Updated COUNT logic for strategies with ssavm set to true
Resolved in Pega Version 8.3.3
An error was seen when attempting to save a strategy after setting ssavm to true, indicating an issue in the “COUNT” method in Group By shape. Since the source field is not used and does not need to be evaluated here, the system has been updated to ignore the source field if the operation is COUNT.

Decision table and tree obey allow missing properties checkbox
Resolved in Pega Version 8.3.3
Calling the decision table/tree inside another decision table/tree which has a missing property was throwing an error even though the "AllowMissingProperties" checkbox was enabled in the caller activity. Analysis showed that the setting for AllowMissingProperties did not carry into any subsequent DecisionTree/DecisionTable calls from the top DecisionTree/DecisionTable, and this has been resolved by modifying the decision table and decision tree obtain value functions to pass AllowMissingProperties.

Added handling for DSM Services stuck in leaving status after database outage
Resolved in Pega Version 8.4.6
During a database outage, the heartbeat would fail and DSM services would eventually try to enter safe mode and stop. As the first step they would try to change the state to LEAVING, but because the database was down saving the LEAVING state failed and the exception was not handled correctly. This resulted in the rest of the stop operation logic not being executed and the service being stuck in LEAVING. To resolve this, an update has been made to ensure the service goes to LEAVING_FAILED if anything fails during the stop operation including when setting state to LEAVING_FAILED. The state LEAVING_FAILED will get flushed to the database eventually when it comes back up. This will allow the aggregation service to start from the LEAVING_FAILED state and recover by itself after a database outage.

Interaction History properly saved when running strategy on a different data flow
Resolved in Pega Version 8.4.6
Customized Interaction History properties that had been added to pyInteractionHistoryConfiguration and pyDefaultWorkingSet and saved into the PR_DATA_IH_FACT table were not being saved properly after upgrading from 7.3 to 8.3. This was a missed use case and has been resolved.

Write lock check added to avoid thread contention
Resolved in Pega Version 8.4.6
After updating the Pega platform and NBA Designer, a significant drop in performance for multilevel strategies was observed. Investigation showed that invoking a sub strategy containing external input intermittently caused a thread contention issue related to write lock. This was traced to overzealous write locking of a component where only a read lock for the thread was required, and has been resolved by adding a verification check to determine whether a write lock is necessary for a given operation before acquiring it.

Localization added to DelegateDescription
Resolved in Pega Version 8.4.6
Localization was not working correctly for the description of a delegated rule due to pyDelegeteDescription being defined with a non-localized Property value. This has been resolved by localizing the property value for pyDelegeteDescription.

Performance improvements for action check-in
Resolved in Pega Version 8.4.6
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.

Updated entity attachment extraction tokenizers
Resolved in Pega Version 8.4.6
After creating an entity extraction model, it was seen that one of the entities worked when there was a space after the semicolon but the detection was not working if there was no space. This has been resolved by updating the Tokenizers with extra examples to address tokenization when ":" is present between two words without any spaces.

Unused DSS compiledExpressions now defaults to false
Resolved in Pega Version 8.4.6
After updating from Pega 8.2 to Pega 8.5, executing a test campaign failed with an error in logs. This occurred when running Distribution tests with "Include funnel analysis reports" checked, and was traced to the DSS setting "decision/strategy/ssaVM/compiledExpressions". As this was previously used to toggle a feature which is no longer in use, the default setting for this DSS has now been changed to false to resolve this issue.
