New email template added to include full message history
Resolved in Pega Version 8.4.4
Whenever a reply was sent from the email triage case, the outbound email sent only the actual reply along with the original email and latest reply only, skipping all remaining replies from email. For example, if there were 5 replies from case, replying 5th time generated an outbound email that contained only 5th reply (actual / current), original reply (which created the service case) and the latest reply (reply 4 in this case) and skipped reply 1 and reply 2. To resolve this, a new Outlook-style template has been added for use in replies that will include all of the previous exchanges.

Updated handling for unexpected character set in non-UTF-8 email
Resolved in Pega Version 8.4.4
After upgrade, the listener properly created a case from an email, but the space character was being replaced by ? in the inbound emails. Investigation showed the messages did not appear properly in the UI if the email was sent using any encoding other than Unicode (UTF-8) and it had a special character set. To resolve this, the system will remove the attachment type which includes the charset.

Email Triage properly maps attachments to case
Resolved in Pega Version 8.4.4
Attachments from emails coming in via the Email channel were not being attached as expected to both the Email Triage case and the case generated from that. Instead, attachments were only being added to the triage case. This was traced to the pyAttachments property not being properly updated for attachment to the generated case, and has been resolved.

Double quotes escaped in entity mapping
Resolved in Pega Version 8.4.4
A usecase where the BOTS created the triage cases from the emails and pushed it to the Workgroup had an intermittent problem where the screen would freeze and no actions could be performed. perform any action on the same. Investigation showed this occurred when the entity text contained double quotes which is caused JSON to break on the client side. This generated an exception during rendering, and other onload scripts failed on load and blocked the entire thread. To resolve this, the system will now avoid the JSON break by escaping double quotes in entity mapping.

Updated SLA table clearance
Resolved in Pega Version 8.4.4
After cases were resolved, SLA entries were not getting cleared from the SLA table. This caused the SLA table to have a huge number of Overall SLA and PendFlow details present for cases that were resolved or moved to the next state, which impacted case processing via SLA Agent. This was traced to SLA queue-items not being removed by delete-deferred as expected, and has been resolved by invalidating the deferred operations and scheduling item removal.

Documentation updated for binary REST response
Resolved in Pega Version 8.4.4
The online help documentation has been updated to clarify the instructions for REST endpoints that return binary data. In some cases, the data is returned in a MIME multipart structure. It can also be returned as the response body. In the latter case, mapping the message body to a java object property will cause the binary data to be mapped as a java byte array value. Mapping the message body to a single value text property will cause the binary data to be mapped as a Base64 encoded text value.

Oracle performance improvement
Resolved in Pega Version 8.4.4
Poor performance was seen when importing a RAP with schemas using Oracle. To resolve this, an update has been made which will set the Oracle tuning parameter at the session level by altering the setting "_OPTIMIZER_PUSH_PRED_COST_BASED"=false before the SMA query involving all_constraints. The setting will be returned to true after the execution of the SMA query. This is controlled through the prconfig setting '"database/performance/smaqueryperformanceenabled" which defaults to true so the setting and unsetting of the Oracle parameter is automatic.

Improved resolved rules cache
Resolved in Pega Version 8.4.4
When Rule resolution iterated over a candidate list to fetch a candidate, performance issues were seen on very large sites. To resolve this, an enhancement has been added that will cache the resolved virtual table entries to optimize performance in high demand use cases like DSM.

Locking and classmap improvements
Resolved in Pega Version 8.4.4
Threads were getting stuck inside classMap and tableInformationMap, causing nodes to go down. This was traced to issues with classmap performance and locking, and has been resolved by replacing the lock library with a newer version and refactoring the tableInformationMapImpl class to use a concurrent hashmap instead.

Updated Tracer for cluster events
Resolved in Pega Version 8.4.4
When running the tracer from the Admin Studio Listener management landing page, Tracer was always fetching data from one node only even though events were generated on another node. This was due to the specific node where the Listener was running being passed to the concern activity while launching the tracer; the Tracer Client node did not have data to check if the event was being populated on another node, and the result was to always fetch data from one node only even though events were generated on another node. To resolve this, the web node ID where the event is running will be passed.
