Tab panel read meaningfully by screen readers
Resolved in Pega Version 8.3.5
When the tabPanel received focus with accessibility, the entire tab content was read instead of the W3 standard of only reading "Edit ". This has been resolved by ensuring the Tabpanel has the proper aria-labelledby.

Tab will exit portal side menu
Resolved in Pega Version 8.3.5
It is expected that the Tab key will take users out of the portal menu and to the next focusable element, but on the side navigation menu both tab and arrow keys moved to the next menu item. This caused users to have to navigate the entire menu. The correct behavior was seen for the Navigation rule when called from an Action (for example on the button). This was traced to the system using tabindex as "0" for every element in the menu, and the tabs code has been updated to exit out of the menu bar when pressed.

Third party cookies reminder added for Mashup in incognito browsers
Resolved in Pega Version 8.3.5
When working in incognito/private browser windows, attempting to use Mashup displayed a message indicating login credentials were not recognized ("Unknown password and/or username"). This was due to recent changes originating with the browsers regarding blocking third-party cookies which are necessary for Mashup to run. For informational purposes, a new API has been added which will check for the PegaRules cookie; if the cookie is not present, the message "Third party cookies must be enabled for Mashup to function." will be displayed. This message may be customized by configuring the setting "pega.web.config.xCookiesDisabled" with the required message.

Try catch added for templated refresh when
Resolved in Pega Version 8.3.5
After configuring a refresh when condition on a dynamic layout triggered by changes on D_worklist.pxResults, a component stack mismatch error was generated if client side UI template is enabled. Without templatization it worked as expected. This has been resolved by adding a try catch block to DynamicLayoutGenerator.java.

Update Handler will not run during migration
Resolved in Pega Version 8.4.1
Rolling restart of DataFlow, ADM ,VBD, and Util Tiers failed with a PENDING_JOINING error after an in-place upgrade. This was traced to the logic for the update timing: when nodes start after an upgrade from 7.x to 8.x they will migrate data flow runs. Migration happens on only one node, and while it's in progress the other nodes will wait until migration finishes before they come up. At this point the state of the data flow services will be 'PENDING JOINING'. The issue is that while migrating runs, the Data Flow Update Handler was triggered to validate whether there were nodes available on the service the run belongs to. This call can cause the corresponding data flow service to be initialized, but the call will be blocked since all services wait for the migration to end. This resulted in a deadlock which prevented all nodes from coming up successfully. To resolve this, the process has been updated to skip the update handler during migration to avoid triggering the initialization of client services that are waiting on the migration lock.

DDS service will not run Hazelcast check if external Cassandra is configured
Resolved in Pega Version 8.4.1
Services were not responding, and thread dumps seen in the logs indicated that a large number of threads were waiting for one to come back from getting the cluster state for a DSM process. Investigation showed that the threads were waiting for a Hazelcast response about the cluster state. However, since a Hazelcast call is not needed when Pega is configured with external Cassandra, the DDS Service code has been changed to not to check for candidate nodes if configured with external Cassandra cluster.

Corrected calculating propensities
Resolved in Pega Version 8.4.1
Several PMML models designed to compare the outcomes to a control dataset experienced an issue where the probability scores in Pega did not match the original control dataset. The PMML model was also tested using KNIME; those results matched Pega but not the original control dataset. Investigation showed that the JPMML evaluator contained outdated code, and the incorrect calculations have been resolved.

DataSet preview will use date instead of datetime
Resolved in Pega Version 8.4.1
While using a DataSet preview functionality, the date appeared as reduced by one day. This has been resolved by parsing date as 'date' instead of 'datetime' to avoid issues with timezone interactions.

Added tokenizer for KeyWord-Based Topic Detection phrases
Resolved in Pega Version 8.4.1
KeyWord-Based Topic Detection was not Working for "Enrollment/Re-Enrollment" as a word, for example a categorization model with the text 'This is an email related to Enrollment/Re-Enrollment'. To facilitate this use, a tokenizer has been added to break 'should',' must', and 'and' words into components for a taxonomy match.
