Published Release Notes

Improving basic access control

Pega Platform™ has implemented a new basic access control (BAC) to protect your application from unauthorized server calls from otherwise authenticated users.

For more information, see Access Control Checks.

Upgrade impact

After you upgrade to Pega 8.5, all the functionality in the model configurations that use auto-generated controls and actions continues to work as before. However, you must secure any customized JavaScript in your application layer that makes AJAX (server) calls  by using registration or encryption mechanisms.

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

After upgrade, to migrate custom JavaScript functionality, see Access Control Checks.

Addition of Data Access Tab to access control policy condition rules

You can now select associations and declarative index classes when creating access control policy condition rules. The Column source field in the policy condition can now accept properties from available associations and indexes. For ease of reference, the selected associations and indexes are available on the new Data Access tab. 

Using the new tab, you can build complex authorization models in which access restrictions for a class depend on the attributes present in the associated and indexed classes, along with the attributes in the current class. For example, a project management application can now separately maintain project lists for each operator and use that information to restrict read/write access to unique projects.

The information available on the new Data Access tab reflects rule form changes, which are similar to the existing functionality of the Report Definition in the Application Data Model. 

For more information, see Creating an access control policy condition.

Improved UI accessibility

Pega Platform™ now supports W3C Web Accessibility Initiative guidelines more fully, which creates a better user experience for people who rely on assistive technologies, such as screen readers.

The user interface now features the following enhancements:

• Improved keyboard navigation and updated ARIA attributes for layouts, including dynamic, repeating, and table layouts.
• Updated navigation for AJAX and dynamic containers.
• More precise keyboard navigation and focus control for pop-up components, such as SmartTips.
• Fixed accessibility gaps in out-of-the-box actionable controls and form components, such as buttons and text fields.
• More accessible error messages with improved color schemes and focus control. To meet the WCAG ARIA guidelines, the Show next Error bar has been retired and substituted with more accessible error symbols.
• Accessibility code included in the Pega Platform ruleset by default, without the need for additional configuration.

For more information, see Supported keyboard navigation.

Add custom controls to section palettes

You can add custom controls to the Basic or Advanced palettes in sections. With this enhancement, Pega^® Platform developers have easy access to custom controls. The Show in authoring menus check box is available in the HTML tab of the custom control rule. You can add a custom icon to display in the menu with the custom control.

For more information see Adding custom controls to the section palette in Designer Studio.

New JWT access token format: Authorized Access Token

Pega Platform™ is changing from using opaque tokens to using JSON Web (JWT) tokens and the JWT access token format: Authorized Access Token (AAT). An AAT enables a client application to validate the server for user permissions and authorizes a specific application to access specific parts of a user’s data.

The major benefits to using the JWT format are:

• The JWT is a self-contained token that has authentication information, expire time information, and other user-defined claims digitally signed.
• A single token can be used with multiple applications.
• The tokens are short-lived and can minimize damage if transport security is compromised, as the token signature is verified.
• As the token is verified with the signature, there is no need to verify against a database, thus reducing latency (usually important for Web APIs).

For more information, see Understanding authorized access tokens.

Actions available for custom controls

All standard actions that are available for autogenerated controls are available on non-autogenerated custom controls as well. You can configure actions on custom controls by using the legacy actions options or the standard options that are available to custom and autogenerated controls. By using the standard options, developers can now configure multiple action sets for different types of events on a single custom control.

For more information, see Actions tab.

Control group configuration for predictions

You can now configure a control group for your predictions in Prediction Studio. Based on the control group, Prediction Studio calculates a lift score for each prediction that you can later use to monitor the success rate of your predictions.

For more information, see Customizing predictions.

Deprecated support for Microsoft ActiveX controls

Beginning with Pega Platform 7.3, Microsoft ActiveX controls are no longer supported in any version of the Pega Platform, and technical support for ActiveX is limited. It is recommended that you use HTML-based, cross-browser solutions for improved performance and greater security.

For more information, see Deprecation of ActiveX controls in Pega Platform.

Improved access to Cosmos UI settings

The Settings tab in the App Studio case designer now includes tools for configuring Cosmos UI. With this enhancement, you can adjust design system settings without the need to specialize individual When rules in Dev Studio, which simplifies UI creation and saves development time.

For more information, see Managing Cosmos UI settings in case designer.

Ability to restrict access to the Import wizard

You can now restrict access to the Import wizard so that users implement an automated pipeline to deploy changes between environments such as staging and production. Deployment Manager is one method by which to create pipelines. By using pipelines to propagate changes, users can apply a standardized and automated deployment process for migrating their applications.
