Exception handling added for ClipboardPropertyCollection
Resolved in Pega Version 8.7
After upgrading from Pega v7.3 to 8.5, validating the existing strategy logic generated the error "ClipboardPropertyCollection is not a supported ILType". This was traced to the special Pega expression type PropertyCollection not being supported by IL, and has been resolved by adding logic that will throw a more appropriate exception (instead of the generic PRRuntimeException) so the event can be caught by the existing fallback logic.

Added handling for MS SQL datestamp format
Resolved in Pega Version 8.7
When using an Microsoft SQL Server, the browse operation was failing with an SQL error for the pyIHSummary dataset. Investigation showed there were some datasets that generated SQL statements with a date timestamp format that SQL was not able to handle implicitly, affecting browsing but not functionality. This has been resolved.

Multistage Prediction Logic improved
Resolved in Pega Version 8.7
When Predictions with Response wait time configured were executed as part of make decision, each decision that came out of the strategy caused a pxDR call to fetch the relevant model execution results and process them to stage the default outcome results for models. This has been improved by modifying the system to process the existing records rather than reading data again from pxDR.

Strategy execution queries tuned
Resolved in Pega Version 8.7
During NBA strategy execution, interaction history summaries were queried multiple times for a single strategy execution. To improve this function, the isChanged query will now be executed once after system startup if there are no changes instead of being executed every time the Aggregates DataSet BBK is executed. If the same Aggregates query is made multiple times as part of a Strategy in a REST request (i.e. likely multiple ADM models in a MakeDecision call), only one Aggregates BBK call will be made.

Predictive model snapshot generation updated for Java 11
Resolved in Pega Version 8.7
While the Simulation data export case type was executed as expected, the predictive stages showed zero records processed. This was traced to instances running on Java 11 which caused an issue with the snapshot process. This did not affect learning, but visualization and reporting were not working in Prediction studio. To resolve this, an update has been made to the snapshotID for Java 11 compatibility which will generate a random UUID instead of using a seed.

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.

Updated entity attachment extraction tokenizers
Resolved in Pega Version 8.7
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 8.7
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.
