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.

Updated visibility condition expression handling for decimal values
Resolved in Pega Version 8.5.2
After upgrade, any visibility condition expression failed to evaluate decimal values that used precision. When 0 (zero) was entered as a value in the input field, a button that was configured to show was visible as expected. When the value was entered as 0.0, the input failed and the button did not show. The problem did not happen "Run visibility condition on client" was enabled. Investigation showed this was an issue with how the When expression was evaluated and calculated within JspWhenEvaluate, and has been resolved.

Check added for HTML and linefeed combined in email
Resolved in Pega Version 8.5.3
In the Interaction right hand pane Email triage widget, additional line breaks were seen when displaying email message data that contained table tags. This was a missed use case for email which contains both HTML and '\n', which resulted in the system replacing '\n' with </br>. This has been resolved by adding a check whether the content has HTML tags which will avoid the replacement.

Updated email triage case creation to avoid unique key issue
Resolved in Pega Version 8.5.3
After upgrade, when the email listener queued the case and an agent picked up the queued item to create an Email Triage Case and then the interaction case, trying to commit the case failed with a Unique Key violation. Investigation traced this to the system trying to insert the record into the PC_WORK_TRIAGE table twice due to a timing issue in the workobject commit. This has been resolved.

EnableRedirects property added for REST connections
Resolved in Pega Version 8.5.3
When implementing a connector with the header �Location� which contains a redirect URI, a 303 response code was expected. Instead, a 400 or 404 error was generated. It was not possible for developers to process the code per their logic in Activity as Connect REST processed 303 responses automatically - i.e. there was no intercept points to implement the suggested approach. To resolve this, the new property "Rule-Connect-REST.pyEnableRedirects" has been added along with a checkbox for the property in "Rule-Connect-REST.pyService" in "Connection" section. Logic has been added in RESTConnector.java to take value of this property and set it on the HTTPClient being used, and a method has been added to HTTPClient interface and ComponentsHTTPClient to use the new value being passed. The default behavior is the same for the REST Connector, but a client can uncheck a checkbox on the REST Connector ruleform to stop the HTTP client from automatically following any compatible 3xx responses.

Added Database query optimization and cache invalidation logging
Resolved in Pega Version 8.5.3
Web nodes were going down during deployment due to failed health checks. This was traced to queries firing even when there was no rule change, and was due to unnecessary cache invalidations. An update has been made which will optimize and analyze declarative database queries and capture diagnostic details on any invalidation of the declarative reference information cache.

Performance improvements for Attachment Migration Utility
Resolved in Pega Version 8.5.3
The Attachment Migration Utility was showing a zero count for attachments in the Pega Database. This was traced to the underlying report definition that retrieves data for the Attachment Migration Utility timing out, and has been resolved by updating the activities to improve performance for applications having a large number of attachments without customization.

Logging for MultiNodeSynchronize lock attempts changed from error to warn
Resolved in Pega Version 8.5.3
The File Listener was logging numerous errors stating "Unable to establish MultiNodeSynchronize lock while trying to determine if listener is enabled for this node". Handling has been previously established for error cases when the Listener is unable to establish a MultiNodeSynchronize lock, but this condition continued to be logged as an error even though it was not related to any failures in functionality. To resolve the logging issue, the logger level has been changed from ERROR to WARN.

MimeTypeHandler added for cloud downloads on mobile
Resolved in Pega Version 8.5.3
When using the Pega cloud storage repository (Application -> Integration -> Content Storage) with the Google Chrome browser on an android device, it was possible to upload attachments but re-downloading the attachments failed. Investigation showed that this was due to the content-type appearing as application/* so Google Chrome on mobile was not able to identify the file type. This was a missed use-case for returnFileForDownload(), and has been resolved by setting the system to use MimeTypeHandler for getting the content type.

Resolved in Pega Version 8.5.3
Diagnostic logging has been added to REDUX query references which will capture information about exceptions that cause the system to fallback to generating legacy references.
