Delayed Learning works correctly with Volume Constraints
Resolved in Pega Version 8.5.6
When running an outbound campaign using NBA Designers predictions and delayed learning in conjunction with volume constraints, the adaptive models ended up with incorrect feedback if the prediction had an Alternative label configured with a defined waiting window. This has been resolved with the addition of a new flag 'isVolumeConstraintEnabled' during dataflow creation which will check for volume constraint, and a filter in HandleResponses for that flag.

Empty string handling added to SSA CompareDates
Resolved in Pega Version 8.5.6
The CompareDates implementation in SSA has been updated to fallback to the current datetime/date if it encounters empty string arguments.

Performance improvements for stale thread warnings
Resolved in Pega Version 8.5.6
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.

Decision Management book updated for additional NLP troubleshooting
Resolved in Pega Version 8.5.6
Troubleshooting articles have been added to the Decision Management book which address the most common issues encountered when working with the NLP capability of Pega Platform, including topic and entity detection and email parser. These tips can assist with issues such as a node running out of memory due to having a large number of custom Ruta scripts that use REGEX pattern matching.

Addressed performance issues for classless DSMClipboardPage
Resolved in Pega Version 8.5.6
The DSMClipboardPage implementation handles Page Group access as a classless page (i.e. pxObjClass = ""), creating potential performance issues in implementations where the page group is used with a very large number of distinct AccountIDs in a short period. This has been resolved by updating the system to not cache keys for page group classless page.

Resolved error for custom relative dates
Resolved in Pega Version 8.5.6
An error was seen when parsing the [Date Property] [is before/after] [Last/Next x days] while using a custom amount of number of days in Customer Decision Hub (CDH). This was due to the system not supporting the [Last/Next x days] feature for SSA, but only detecting this during parsing for the prefixed values for Proposition Filters and not custom values. As the parser did not realize the construct referring to the relative date was not supported, it created an SSA that caused an exception during execution. This has been resolved.

Modified batch requestor handling to ensure cleanup
Resolved in Pega Version 8.7.2
A large buildup of batch requestors was seen, and restarting the node did not clear it. Investigation showed that in the case of one class reading a DSS value, a Pega requestor was being created when it was unable to retrieve any Pega context, and this requestor was not cleaned up afterwards. To resolve this, an update has been made to the way the requestor and Pega context is being created along with ensuring it will be cleaned up properly after use.

PMML updated for nested 'if'
Resolved in Pega Version 8.7.2
Running a model on the openscoring API and the Pega PMML model gave different results. This has been resolved by updating the handling for nested 'if' in PMML.
