Refinements made to MarkerNode memory use
Resolved in Pega Version 8.4.2
Significant memory usage can be observed when data join in strategies are missing the join conditions. E.g., when the primary source in the strategy can have up to 300 or even more propositions, the join without the join condition would perform a cartesian product with possibly up to 400 or even more records returned. This may cause performance degradation. To guard against this, an update has been made that seeks to prevent repetitive markers being accumulated under a MarkerNode while trying not to rely on any implementation of equality and hashCode for individual marker implementations.

Unneeded MBean startup warning removed
Resolved in Pega Version 8.4.2
After upgrade, Catalina logs indicated the error "WARN com.pega.dsm.dnode.api.prpc.service.monitoring.MBeanDSMService - Service DataFlow doesn't implement Monitoring operation". This was due to a flaw in the way the data flow DSM service was initialized in client mode. The exception itself was not a problem and did not impact functionality, but the client initialization has been modified to remove the warning.

Declaratives disabled during startup
Resolved in Pega Version 8.4.2
Declaratives firing before the engine is fully up can lead to null pointer errors. In order to avoid this condition, declaratives will be disabled during startup so that unnecessary operations can be avoided and system can be started faster.

Pulse mentions correctly tagged in Google Chrome
Resolved in Pega Version 8.4.2
Pulse mentions of spaces or users were not getting tagged correctly. This issue was due to recent changes in the way touch events are handled in Google Chrome: the latest upgrade removed the ontouchstart property in the window, causing the isTouchable capability identification method to fail. As part of the work done to resolve this, it was discovered that the initAutocomplete function in the pzJquerymentionsInput .js was failing to delegate the mousedown event. This has been corrected by delegating touchstart and mousedown while initializing if screen isTouchable.

Placeholder text added for question dropdown sourced by a datapage
Resolved in Pega Version 8.4.2
In a flow action with question pages where each question page was configured with a set of question rules, one question which displayed a country list in a dropdown sourced from a datapage always displayed the first value by default in the dropdown instead of place holder text (like Select..). In addition, the default selection value of the dropdown was not saving to the clipboard on submission of the flow action, causing it to appear in the UI like the first value had been selected even though nothing was saved on the clipboard. These issues have been resolved by adding place holder text in pzSetQuestionStreamSimpleDynamicSelect for a dropdown with a datapage source

Landing page refresh modified to avoid frequent reloads
Resolved in Pega Version 8.4.2
Approximately every two weeks, clients were able to login but it was not possible to work as the landing page refreshed constantly until all of the nodes were rebooted and the issue was cleared. Investigation indicated the frequent reloads were related to the cacheing of the operator details, and this has been resolved by updating the datapage reload strategy based on 'when' so frequent reloads will be avoided.

Spaces member count method updated
Resolved in Pega Version 8.4.2
When a space contained more than 50 members, it always displayed the count as 50 even though the Spaces section showed the correct count. This was due to a pagination setting that had a maximum of 50 records set, and has been resolved by using the GroupMemberCount DP instead of AllMembers to retrieve an accurate count.

Resolved mobile app java.lang.OutOfMemoryError
Resolved in Pega Version 8.4.2
After working with the mobile app for a period, logging in failed and the app crashed with java.lang.OutOfMemoryError exceptions. This was traced to each sync adding a new version of allow-list datapages to the client store which were not cleared, and has been resolved.

Accessibility improved for Pega Survey Question pages
Resolved in Pega Version 8.4.2
Question Pages in Pega Survey lacked accessibility. This was traced to aria-label not being generated for Radio buttons and Drop-downs, and "title" not being generated for other controls used in Question and Question Pages. This has been resolved.

Improved usability for long Pulse notes
Resolved in Pega Version 8.4.2
After a Pulse message exceeded 32 lines, the window scrolled to the top of the screen after each keypress, obscuring the typing. This was traced to the CSS on the textarea span, and has been resolved by modifying create-new-pulse to display:inline-flex; in pzpega_social CSS.
