Handling updated for redirect URI construction
Resolved in Pega Version 8.4.2
The redirect URI for an ODIC authorization request to IDP from Pega was truncated, resulting in an incorrect redirect URI. This was traced to the App alias feature was introduced in 8.4 which appends /app/ to the context URL. While constructing OpenID authorization request, the redirect URI was constructed from current login context. In the process of removing the app alias from the URL, a conflict was seen when the server name contained the word "app" in it. To resolve this, the app alias handling has been updated.

Updated jar supporting SAML login to work with JRE11
Resolved in Pega Version 8.4.2
SO authentication was failing with the exception "Caused by: java.lang.NoClassDefFoundError: Could not initialize class org.apache.commons.ssl.TrustMaterial". That class was packaged with Pega via the not-yet-commons-ssl.jar which is no longer being developed and only works with JRE8. This has been resolved by updating the package to the new not-going-to-be-commons-ssl.jar which has been evaluated for all supported JRE versions.

10 minute cap added to lockout time interval for failed logins
Resolved in Pega Version 8.4.2
After a certain number of failed attempts, there is a process that locks out the operator for a time interval. When the interval has expired and the operator is able to try again, the next "lockout" uses a time interval double the prior size. Previously, this was able to grow without any restriction. In order to improve effective requestor management, an upper limit has been added for maximum lockout period. The default has been set at 10 minutes or 600 seconds, but this may be configured using the DSS : authPolicy/delay/maxDelay in the Ruleset: Pega-Engine. The value is set in seconds: if the value specified in the DSS is greater than 600 seconds, then the maximum lockout period will fall back to 600 seconds (10 minutes).

CDK key loading modified for better database compatibility
Resolved in Pega Version 8.4.2
Users were unable to log on to the system and received the error "There has been an issue; please consult your system administrator." Investigation showed the log errors stating "(dataencryption.DataKeyProvider) ERROR localhost - Could not get CDK from systemKeyManagementCache - System CDK is null". This was an issue specific to the MS SQL Server database when there were 6 or more CDKs in the database: CDK keys are loaded from database into Cache using an SQL statement which had the ORDER clause. By default, the ORDER clause treats NULL values differently on different databases, and this caused MS SQL databases to not load a necessary CDK key. To resolve this, the SQL query has been modified so the result will be the same for all supported daatbases (Oracle, Postgres & MS SQL Server).

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.
