Added mail/telephone link to allowed CSP child frame
Resolved in Pega Version 8.4.5
After upgrade from v8.3 to v8.5, clicking on the mail / telephone link in the out of the box case participants gadget generated the Content Security Policy error "This content is blocked. Contact the site owner to fix the issue." Examination of the browser dev-tools console indicated the object refused to frame because it violated the Content Security Policy directive: "frame-src *". This behavior was specific to the Google Chrome browser, and has been resolved by adding code so the mailto: and tel: will be added to the frame-src when Data is selected under Child Frame-Source option. Unchecking the Data checkbox for Child Frame-Source on the policy landing page will remove these from allowed actions under CSP.

Skip restored for browser request CSRF token
Resolved in Pega Version 8.4.5
Many SECU0008 alerts were seen in the production logs. This was the result of a CSRF token check on requests without pyActivity or pyStream, and has been resolved by restoring a conditional skip of the check as those other browser requests do not contain a CSRF token.

Modified batch requestor handling to ensure cleanup
Resolved in Pega Version 8.6.4
A large buildup of batch requestors was seen, and restarting the node did not clear it. Investigation showed that in the case of one class reading a DSS value, a Pega requestor was being created when it was unable to retrieve any Pega context, and this requestor was not cleaned up afterwards. To resolve this, an update has been made to the way the requestor and Pega context is being created along with ensuring it will be cleaned up properly after use.

ADM Model management page updates
Resolved in Pega Version 8.6.4
When accessing the ADM model management landing page in an environment with a large number of nodes, an "UnresponsiveNodeException" error was thrown from the pylaststrategyresults activity by various nodes on different days. Investigation showed the ADM factory table was truncated, leading to inconsistent ADM data in the Last Responses Section. This has been resolved, and the ADM model management page has been made more resilient to node failures.

Natural Language Processing (NLP) topic categorization working consistently for German
Resolved in Pega Version 8.6.4
A few German words were not recognized by the Natural Language Processing (NLP) topic categorization if they were given in capital letters. This was traced to upper case keywords being lowercased during model creation time, but not during prediction time. To resolve this, all words will be lower-cased before the model analyzes the text.

Delayed Learning works correctly with Volume Constraints
Resolved in Pega Version 8.6.4
When running an outbound campaign using NBA Designers predictions and delayed learning in conjunction with volume constraints, the adaptive models ended up with incorrect feedback if the prediction had an Alternative label configured with a defined waiting window. This has been resolved with the addition of a new flag 'isVolumeConstraintEnabled' during dataflow creation which will check for volume constraint, and a filter in HandleResponses for that flag.
