Email listener update for Microsoft Exchange server
Resolved in Pega Version 8.5.2
After upgrade, TooManyObjectsOpenedException/MapiExceptionSessionLimit errors were seen when starting the email listener. Investigation showed that when the listener was started, two sessions were getting opened and then not closed properly. This was a method originally intended to allow the system to re-use the session to minimize performance overhead, but it is not well-suited for use with Microsoft Exchange server as the Exchange server is unable to cleanup idle sessions. As a result, too many MAPI sessions were opened and led to an authentication exception while opening additional sessions. To resolve this, an update has been made so the system will close the session while the listener sleeps. This stop, restart and graceful shutdown scenario for single threaded email listener scenarios will create a new session every time and close it properly.

Fallback added for calculating date after upgrade
Resolved in Pega Version 8.5.2
After upgrade, the date value returned from Stored procedure failed to be mapped to "date" type property. Stored Procedure was used to get data from an external Oracle database and then handed to a Data Transform to map the values. When the Data was fetched from the store procedure, the date properties were mapping correctly, but when these values were mapped from the clipboard into the usecase using a Data Transform, the data for date properties was becoming corrupted. This was traced to logic differences between the versions: 8.2 generated resolveToDate while in 8.5 generates resolveToBigDecimal. In this case, resolve to big decimal was being called with aType='D' and aValue=20200918, and the 20200918 number was being interpreted as days since 1 Jan 1970 instead of as a date. This has been resolved by adding a fallback for the date calculation.

Unneeded AUC error percentage calculation removed for better system performance
Resolved in Pega Version 8.5.2
When generating snapshots of the ADM models, an inefficiency in the metric calculation for the AUC error percentage caused an excessive amount of memory to be allocated which could cause slowdown or require a system reboot. This has been resolved by removing the problematic AUC error percentage calculation as it is not used in the UI.

Rollback filter query updated to handle very large classes mapped to the same history table
Resolved in Pega Version 8.1.4
When rolling back the imported product file using deployment manager, the error "DatabaseException caused by prior exception: org.postgresql.util.PSQLException: ERROR: column "pzinskey" does not exist" was seen. This was traced to the rollback process picking the already processed items from the history table due to an incomplete filter query that occurred when there were more than 1000 classes mapped to same history table. This has been resolved.

Improved resolved rules cache
Resolved in Pega Version 8.5.2
When Rule resolution iterated over a candidate list to fetch a candidate, performance issues were seen on very large sites. To resolve this, an enhancement has been added that will cache the resolved virtual table entries to optimize performance in high demand use cases like DSM.

Create Survey routes case correctly
Resolved in Pega Version 8.5.2
The Create Survey utility was not routing the case to the user who initiated the case, but instead was routing it to the user who checked-in the case. This was traced to an error related to pxRequestor.pxUserIdentifier in the data transform pzpopulate survey params which is called when the survey utility is used, and has been corrected.

Corrected tooltip evaluation for multiselect
Resolved in Pega Version 8.5.2
After adding help text for a multiselect help icon with overlay on hover field, the value was not being sourced. Changing to a different type of help text or control type worked as expected. This was due to an error in case sensitivity, using pyToolTip when it should have been pyTooltip, and has been corrected.

Rule lock is released after alternate approved operator rejects it
Resolved in Pega Version 8.1.4
When using the rule check-in approval process, if a rule check-in candidate was rejected by an approved operator other than the one who checked it in, the lock on the original rule was not released. This has been corrected so the lock is released after the rule is rejected in the case worker portal.

Layout Group tab alignment correctly shown in Microsoft Internet Explorer
Resolved in Pega Version 8.5.2
Even though the responsive breakpoint for a layout group was disabled, the tabs were getting changed to Menus in Microsoft Internet Explorer. This was traced to Tab-overflow being triggered in very small viewports when using Internet Explorer 11, and has been resolved by adding dom manipulations for all layout groups.
