' an action to a higher ruleset, Saving, and then running Check-in was taking an excessive amount of time. This was traced to redundant page copy activities and performance has been improved by updating the implementation.

Performance improvements for stale thread warnings
Resolved in Pega Version 8.7
Stale thread warnings were causing performance issues during dataflow run execution. Stale thread/slow component warnings are added as part of the dataflow execution when a processing thread takes more than 5 minutes to process a single dataflow record. The stacktrace of the dataflow thread is added as part of the warning for debugging purposes, but in some scenarios the stacktrace can become very large. This has been resolved by removing the stacktraces from the warning, improving the query logic, and adding the run ID to the exception method to assist if there is an error.

Enhancement added for tenant-level authentication
Resolved in Pega Version 8.7
In a multi-tenant PDC with a few tenants that utilize their own custom SSO, a pre-authentication activity inside a tenant that should block community access was also affecting tenants that did not have that pre-auth activity set. This was a missed use case and has been resolved by adding a tenantId hash in SchemePRAuth.makeUniqueSchemeName() to create the authServiceName.

LookUpList correctly executes during SSO login with model operator
Resolved in Pega Version 8.7
After configuring SSO to create operators on fly using a model operator, a new user logging in for the very first time had their operator ID created using the model operator, but after upgrade new users logging in to the system received the error "Only authenticated client may start this activity: RULE-OBJ-ACTIVITY @BASECLASS LOOKUPLIST". This was due to the methods used for additional security on the activity @baseclass LookUpList which allows it to only be run by authenticated users, and has been resolved.
