Web Tier busy threads released on timeout
Resolved in Pega Version 8.6.1
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.

Resolved Push Node Daily Information exception
Resolved in Pega Version 8.6.1
The "Push Nodes Info Daily" agent was generating an exception on each of the nodes. This has been resolved by enhancing the PegaAESRemote code to handle the exception and get the node info locally, then push it to the console when it is not able to get it via the cluster management API.

Certificate match will use Subject Distinguished Name
Resolved in Pega Version 8.6.1
Signature verification was failing due to the system not finding the matching root certificate for the chain. The root certificate was in the trust store, but the system found a different certificate first and that other certificate (an intermediate certificate) was not considered a valid certificate for validating the whole certificate chain. This was traced to filtering on the Issuer Distinguished Name (DN) instead of the Subject DN and was due to intermediate certificates potentially having the same Issuer as a root certificate (e.g. if that root certificate was used to create the intermediate certificate). To resolve this, an update has been made to check the Subject DN instead of Issuer DN.

Instance count logic updated
Resolved in Pega Version 8.6.1
A performance issue was seen during update that resembled an upgrade hang. This was caused by a combination of incorrect logic in DDLGenerator.getInstanceCountForClass() around counting instances of 'core' classes and all of the site history-data- tables being mapped to the same table that had 1.4+ billion rows. This behavior has been addressed with more correct query logic while performing instance counts. In addition, instance count will be supressed during command line invocations (prpcUtils, platform upgrade).

Documentation updated to clarify displaying property values for Declare Expressions
Resolved in Pega Version 8.7
The documentation regarding Declare Expressions rules has been updated to clarify that declare expressions do not support displaying values of target properties in the user interface if the target property is an embedded property and if the calculation engages forward chaining. Declare expressions always display property values if the calculation uses backward chaining. During forward chaining, the system might render the UI before populating the clipboard, and the properties are not visible in the UI. To show updated values, define refresh conditions in the UI to get new values from the server when the values change.

Documentation updated for accents and special characters used in search
Resolved in Pega Version 8.7
The "Pega search API" article has been updated to reflect that the search functionality in Pega Platform does not match accented words with unaccented. For example, searching for santé and sante will retrieve different results. In addition, Domain Specific Language (DSL) includes special characters for use when searching, for example '-', '_', '!', '@'. However, the system retrieves various results depending on the way the special characters are used in the search query. If the query contains special characters that are not escaped, the system may retrieve incorrect results. For example, not escaping the slash mark in the 25/02 query may cause the system to ignore the special character.
