ExposeCols supports running serially
Resolved in Pega Version 8.1.8
MSSQL can be prone to deadlocking, causing potential issues with ExposeCols (column population and index generation) which defaulted to multi-threaded. To resolve this, the system has been updated to allow configuration of ExposeCols to run serially: the properties expose.commitRate, expose.numOfThreads, and expose.batchsize in setupDatabase.xml ExposeCols executions, which were previously only available to prpcUtils, will be honored.

Browser cache disabled to ensure fresh RAP file retrieval
Resolved in Pega Version 8.1.8
When using RAP download, reusing the same filename as a previous download caused the older file to be retrieved and not the newer version under that name. This was caused by RAP using the browser cache and downloading the same folder from service export directory. To resolve this, validation has been inserted to disable using the browser cache for the HTTP response.

Access Control Policy updated to handle NotEqual with valuelist
Resolved in Pega Version 8.1.8
When editing the Access Control Policy Condition rule in Designer Studio and setting condition to 'is not equal', comparing it to a list generated the error "function not found". The same configuration worked as expected for the 'is equal' condition. This has been resolved by updating policycondition to handle a not equal scenario combined with a valueList property.

Updated key handling for ProcessJWT
Resolved in Pega Version 8.1.8
After configuring an authentication service which used the ProcessJWT activity to validate the token received, the error "Unable to process the Json Web Token " was seen. Analysis showed the error was caused by a duplicate Key Id in JWK Endpoint Response: the system removed keys after processing, and in the case of duplicate keys the system was throwing null pointer exception because the key had already been removed. To resolve this, the system has been updated to not remove the keys from the map as part of this process.

Cleanup added for staging directory
Resolved in Pega Version 8.1.8
Temporary files from imports and exports (from DevOps) were filling up the staging area disk space because there was no automatic process for cleaning up these local files. This has been resolved by adding an enhancement that will clear the directory on Engine Startup and any time ParUtils.setStagingDirectory gets called to initialize the staging directory.

SameSite cookie setting added for Mashup support in Google Chrome v80+
Resolved in Pega Version 8.1.8
The Google Chrome browser version 80 and above now treats SameSite with a blank value as "Lax" by default, causing mashup scenarios to break. In order to compensate for this change, support has been added for setting SameSite=None in Cookie Settings; this value automatically includes the “secure” cookie flag, which enforces HTTPS for the Pega server and mashup. For mashups to work, SameSite should be set as None. Create a Dynamic system setting in the Pega-Engine RuleSet with the name “security/csrf/samesitecookieattributevalue” and the value "None" and restart the server. (The SameSite value "None" works only in secure HTTPS connections.) Note: The SameSite cookie may be set to None/Lax/Strict, based on the requirement. For cookie requirements other than mashup, it should be set as either Strict or Lax, depending upon your application.

Run Ruleset Cleanup defaults to true
Resolved in Pega Version 8.2.6
After upgrade, the rule categories and rules were not showing correctly in the App view of the Dev Portal. Many warning messages were also logged related to the Decisioning DM Sample application. This was traced to the rules cleanup script not running properly. While there was a workaround of applying the ruleset cleanup scripts manually after removing the queries that reference the pr_engineclasses table, the cleanup will now be set to run by default (run.ruleset.cleanup=true). In addition, the logic to determine which RuleSets to include has been simplified and most of the pr4_rule_vw deletions have been combined.

Data pages explicitly cleared after QP use
Resolved in Pega Version 8.2.6
The Util Node was showing as Offline in the Search Landing Page, and when Jobs were submitted for execution from other Nodes the message "Detected active run with unreachable nodes" was logged. The util node, configured as a backgroundprocessing node, was running QPs; the queue size for custom QPs is 500 messages /queue items per minute, but investigation showed the requestor level and thread level data pages corresponding to the QP activities were not being cleared after use. This led to high heap memory issues that made the node unreachable, and has been resolved by adding code to explicitly remove the data pages when processing has finished.

Hazelcast upgraded to resolve node startup issue
Resolved in Pega Version 8.2.6
Post data upgrade, the ADM tier failed to start and the error "java.lang.IllegalStateException: Node failed to start!" appeared. This was traced to a dormant bug in Hazelcast 3.11 that caused starting nodes to fail when the Hazelcast master node was shutting down, which was exposed by recent Pega changes made to enable parallel restarts of nodes in Cloud environments. Hazelcast delivered a fix for the parallel restart problem and the hotfixed jar has been merged into the platform. In addition, previous logic for loading Admin Studio waited 30 seconds before timing out when fetching information for each node. This caused issues with large clusters and Admin Studio not loading. The logic has been updated in the Admin Studio UI to load the page despite delays/issues waiting for nodes to respond to the gathering of cluster data, and the algorithm to detect remote-call timeout has been updated and is applicable to batch operation.
