Fixed flow line distortion in Process Modeler
Resolved in Pega Version 7.1.9
When clicking through to a subprocess from a parent flow (by clicking the + sign in the blue subprocess shape), flow lines in the subprocess were shown in a distorted fashion. When opening the same flow in a separate tab (by right clicking the blue subprocess shape and selecting Open Flow) the flow lines were correctly painted. This was an issue caused by the different renderings of the flow depending on whether there was a click through to it (with the + on the parent flow?s subprocess shape), or the subflow was opened in a separate tab (with open Flow). After the Process Modeler saved and checked-in the flow, the connector lines were re-drawn in ways that were non-intuitive and hard to interpret due to the edge routing in PM being calculated off incorrect input data that was taking into account shapes that were not represented on the screen. To fix this, the system now ensures the edges are routed without taking into account any shapes not represented on the canvas.

Fixed scrumboard intermittent failure
Resolved in Pega Version 7.1.9
After upgrading, it was seen that the scrumboard would intermittently fail to load, partially displaying and then hanging if the columns did not fit within the window boundaries due to the number of elements. This was traced to an error in the functionality that resizes parts of the scrumboard, and has been fixed.

Enhancement added for node heartbeat recovery process
Resolved in Pega Version 8.3.5
Nodes were not showing up in the admin portal even though they were up and running and could be seen in the pr_sys_statusnodes table. The exception "An exception was encountered while invoking the cluster membership listener callback" was seen. All nodes became visible again after multiple restarts. The root cause was traced back to a temporary database connectivity problem. The database itself was fine according to database monitoring reports, but a network problem, a slow database query, or another issue prevented Pega from establishing a connection for more than a minute. An enhancement has been made to resolve this: if a node becomes unhealthy due to the service registry missing due to a failed heartbeat, the heartbeat will try to recover after 60 seconds and keep trying every 30 seconds until it succeeds.

Resolved Cassandra query read/write latency
Resolved in Pega Version 8.3.5
Read/write latency was seen when certain Cassandra queries were triggered by the system. This was traced to an unusual case where a flush was not done for an exceptionally long time period, and has been resolved.

Corrected method IF use with shortcut function
Resolved in Pega Version 8.2.5
After upgrade, method IF was not working as expected when used in an expression like "@if(.totalorders_120days>0,(.remakeorders_120days/.totalorders_120days)<0.3,false)". This was caused by a missed use case for the combination of an exception-generating function in combination with a shortcut function (i.e. ternary, and, or), and has been resolved.

Fallover stategy added to chat routing to keep event processor running
Resolved in Pega Version 8.2.5
Chats were becoming stuck in the queue and end users were not able to connect with the customer service representative. An excessive number of queued items were observed in a Queue Processor named "EventProcessor". This was traced to the setting "Browse from the offset" having been removed because of a retention policy. This resulted in "Browse from the end of the stream" being used instead even though browse should start from the earliest known offset. To resolve this, Stream Producer will be cached based on topic, and Stream consumer will fall over to an earliest strategy in case the requested offset isn't found so the event queue will be handled in a timely manner.

Support added for auto restart of system paused nodes
Resolved in Pega Version 8.2.5
After the system paused a run, nodes had to be manually restarted by hand. Investigation showed that a node had fallen from the Hazelcast cluster due to an instability and that there was no support for an auto-restart under this condition. This has been resolved by adding a pulse task to resume runs stuck in system pause.
