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.

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.

Default value of the threadpoolsize agent affects batch indexing
Valid from Pega Version 8.5.2
After you patch Pega Platform to version 8.5.2 or higher, the system changes the default value of the threadpoolsize agent, which controls the number of concurrent activities (threads) in the system, from 5 to 15. Batch indexing in Pega Platform™ does not require all 15 threads, so you can change the agent value to increase system performance by managing the indexing/distributed/batch/numworkers dynamic system setting.
If your deployment does not support that setting, and batch indexing does not use Queue Processors, the system uses the threadpoolsize value for batch indexing instead.
