Published Release Notes

Support for predictive models in PMML version 4.4

Pega Platform™ now supports the import of predictive models in Predictive Model Markup Language (PMML) version 4.4. With this feature, you can import PMML models that use the anomaly detection algorithm.

For a list of all supported PMML models, see Supported models for import. 

Support for advanced validation of embedded and referenced data

To help you define validation conditions for a broader range of use case scenarios, Pega Platform™ now supports stage entry validation for embedded fields in the form of a validation matrix. You can now define validation conditions for both field groups and field group lists, and easily navigate between them. You can also select any fields and when conditions while building a condition for both field-level and stage-level validation.

For more information, see Validating field values for stage entry.

Complete email and notification approval in App Studio

App Studio now supports complete email approval configuration directly in the Case Designer. Email approval settings now include composing a new message or selecting a template, saving templates to a library for future reuse, and adding attachments to an email. Additionally, you can now send the approval as a push notification to mobile users. With full configuration of email approval in App Studio, you save time and create unique and personalized email messages and push notifications in a no-code, intuitive way. 

For more information, see Obtain approvals from email and push notifications from App Studio (8.5), Requesting approval by email and push notification.

Business logic routing of approval steps

Pega Platform™ now supports routing of approval steps by applying business logic, in both App Studio and Dev Studio. Business logic uses a set of conditions to determine the most appropriate worker to approve a case by routing the approval based on defined conditions. For example, in a loan request case, the application can route the approval step to a manager if the importance of the case is set to high. For greater accuracy, business logic can also use skill set, availability, and workload to determine the appropriate worker. With business logic routing, you increase work efficiency and speed up case resolution.

For more information, see Determine a relevant case approver by using business logic (8.5), Requesting approval from users.

Low-code styling in mobile apps

The mobile channel now supports enhanced low-code styling and branding of mobile apps. For example, you can customize app icons in three different ways: by uploading an image, by selecting from a list of font icons, or by using the default text-based icons. This enhancement helps you to conveniently customize the look of mobile apps to match the branding guidelines of your company and provide a consistent experience for users across different channels.

For more information, see Applying a custom theme to mobile apps.

Offline support for Cosmos-based mobile apps

Mobile apps that are based on the Cosmos design system now support offline mode. Previously, offline-enabled apps had to rely on the classic look. Now, you can use the low-code Cosmos solutions to design apps that operate reliably regardless of the connection status. 

For more information, see Designing apps for offline mode.

Removal of Pega Mobile Client 7

You can now use a single Pega Mobile Client™ that improves app performance, app development, and meets all your mobile needs. With the introduction of new functionalities for mobile apps, Pega Mobile Client 7 is removed in Pega Platform™ 8.5.

Upgrade impact

After an upgrade to Pega 8.5, you can no longer build mobile apps based on Pega Mobile Client 7, and existing apps based on Pega Mobile Client 7 no longer connect to Pega Platform. App developers can now configure mobile apps with Pega Mobile Client.

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

Existing clients that upgrade to Pega 8.5 are automatically switched to Pega Mobile Client.

Limits on active data flow runs

You can now configure a maximum number of concurrent active data flow runs for a node type. Set limits to ensure that you do not run out of system resources and that you have a reasonable processing throughput. If a limit is reached, the system queues subsequent runs and waits for active runs to stop or finish before queued runs can be initiated, starting with the oldest.

For more information see, Limit the number of active runs in data flow services (8.5).

Upgrade impact

If you have many data flow runs active at the same time, you might notice that some of the runs are queued and waiting to be executed.

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

You do not have to take any action. After the active runs stop or finish, the queued runs start automatically. The default limits are intended to protect your system resources, and you should not see a negative impact on the processing of data flows. However, if you want to allow a greater number of active data flow runs to be active at the same time, you can change the limits. For more information, see Limiting active data flow runs.

Support for Apache HBase 2.1 and Hadoop 3.0

Support for these versions extends Pega Platform™ compatibility with HBase releases to ensure that your database implementations integrate seamlessly with Pega Platform.

Pega Platform now supports:

• Apache HBase 2.1 for the HBase data set
• Apache Hadoop Distributed File System (HDFS) 3.0 for the HDFS data set

For more information, see Enhance your data sets with Apache HBase 2.1 and Hadoop 3.0 (8.5).

Web portal reuse removed from the mobile channel

The reuse of web portals for creating mobile apps with a single web view is no longer supported. You can conveniently update your existing channels that reuse web portals to take advantage of the multiple-views experience and native mobile capabilities, such as native mobile list views or floating action buttons.

Upgrade impact

The Reuse web portal option is removed from Pega Platform 8.5 and later.

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

App developers need to use the migration tool available on the mobile channel to move their apps to the recommended new navigation designer. When users open existing mobile channel with the Reuse web portal option configured, they are prompted to run through the wizard to upgrade the mobile channel to the latest Pega Mobile Client based configuration. When this is done, app developers should rebuild the app.
