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.

Web Tier busy threads released on timeout
Resolved in Pega Version 8.7
Tomcat Web Tier Busy Threads were not being correctly released, causing stability and performance problems that included health check pings not receiving a thread to service the request so the node was marked as bad, users were quiesced, and the node replaced. Investigation showed the 'put' on the blocking queue did not time out when the queue was full and waited indefinitely, keeping the thread blocked. To resolve this, the system will use 'offer' on the blocking queue instead of 'put' to force thread release on timeout. In addition, debug logs have been added to understand when the offer (or Put) does not succeed and the state of the queue that is causing this issue; the debug logs for class com.pega.pegarules.session.internal.serverpush.RoboticAutomationImpl should be enabled only if the thread busy issue is observed and for limited time window while actively debugging.

After upgrade, the DSS 'dsm/services/stream/pyTopicPartitionsCount' used to limit the number of partitions was no longer working and instead used the default value of 20. This has been corrected and made backwards compatible.

Check added to ensure read locks are released
Resolved in Pega Version 8.7
Read locks were not being properly released if a thread was holding a read lock and the system encountered an issue such as an out of memory condition. To resolve this, an update has been made to DeclarativePageDefinitionCacheImpl which will check whether a thread holds any read lock before trying to acquire a write lock, and if so release all the read locks held by that thread.
