Published Release Notes

Data Flow service in the Pega 7 Platform

The Data Flow service configuration on the Services landing page now provides a single point of entry for enabling running data flows in batch and real-time modes. To configure the Data Flow service, you must add Decision data nodes on which to run data flows and specify the number of Pega 7 Platform threads that are assigned to process the data flow runs. Additionally, as part of the Data Flow service, you can view the number of active data flows on each node.

For more information, see Services landing page.

External keystore support in Pega Platform

Pega^® Platform now provides the ability to source certificates and encryption keys from external keystores. You use the Keystore rule to specify alternatives to the platform's database to source certificates and keys. You can choose to use a data page, a URL, or an external file in one of the following standard formats: JKS, JWK, PKCS12, KEYTAB, or KEY. Keystore information is stored in cache memory only. It is not stored on the clipboard nor is it directly accessible to the application logic.

For more information, see Creating a Keystore data instance.

Send event notifications in Pega Platform

You can configure applications to notify users of case changes or other significant events that occur in an application. Use notifications to engage application users by providing key updates that might be of interest to them.

You can deliver notifications over the default web gadget and email channels or use a custom channel that you created. You can configure multiple web gadgets to display different kinds of notifications. The email channel supports notification frequency of instant, daily, or weekly.

Application users can set their own notification preferences in the run-time portals or override the set preferences for a specific case type instance.

For more information, see Sending event notifications and Management of user notification preferences.

Pega Platform ends support for Java 7

Oracle has ended support for Java 7 and is no longer issuing security patches for Java 7. Therefore, starting with Pega 7.4, Pega® Platform no longer supports Java 7. For more information about supported platforms, see the Platform Support Guide. For more information about Oracle support for Java 7, see the Oracle documentation.

Upgrading to Hazelcast 4.x requires downtime during upgrades to Pega Infinity 8.6

Upgrade impact statement

On-premises upgrades of Pega Infinity release 8.4.2 and later to version 8.5.1 or later on Tomcat and PostgreSQL are completed with near-zero downtime. However, upgrading to Hazelcast 4.x requires that you shut down and restart your application server.

What is required to update the application to be compatible with this change?

Hazelcast 3.x is enabled by default. For near-zero downtime upgrades, you do not need to perform any action.

For instructions about upgrading to Hazelcast 4.x, see one of the following topics:

• For near-zero downtime upgrades from Pega Infinity release 8.4.2 or later on Tomcat and PostgreSQL, see "Optional: upgrading to Pega Platform version 8.6: Upgrading to Hazelcast 4.x" in Near-zero downtime Upgrade Guide for Pega Platform version 8.4.2 and later for Tomcat and PostgreSQL.
• For all other upgrades, see "Optional: upgrading to Hazelcast 4.x" in the appropriate upgrade guide.

Cassandra 3.11.3 support for Pega Platform

Increase your system's reliability and reduce its memory footprint by upgrading the internal Cassandra database to version 3.11.3.

For on-premises Pega Platform™ users, after you upgrade to Pega 8.3, it is recommended that you manually upgrade to Cassandra 3.11.3. You can upgrade to Cassandra 3.11.3 on all operating systems except IBM AIX. If you do not want to upgrade to Cassandra 3.11.3, you can continue to use Cassandra 2.1.20, which is still supported.

For Pega Cloud Services 2.13 and later versions, Cassandra automatically upgrades to version 3.11.3 after your environment is upgraded to Pega Platform 8.3.

For information on how to manually upgrade to Cassandra 3.11.3, see the Pega Platform 8.3 Upgrade Guide for your server and database at Deploy Pega Platform.

Upgrade impact

After an on-premises Pega Platform upgrade, you still have the older version of Cassandra and must manually upgrade.

What steps are required to update the application to be compatible with this change?

To upgrade Cassandra, you must create a prconfig setting or a dynamic system setting with the new Cassandra version and then do a rolling restart of all the Decision Data Store nodes to upgrade them to the latest version of Cassandra.

MBeans deprecated in favor of Pega API

The use of MBeans for cluster management has been deprecated, although MBeans will continue to function for legacy deployments. The recommended best practice for automating system management is to use the Pega API. For more information, see Pega API.

Pega 7 Platform supports X-Forwarded-* (XF*) HTTP headers

When deployed behind a load balancer, the Pega 7 Platform can formulate absolute URLs while responding to requests, without any additional configuration. The load balancer must be configured to use XF* headers. Consequently, the configuration property contextrewriteenabled is deprecated.

Unified Messaging Desktop integration with Pega Platform

You can now use the Pega Unified Messaging Desktop™ customer service solution with a Pega Platform™ application so that customer service representatives (CSRs) and other users, such as managers, can respond to user requests more quickly and in a more consistent manner. With integrated Pega Unified Messaging Desktop, CSRs can escalate user requests from Pega Intelligent Virtual Assistants™ (IVAs) by using case processing and artificial intelligence alongside Pega Customer Service™

For more information, see Develop a single IVA channel to chat across different messaging platforms.

Improved Pega 7 Platform upgrade and update time

The Pega 7 Platform upgrade and update tools have been improved to streamline indexing. Upgrading and updating are faster than with previous releases.
