Hazelcast will be used to determine node presence
Resolved in Pega Version 8.4.4
When calling logoff from the end user portal, sporadic PresenceStandardLifeCycleListener exceptions were seen during high load periods. This was traced to changes made in the Service Discovery behavior: when there is an issue with the node and heartbeats are missed, the node goes to Safe Mode. This caused the topology to change and trigger clearing off presence sessions, but the node still received service requests and this issue was seen. To resolve this, an updated has been made so the system will rely on the Hazelcast listener instead of service discovery to determine whether a node has left.

Data-Summary reports default will not use the rule resolved setting

Methods updated to prevent rounding of JSON response decimals
Resolved in Pega Version 8.4.5
When using a REST connector for an outside service, precision numbers in the JSON response were being rounded or truncated when parsed for the DataSource page. For example, a JSON message with a value like 6045.900000000000000001 became rounded to 6045.9. This happened in both methods used for fast and non-fast processing, and has been resolved by treating the decimal value as a string and then creating a BigDecimal object out of it to avoid truncation in the fast processing scenario, and by adding mapper.enable(DeserializationFeature.USE_BIG_DECIMAL_FOR_FLOATS); for the non-fast processing scenario.

UseNoCacheHeaders default expiration set to "0"
Resolved in Pega Version 8.4.5
When the prconfig/HTTP/UseNoCacheHeaders/default was set true it used the value "Expires: Thu, 01 Dec 1994 16:00:00 GMT". This has been updated to the more commonly used setting "0".

Oracle temporary space explicitly freed after writing LOBs
Resolved in Pega Version 8.4.5
Oracle temporary space used to write the LOB was not freed up after writing records to Log-Service-File when using OJDBC8 or OJDBC10 versions and the table involved had inline BLOB storage such as small blob tables like Log-service-file (2-4kB blobs). This did not occur when using OJDBC7, but investigation with Oracle could not determine why the older version did not have this issue. This issue has been resolved by explicitly freeing the LOB space with a call to free() / freeTemporary() , a utility for LOB objects that was introduced in JDBC 4.

Custom header character encoding for Subject added
Resolved in Pega Version 8.4.4
Case correspondence that contained a Subject with accent characters such as "Invitation à être" was being rejected by MailJet on the basis of encoding issues on the "Thread-Topic" when using custom headers. The error "BAD HEADER SECTION, Non-encoded non-ASCII data (and not UTF-8)" was generated. This was traced to the Send Email Smart Shape handling when using custom headers, and has been resolved by encoding the Subject before appending it to the Thread-topic header while adding custom headers.

Monthly agents run correctly on non-English locales
Resolved in Pega Version 8.4.5
Nodes with non-English locales were not starting when using an Agent with a monthly execution pattern. This was due to incorrect handling of the user locale, and has been resolved.

MimeTypeHandler added for cloud downloads on mobile
Resolved in Pega Version 8.4.4
When using the Pega cloud storage repository (Application -> Integration -> Content Storage) with the Google Chrome browser on an android device, it was possible to upload attachments but re-downloading the attachments failed. Investigation showed that this was due to the content-type appearing as application/* so Google Chrome on mobile was not able to identify the file type. This was a missed use-case for returnFileForDownload(), and has been resolved by setting the system to use MimeTypeHandler for getting the content type.

Support added for allow list for LaxRedirectStrategy
Resolved in Pega Version 8.4.4
When using Connect REST with POST to access a third-party service deployed on multiple nodes, the load balancer sometimes replied 302 with Location header. The ability to allow the REST connector to automatically follow these redirects even in the case of POST messages is supported by Apache http client via LaxRedirectStrategy, but REST Connectors need both rule and engine enhancements to allow for this. To support this use, an allow list has been implemted for hostnames. This will allow the connector to be configured to follow the LaxRedirectStrategy only when the hostname of the redirect location is in the allow list. The default will continue to block the redirect.

ExpandStream called before Page-Merge-Into to ensure correct merge
Resolved in Pega Version 8.4.5
The Page-Merge-Into method was not merging the source page into the target page when the use case was run without tracer, but merged properly when run with tracer. This was traced to an intermittent issue with expanding properties, and has been resolved by calling expandStream on the source property if it is unknown prior to checking if the source and target properties are merge compatible.
