Published Release Notes

New branch quality dashboard

Pega Platform™ 8.4 introduces a new branch quality dashboard that shows the following metrics:

• The branch’s guardrail compliance score and the number of guardrail violations
• The percentage and number of unit tests that passed for the branch
• The percentage and number of rules that the tests cover
• Potential merge conflicts that can be addressed directly from the branch quality dashboard

For more information about the new branch quality dashboard, see Viewing branch quality and branch contents.

Autopopulated properties support savable data pages

To more easily source data, you can now save an autopopulated property that references a savable data page. For properties that you autopopulate by copy, save plans now execute on the copy, instead of on the data page. These enhancements reduce implementation time and make the applications that you build more manageable.

Improved reliability of Visual Business Director

Improvements to the reliability of Visual Business Director (VBD) eliminate the impact of temporary access loss to the VBD cluster. The improvements include the ability to continue writing data to a VBD dataset while the corresponding server node is unavailable, enhancements to single-case data flows that write data to VBD, and a reduction in the VBD cache size.

For more information, see Eliminate the impact of temporary access loss to the VBD cluster (8.4).

Support for the Unified Messaging channel

You can now create a Unified Messaging channel so that users can interact with a Pega Platform™ application by chatting in Pega Intelligent Virtual Assistant™ (IVA), for example, through Apple Business Chat, Facebook Messenger, Twitter, or a web chat window. The Unified Messaging channel is quick to develop and uses an integrated customer service platform to provide a completely new user experience. You can optionally also integrate a Unified Messaging channel with the Pega Unified Messaging Desktop™ customer service agent solution.

For more information, see Develop an IVA channel to chat across multiple social messaging platforms, Unified Messaging channel overview, and Creating a Unified Messaging channel.

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.

Strategies are now available as a condition type in proposition filters

When designing proposition filters, you can now include strategy outcomes as a condition to be evaluated. Select a strategy and specify the component that you want to use as output to include more advanced decisioning in your proposition filters.

For more information, see Enrich your Proposition Filter rules with conditions based on strategy results.

Client-server deployment of Hazelcast

Pega Platform™ now supports the client-server model for the Hazelcast service, which provides cluster communication and distributes Pega Platform features across nodes. This optional deployment model introduces independent scalability for both servers and clients in Pega Platform, improving stability for deployments that use a large number of nodes.

The Hazelcast client-server model is intended for select environments running Pega Platform 8.4 across a large number of nodes and should be deployed only when directed by Global Client Support.

Improved mobile app user experience

Pega Platform™ can now produce a better mobile experience through performance gains and flexible access settings. Apps now support quick-loading native worklists, smooth scrolling and swiping, and query-based search, which improve productivity for mobile users. In addition, you can make your app available to users without authentication, and enhance usability for products that do not require strict security controls.

For more information, see Securing mobile apps.

Default text analytics model for detecting small talk

Enhance your web chat experience by configuring chatbots to detect small talk. Pega Platform™ provides the default model that is a topic detection model, available for English, German, Spanish, Dutch, Portuguese, Italian, and French.

For more information, see Configure your chatbot for small talk.

More efficient mobile development

The work environment for mobile app developers in Pega Platform™ is now more intuitive. Because every new out-of-the-box application now comes with a preconfigured mobile channel, you can start building mobile apps straight away. Create a mobile channel from scratch, and then customize it to include specific requirements for your new app.

The following updates enhance the process of building mobile apps:

• Your application stores all mobile channels as rules. You can reuse these channels across all versions of your mobile apps for more convenient updates.
• You can now configure contextual search from the mobile channel.
• You can now create native mobile list pages for the app navigation directly from the mobile channel.
• You can now add pages from web portals to a mobile app navigation pane, with full support for native mobile features, such as floating action buttons.
• Mobile channels now support configuration through predefined templates, widgets, and actions.
• You can now instantly preview your mobile channel configuration to see how the app displays on mobile devices.
• Configuration of offline support for mobile apps is now available from a single, low-code page.
• The preview section now offers a low-code pane, from which you can instantly start building a mobile app.
• The mobile channel now supports adding custom iOS and Android modules.
• Admin Studio now supports a mobile page, from which you can provide your own Mobile Build Server credentials and decide whether users need to provide authentication to download your mobile app.
