Published Release Notes

Embedded properties in DX API v2 requests are no longer removed

In Pega Platform version 8.5, when you use the POST and PATCH v2 DX API methods with an embedded page property included in the content element of the request, the system removes all properties in the embedded page that are included in the case but are not a part of the request. Now, the merge logic has been modified to update embedded page fields sent up in the request, and keep other fields unchanged.

This feature simplifies client code and prevents data corruption.

Improvements to the HBase data set, HFDS data set, and Hadoop host configuration

The Pega 7 Platform features maintenance improvements to the Hadoop host configuration, HBase data set, and Apache Hadoop File System (HDFS) data set. System architects can more easily make HDFS and HBase storage available to business scientists for exploratory analysis and predictive model building.

For more information, see Big data functionality enhancements.

HDFS data sets support Parquet files

The Parquet file format has been added to the list of supported file formats for data storage in the Hadoop Distributed File System (HDFS) data set record. On the Pega 7 Platform, you can now access an HDFS data set that stores data in the Parquet file format and perform various operations on that data set.

For more information, see Big Data enhancements in decision management.

Text analytics infrastructure upgraded to Java version 1.7

The JAR libraries that support the text analytics features of the Pega 7 Platform have been upgraded to Java 1.7. As a result of the upgrade, you can validate the Ruta scripts that contain entity extraction models and view error reports if the imported Ruta scripts are invalid. This upgrade helps you to ensure that the structure of the entity extraction models that you import to your application is always correct.

For more information, see Text Analyzer.

Know the real-time status of operators

You can get the real-time availability status of all logged-in operators. The status of each operator is maintained by the Pega 7 Platform in a presence record. You can receive real-time status change notifications by subscribing to the Operator Presence channel or by querying the presence record directly.

For more information, see Tracking the online presence of operators.

Upgraded rich text editor

Content that you copy from a word processor or spreadsheet and paste into the upgraded rich text editor keeps its original formatting. You can paste text and tables into a Pega^® Platform application without losing formatting or styles.

For more information, see Rich text editor.

Post Pulse messages to cases from a push notification screen

If your mobile device uses Android 7.0 or later, or iOS 9.0 or later, you can now respond to Pulse messages in Pega^® Platform cases without opening a custom mobile app. Push notifications received on a mobile device now display a Reply button so that you can respond immediately to the notification.

For more information, see Notifications.

Nodes in a cluster do not see each other for Docker, multiple VMs, or multiple NICs setup

If a cluster is set up in Docker, or uses separate virtual machines (VMs) or multiple network interfaces, you must set the public address in the prconfig.xml file for each Pega^® Platform node to avoid problems with node clustering. Add the <env name=”identification/cluster/public/address” value=”IP address”/> setting to specify the public address that is used by each node.

VTable dispatch mechanism for HTML control execution improves performance

Pega® Platform now uses an optimized VTable dispatch mechanism to manage rule execution for the Text Input and Formatted Text Input controls. This change improves performance by eliminating the dependency between stream rules and HTML controls during rule assembly. Disabling this feature will have a negative effect on performance and is not recommended. However, you can disable this feature by adding the following configuration parameter:

Name: assembly/section/control/vtable
Value: false

Support for regular performance alerts

You can now specify how often Pega Platform™ sends you performance alerts about SLA violations in data flow runs. By default, the interval is 5 seconds for single case data flows and 5 minutes for batch and real-time data flows.

The following dynamic system settings control the alert interval:

• Single case runs: dataflow/singlecase/alert/throttleTime
• Batch runs: dataflow/batch/alert/throttleTime
• Real-time runs: dataflow/realtime/alert/throttleTime

For more information, see PEGA0062 alert: Data flow execution time above threshold.
