Handling updated for queue processor locks
Resolved in Pega Version 8.5.6
The Final activity mentioned in the processing epilog of the Service File rule was not being consistently called from File Listener, causing some of the cases to become stuck and not continue to the next stage. Investigation showed that if the lock was held by the queue processor requestor, the system was unable to obtain the lock but still proceeded to update the LogServiceFile page and persist it. This resulted in overwriting changes made on the LogServiceFile page by the requestor, resetting the completed-batches-count set back to 0. To resolve this, RuleServiceFile -> updateLSFBatchCounts() will call the overloaded lockAndLoad() method in LogServiceFile that accepts a parameter called lockAttempts. This will attempt to obtain a lock for a given number of times before throwing an exception.

Zip compression added for tracer XML
Resolved in Pega Version 8.5.6
After upgrading from Pega 7 to Pega 8, attempting to save and download a trace session would run for a time before pausing and displaying the message "Operation failed. Network error". Investigation showed the tracer was generating a very large XML file which was consuming the heap and causing the issue. To resolve this, an update has been made that will reduce memory usage by using GZip compression on the file. The new behavior will be to always zip tracer XML by default.

Attached zip file has correct extension
Resolved in Pega Version 8.5.6
When using a custom function with the SendSimpleEmail activity, an attached .zip file was corrupted on receipt. The issue was not present with other mime types (ex. images, docs, pdf). Investigation traced this to the extension for the zip file being incorrectly set as xzip or multipart, and this has been resolved by adding a condition to set the extension correctly.

API added to handle digital signing from proxy layer
Resolved in Pega Version 8.5.6
When an email account was configured with a valid email account and keystore for message signing, it was possible to send emails with valid digital signatures. When the same email was used in case type email instantiation, no digital signatures were included in it. This was due to keyStoreInstance properties being read from the email account top level page when they need to be retrieved from pyEmbedSenderProtocol page when using SMTP. This has been resolved by adding an API to handle the signing logic from the JavaEmailClientProxy class.

French added to Locale List Separator
Resolved in Pega Version 8.5.6
Exporting data to Excel in CSV format resulted in text with French accent characters such as "Décision pour une nouvelle demande de règlement" to appear as random characters, and columns were not being split. This has been resolved by adding a record for the French locale in the pzGetLocaleListSeparator decision table rule.
