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.

Breadcrumb functionality disabled for Process Modeler pending further development
Resolved in Pega Version 7.1.8
Some complex installations experienced OOM events and crashes when opening flows in Process Modeler that contained nested levels of nested sub flows. The root cause of this problem was code that allowed excess data to be opened into the clipboard for every sub flow that could potentially be run as a result of running the top level flow. To prevent this problem, breadcrumbs functionality has been disabled at this time. The canvas viewer is being rewritten for ML9 together with a new implementation of multi-level process navigation in order to resolve this issue.

Appearance order retained for multiple swimlanes
Resolved in Pega Version 7.1.8
After putting multiple swimlanes in a flow, the order of their appearance was returning to the original state after saving it. This was caused by the rendering being performed in the order the server store/sent the swimlane data. To ensure proper behavior, the swimlanes are now reordered based on the swimlane layout (horizontal, vertical) and their coordinates before being rendered.

Multiple annotations now allowed for swimlane objects
Resolved in Pega Version 7.1.8
When two annotations were used with swimlanes, the description in the annotation is unexpectedly changed or the annotation itself disappeared due to an ID conflict. There was a workaround of adding the shapes using the right click, but the annotation shape is now correctly added to the work flow using the proper unique ID.

Dropped rule added to DSM rules for SR properties
Resolved in Pega Version 7.1.8
A set of rules was inserted into the UI of Proposition LP and Strategy rules in DSM (Designer Studio) for use in retrieving a list of SR properties. This set was inadvertently missing the rule 'Activity Embed-Decision-SPContainer . pyRefreshSPList', and this has been added.

Shutdown issue with Tomcat resolved
Resolved in Pega Version 7.1.8
During shutdown, errors were reported on the App Server window. Shutdown did not complete and the App Server Window remained open. This was due to the "Shutdown" button/feature not properly terminating Tomcat. There was a workaround to manually close the Tomcat window, but the DNodeServiceListener has been modified to release all of the threads properly.
