Nodes cleared on startup to resolve pending joining state
Resolved in Pega Version 8.2.6
ADM nodes were taking a long time to start and ending up stuck in Pending_Joining state. This was traced to a condition where if a node held a lock and restarted, it created a block where others waiting for the lock to be released sat and waited. To resolve this, an update has been added to clear previously held locks on startup.

Real time processing picks up correct datetime for Capture Response records
Resolved in Pega Version 8.2.6
A Realtime Data flow for the Capture Response flow was configured with a strategy shape set to load previous decisions within the past 7 days. Once this Realtime DF was started, attempting to Capture Response for decisions made after that startup timepoint did not work. This was traced to the InteractionID being written with global properties for the datetimes, and has been resolved by making those datetime properties local so the start and end time are not cached and the time range is calculated based on "now”.

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.

Guided tour popups handling added for right-to-left language locales
Resolved in Pega Version 8.2.6
Guided Tour Popups were still appearing in the default EN location after switching to the ar_AR locale. This was traced to a missed use case for locales using a right-to-left mode such as Arabic or Hebrew, and has been resolved by updating the guided tour engine openPopOver function to account for the HTML tag dir attribute for value of "rtl". This will anchor the pop over to rightBottom / and display the arrow on the rightTop instead of leftBottom / leftTop.

Property setting corrected for On Join and Exclusion shapes in Expression Builder
Resolved in Pega Version 8.2.6
The properties for the defined page did not appear when using the type-ahead feature to select properties for the On Data Join and Exclusion shapes in Expression Builder. This was an issue related to the property being referenced for setting the context in the expression builder, and has been corrected.

Updated Decision Table validation for multiple OR conditions
Resolved in Pega Version 8.2.6
When the Decision Table had multiple OR conditions, the table was verified as consistent even when two rows had the same value. Analysis showed that when Show Conflicts encountered multiple 'or' conditions in a row that matched the same conditions in other rows, it considered them to be different rows. This has been corrected.
