Hazelcast will be used to determine node presence
Resolved in Pega Version 8.5.2
When calling logoff from the end user portal, sporadic PresenceStandardLifeCycleListener exceptions were seen during high load periods. This was traced to changes made in the Service Discovery behavior: when there is an issue with the node and heartbeats are missed, the node goes to Safe Mode. This caused the topology to change and trigger clearing off presence sessions, but the node still received service requests and this issue was seen. To resolve this, an updated has been made so the system will rely on the Hazelcast listener instead of service discovery to determine whether a node has left.

REST authentication settings use fully qualified name for resolution
Resolved in Pega Version 8.7.2
The application setting used in REST connectors for authentication was resolving to similarly-named rules instead of matching the exact name of the rule. This has been resolved by enhancing pzGetSettingID to use both parts of the fully qualified name (name and category) provided by the pzSettingsORA control when determining which setting from the report to return.

Data-Summary reports default will not use the rule resolved setting
Resolved in Pega Version 8.5.2

Agent tracing handling updated
Resolved in Pega Version 8.5.2
When attempting to trace agents the error "Unable to trace the agent" appeared on screen. Investigation showed that the data page used by the Tracer was not always available in a thread that was displaying the section, most commonly if the section was using deferred loading. This has been resolved by using a data page available in a thread that opens a Tracer's section.

Custom header character encoding for Subject added
Resolved in Pega Version 8.7.2
Case correspondence that contained a Subject with accent characters such as "Invitation à être" was being rejected by MailJet on the basis of encoding issues on the "Thread-Topic" when using custom headers. The error "BAD HEADER SECTION, Non-encoded non-ASCII data (and not UTF-8)" was generated. This was traced to the Send Email Smart Shape handling when using custom headers, and has been resolved by encoding the Subject before appending it to the Thread-topic header while adding custom headers.

Support added for allow list for LaxRedirectStrategy
Resolved in Pega Version 8.5.2
When using Connect REST with POST to access a third-party service deployed on multiple nodes, the load balancer sometimes replied 302 with Location header. The ability to allow the REST connector to automatically follow these redirects even in the case of POST messages is supported by Apache http client via LaxRedirectStrategy, but REST Connectors need both rule and engine enhancements to allow for this. To support this use, an allow list has been implemted for hostnames. This will allow the connector to be configured to follow the LaxRedirectStrategy only when the hostname of the redirect location is in the allow list. The default will continue to block the redirect.

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.

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.
