Published Release Notes

Extract marker file not created at startup

The extract marker file (PegaRULES_Extract_Marker.txt) is not created at startup, because the rule utility libraries no longer need it. If you used to use the extract marker file to clear the static content file-based cache, to look up lists, or to control starting activities with web nodes, you can delete the contents of the PegaRULES temporary directory instead.

Enhanced tables in Cosmos React UI

The Pega Platform™ Cosmos React UI environment now includes improved tables. The updated tables use a revamped graphic design and support a number of new run-time behaviors, including column freezing and advanced filtering. The added features improve the user experience by giving case workers more control over data in tables, while the revised architecture enhances efficiency and reliability.

Deprecation of override rulesets in run-time ruleset lists

Pega 7.2.1 is the last release where override rulesets can be incorporated in the run-time ruleset list. The ability to create override rulesets was originally deprecated in Pega 7.1. However, any override rulesets that were created in releases prior to Pega 7.1 in the application ruleset lists were still incorporated into the run-time ruleset lists at the appropriate location. In releases after Pega 7.2.1, override rulesets will be ignored and will not be incorporated in the run-time ruleset list. Therefore, it is recommended that you use production rulesets in access groups instead of override rulesets.

Hierarchical table overhaul

The hierarchical table layout now uses a redesigned architecture that enhances stability and presentation. This update also improves accessibility by implementing ARIA guidelines and introducing keyboard navigation in tables.

For more information, see Creating a hierarchical table layout.

Response timeout configuration for predictions

You can now set a response timeout for your predictions in Prediction Studio. By setting a response timeout, you control how Prediction Studio registers customer responses that later serve as feedback data for your predictions.

For more information, see Customizing predictions.

Design templates in Pega Express

You can now use design templates to control the layout of form fields in Pega Express. Use the form builder Layouts tab to select a layout for the form and organize the fields in the layout regions.

For more information, see Adding a design template to a form in Pega Express.

Rule form search

You can now search for content within some rule forms by clicking Search rule on the Actions menu. The search results and the tabs of the rule form that contain the search results are highlighted.

For example, you can find the properties that are used in a when condition inside an activity without navigating to each tab, when condition, transition, and method in the activity.

Custom application URL alias in the application definition

Create application URL aliases that support your ability to launch multiple Pega applications simultaneously in a single browser. This feature makes it easier for clients and your customers to log into multiple applications using the same browser and access them simultaneously. You configure your application URL alias in the application definition. For details, see Adding an application URL alias.

For more information, see Simplify access with an Application URL alias (8.4). 

Upgrade impact

After an upgrade to Pega Platform™ 8.4 and later, review to determine if and how you must update your application rules to reflect the current URL aliasing format. As part of these application rule updates, Pega also updated the URL format and value components of the clipboard property, pxRequestor.pxReqServletNameReal, which you can use to discover a servlet name. If your application uses this property to discover a servlet name, update the pxRequestor.pxReqServlet property in the application rule to use the new, required URL and value formats.

For details steps, see the section, Upgrading from Pega 8.3 or earlier: Guidelines for any required changes in your application URL aliasing, in the appropriate Pega Platform Upgrade Guide available at Deploy Pega Platform. 

What steps should the customer take to update their application?

After upgrading, you must update your JMeter test scripts. For detailed steps, see Updating JMeter test scripts after migrating to Pega 8.4.

Email approval and instantiation not supported on multitenant systems

The Enable email approval check box appears on the General tab of an approval step in Case Designer in multitenant systems. It also appears on the Approval shape in Designer Studio. In addition, in Designer Studio, the Settings tab in Case Designer displays the option to configure email instantiation. However, because configuring email listeners is not supported on multitenant systems, you cannot enable email approval or email instantiation.

Ignore browser and operator locale to display Designer Studio in English

The operator preferences configuration includes the option to ignore the browser and operator locale. Some rulesets are shared between Designer Studio and end-user portals. Translated words might occasionally display in Designer Studio. Selecting the Ignore locale check box ignores the locale of the operator and browser to display Designer Studio portals in U.S. English only.

For more information, see Updating Designer Studio preferences.
