GET API will consider case locking mechanism
Resolved in Pega Version 8.7.1
After update, performing a GET call on an assignment was unexpectedly locking the case. This was traced to a difference in handling: Pega 8.3 performed an Obj-Open-By-Handle of the workobject without acquiring a lock, while Pega 8.6 calls Assign-.acquireWorkObject which acquires a lock on the work object thereby affecting the other requestors from accessing the case. This has been resolved by enabling ConsiderLockingMode to independently determine the locking mechanism set for the case type.

Adaptive model retry mechanism enabled
Resolved in Pega Version 8.5.6
Adaptive models were missing from the Model Management page as well as in the Prediction studio while similar models for the same proposition, only differing by the Channel name, were visible. This was traced to data not being synchronized between the database and Cassandra. The pegadata.pr_data_adm_factory database table did not contain the record of the missing channel, but Cassandra did. Since the current Cassandra adm_scoringmodel contained model information, the system still believed the model was present. In order to ensure Cassandra and the database table are in sync, an update has been made to enable the retry mechanism "SyncFactoryKeysTask" to create the ADM model in factory table by periodically looking for scoring models without factories or an entry in adm_meta.

Handling added for clearing node killed between assignment and processing
Resolved in Pega Version 8.5.6
An Offer flow was not resuming after it expired according to the wait shape. Investigation traced this to partitions which were assigned to a dead node in NEW state where they were not picked up by the dataflow. The problem was only encountered in the unusual situation when a dataflow node was killed in the brief period of time between the assignment and the processing, and has been resolved by adding an update which will clear unknown new assigned partitions for the batch run health task.

Added handling for DSM Services stuck in leaving status after database outage
Resolved in Pega Version 8.5.6
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.

Modified batch requestor handling to ensure cleanup
Resolved in Pega Version 8.5.6
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.

Resolved error during save of a Predictive Model
Resolved in Pega Version 8.5.6
Attempting to save a predictive model in Prediction Studio resulted in the error ".pyModelProcess.pyShapes(Setmodelcontrolgroup).pyMOName: Cannot generate the component ID from the provided input. Enter at least one alphabetic character." This was traced to previous work done around defining a control group using a property reference, and has been resolved.
