Condition builder enhancements
Valid from Pega Version 8.5
To enhance the precision of condition builder in both App Studio and Dev Studio, the new instances include comparator helps you specify the number of field group and field group list instances to which a when rule applies. In addition, a search option that returns results on keypress helps you easily look for existing values.

Support for nested Declare Trigger rules
Valid from Pega Version 8.5
Pega Platform™ now supports nested Declare Trigger rules so that you can conveniently create correlations between actions in your case types. Declare Triggers rules invoke an action when a specified event takes place in a case type. You can now design more complex scenarios faster by nesting more Declare Trigger rules that work in the context of running another Declare Trigger rule. For example, when a case participant changes a postal code in their personal details, a Declare Trigger rule runs and a respective customer service representative (CSR) receives an email. After the CSR receives the email, a nested Declare Trigger rule runs and your application creates a document with the updated personal details and attaches it to the case.
For more information, see Develop applications faster with nested Declare Trigger rules (8.5), Declare Trigger rules.
Support for validations in Declare Expression rules
Valid from Pega Version 8.5
Pega Platform™ now correctly evaluates validations on target properties in Declare Expression rules. As a result, any validations defined on properties that have Declare Expression rules in previous releases, now work correctly.
Upgrade impact
Any unintended validations on properties that have configured Declare Expression rules, both default and user-defined, might cause issues in an application upon saving work objects and data objects that refer to Declare Expression rules.
What steps are required to update the application to be compatible with this change?
If you experience issues when saving objects, debug your application by setting the declareexp/target/validation/disable dynamic system setting to true. If your application works correctly after the change, it means that validations on Declare Expressions cause the issues. For your application to work correctly, analyze the log files and remove any unintended validations.
For more information, see Declare Expression rules.
Upgraded selected third-party JAR files to support Pega Platform functionalities
Valid from Pega Version 8.6
Pega Platform™ 8.6 now provides upgraded versions of the JAR files that support various functionalities within the Platform, such as generating documents or PPTX files.
Upgrade impact
If you have custom implementations and use any classes from the upgraded JAR files directly in your code or through JAR APIs, after your upgrade to Pega Platform 8.6, your application might experience unexpected run-time behavior if the upgraded JAR version lacks any elements from the previous version. For example, custom implementations can typically include activities, functions, or non-autogenerated sections. Unexpected run-time behavior might also occur when you use a third-party library that has dependencies on the upgraded JAR files. If you use only default Pega Platform functionalities without any customizations, the JAR files continue to work correctly without any additional actions.
What steps are required to update the application to be compatible with this change?
If you have any JAR customizations, ensure that you test the upgraded JAR files for compatibility and upgrade impact. The following table lists the upgraded JAR files that might impact your application:

Enhanced Pulse gadget for Cosmos React
Valid from Pega Version 8.6
Together with the DX API, the Cosmos React component now provides an overlay in which users can quickly view and select the feed sources from which to view Pulse messages. Users can also add attachments to their messages, and remove the messages that they post. These enhancements improve collaboration and speed up case resolution. For example, a case worker can view only posts from particular cases, to quickly find a request for additional information about a case, and then provide necessary details by attaching a relevant document.
