Corrected unreleased database connections
Resolved in Pega Version 8.6
When using a custom activity that calls Dataset-execute on a database table dataset, the DSS Pega-Engine.prconfig/classmap/usemergestatement/default was set to false and the prepared statement for database table dataset was failing. Upon the failure, an exception was generated that prevented the database connection from being released. This has been corrected.

Node stability improved when adding relevant records
Resolved in Pega Version 8.6
A node was going down after maxing out the database connection pool whenever the inbound service call was invoked. This was traced to several relevant record-related database queries being invoked within a short time for marking 'when' rules referenced in the proposition filter rule as relevant records. This has been resolved by adding 'when' rules as Relevant Records based on a DSS and not adding auto-generated 'when' rules at all.

Queue Processors made more robust
Resolved in Pega Version 8.6
After upgrade, multiple queue processors were not running as expected. Attempting to restart them generated an error. Investigation showed that the real time data flow runs were not picking up or accepting assignments because the local node was under the impression it was still processing data. In this case, the need to synchronize the state of multiple threads caused the queue processors to become stuck in an initializing state due to a race condition that caused the data flow engine to think this run still had threads running when all threads were already stopped. To resolve this, the callback handling has been simplified and made more robust. In addition, in some cases the data flow leader node would believe the service nodes did not accept assignments even when they did. This occurred if many runs and nodes were involved, and was traced to an implicit limit on the NativeSQL query used to read the data to see which assignments were accepted. To resolve this, the key-value store in the Service Registry has been modified to allow a query of more than 500 entries at once.

Import UI option updated to handle data import for upgrades
Resolved in Pega Version 8.6
After upgrade from Pega 8.1 to 8.5, importing data into the datasets using the Actions->Import UI option was not working. This was due to the previous save operation used in import being deprecated, and has been resolved by instituting a new save operation in import to handle this scenario.

Unescaping characters implemented for expressions
Resolved in Pega Version 8.3.6, Resolved in Pega Version 8.4.4, Resolved in Pega Version 8.5.3, Resolved in Pega Version 8.6
An issue where expression builder statements were evaluated differently at runtime than at testing has been resolved. Pega Platform expressions with String literals(that is, sequences of characters enclosed in quotation marks) now unescape characters in strategy shapes such as Set Property or Filter.

Handling added for missing expose.accessGroup property
Resolved in Pega Version 8.6.4
After exposing an existing page group and page list properties along with single value properties using a declare index, running the Column Populator tool prpcServiceUtils to populate the historical data resulted in the single value properties being updated in the exposed column properly, but the page group and page list properties were not updated in the declare index table. On new case creation the declare index tables were updated. This was traced to the default expose.accessGroup not being set for the user, and has been resolved by adding a check and handling that will add the missing property in prpcserviceutils.properties defining the access group for the Rule-Declare-Index of the classes being exposed if it is not present.

Warnings pull from report definition page
Resolved in Pega Version 8.6.4
When a report definition filter was used in the "Class instances to include" section of the Product rule, severe warnings appeared noting "Report definition filter performance issues for LookupDataMigration : Using a custom HTML control to format a column may result in poor performance displaying query results. Consider using auto-generated HTML controls". However, the report definition used, LookupDataMigration, has no Custom HTML control in the latest version of the rule, and the "CheckForWarnings" rule for the product was running a report definition in the "Index-Warning" class which has the warnings for all the versions of the rule. This was due to warnings being displayed in the product for the report definition filter without applying rule resolution for report definition, resulting in warnings from all report definition version rules from a ruleset given a report definition name. This has been resolved by adding an update which will use Obj-Open to read the warnings from report definition page instead of looking up for warnings from Index-Warnings table.

Pega Keystore supported for hotfix signature verification
Resolved in Pega Version 8.6.4
In order to support custom trust managers which require an alternate method for supplying the root certificate via a platform trust store, an enhancement has been added to allow Pega Keystore to be used as a hotfix verification source. Detailed information on this can be found in https://docs.pega.com/keeping-current-pega/87/verifying-hotfix-authenticity-using-pega-keystore

Patchdate values made unique
Resolved in Pega Version 8.6.4
The hotfix manager was incorrectly indicating that a previous hotfix was not installed or was partially installed and should be reinstated. This scenario was created during security updates where the missing/incomplete hotfix had been deliberately deleted from the database, and has been resolved by adding an update which will force patchdate to be unique when adding duplicate code resources during tests.
