DDS service will not run Hazelcast check if external Cassandra is configured
Resolved in Pega Version 8.2.6
Services were not responding, and thread dumps seen in the logs indicated that a large number of threads were waiting for one to come back from getting the cluster state for a DSM process. Investigation showed that the threads were waiting for a Hazelcast response about the cluster state. However, since a Hazelcast call is not needed when Pega is configured with external Cassandra, the DDS Service code has been changed to not to check for candidate nodes if configured with external Cassandra cluster.

Resolved errors when using Build Model from the Preview Console
Resolved in Pega Version 8.2.6
Using the Web Chatbot interface and trying to perform Build Model action from Preview Console failed with multiple errors, either "This action is not allowed as it is outside the current transaction" or "class <blank> doesn't exist". This was traced to issues with the transaction during model update, and has been resolved by conditionally disabling the show page step of pzGetModelProcessStatus. This step creates a difference in the context of the current transaction and is disabled when called from Update API.

DDS added for automated dataflow run cleanup
Resolved in Pega Version 8.2.6
During a recent upgrade it was seen that there were in excess of 20k dataflow runs, some 2 years old, which slowed down the migration significantly. In order to resolve this, an automated process has been added. This clean-up procedure deletes all the single case, batch, and real time runs older than 30 days which are in the final state - Completed, Completed with Failures, or Failed, and batch and real time runs which are in the Stopped state. The DDS Pega-DecisionEngine.dataflow/run/maxDaysToKeepRuns.should be used configure the retention period. Note that the retention period is calculated since the last processed message and not the creation time of the run.

Revision Management updated for Marketing
Resolved in Pega Version 8.2.6
When Offers created outside of the CR context were deleted from Revision Managment LP using the Delete Rules option, the Offer was deleted but the Decision Data was not updated. This also happened when the offer was not included while submitting the revision. This has been resolved by providing the needed extension for deleting the offer rules in marketing.
