Pega Composite Gateway not required for Pega Web Mashup
Valid from Pega Version 7.2.1
The Pega Composite Gateway servlet (prgateway.rar file) is no longer required for Pega Web Mashup gadgets. You can now use web mashups without deploying the Gateway. Support for the Gateway will continue, but it is a best practice not to use it for the Pega Web Mashup in Pega 7.2.1 and later versions.
Extract marker file not created at startup
Valid from Pega Version 7.2.1
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.
The UpdateAdaptiveModels agent causes an exception after Pega 7.2 to 7.2.1 upgrade
Valid from Pega Version 7.2.1
After the Pega 7 Platform is upgraded from version 7.2 to 7.2.1, the log files might show an error that is caused by the UpdateAdaptiveModels agent. This agent is enabled by default and is responsible for updating scoring models in the Pega 7 Platform. If you use adaptive models in your solution, you can avoid this error by configuring the Adaptive Decision Manager service. If you do not use adaptive models, disable the UpdateAdaptiveModels agent.
For more information, see Configuring the Adaptive Decision Manager service and Pega-DecisionEngine agents.
Reconfiguration of the Adaptive Decision Manager service after upgrade to Pega 7.2.1
Valid from Pega Version 7.2.1
After you upgrade the Pega 7 Platform to version 7.2.1, you need to reconfigure the Adaptive Decision Manager service. Beginning with Pega 7.2.1, the Adaptive Decision Management (ADM) service is native to the Pega 7 Platform and is supported by the Decision data node infrastructure.
For more information, see Services landing page.
Upgrade/update fails if PostGIS is applied to PegaRULES or PegaDATA schema
Valid from Pega Version 7.2.1
If you use the PostGIS extension to a PostgreSQL database, upgrading or updating the Pega 7 Platform fails if the extension has been applied to either the PegaRULES or PegaDATA schema. PostGIS can be applied to any other schema.
Email listeners no longer copy the email subject text to the email body
Valid from Pega Version 7.2.1
As of Pega® 7.2.1, email listeners no longer copy the email subject text to the email body when the body is empty. If your customer application expects text in the body of the email, the application might fail. You can configure email listeners to copy the subject text to the body by using the following Dynamic System Setting:
Owning Ruleset: Pega-IntSvcs
Purpose: email/copyBodyNoContent
Value: true
For more information, see Creating Dynamic System Settings.
Pega Survey documentation refers to deprecated field
Valid from Pega Version 7.2.1
The documentation for Pega® Survey refers to the Answer Layout field on the Complex Question form, but this field is no longer supported. For more information about the question layout formats that Pega Survey supports, see Pega Survey.
Editable list of build-on application features
Valid from Pega Version 8.4
Pega Platform™ now provides you with an option to edit the list of features in your application stack. Now you can define the order of the features to generate application documentation that lists the features by their priorities instead of the time of creation. For example, you can reorder the features when you want to communicate to your stakeholders which elements are top priorities.
For more information, see Learning about feature order.
Enhanced Wait shape
Valid from Pega Version 8.4
Pega Platform™ now supports the enhanced Wait shape that configures the case to wait for the resolution of all child cases instead of only the child cases of a specific type. When you set up the Wait shape to stop a case until it reaches a certain status, you can decide whether the shape considers statuses from a whole case life cycle, or only the statuses after the wait begins. The enhanced Wait shape provides you with greater control over resolution of your cases.
For more information, see Pausing and resuming processes in cases in Dev Studio, Pausing and resuming processes in cases in App Studio.
Improved data page performance
Valid from Pega Version 8.4
Data pages that are sourced from report definitions now support server-side paging. This functionality optimizes the performance and memory of data pages, making them more efficient at retrieving large lists of data. In addition to getting page indicators at the top of a grid, you can sort and filter columns in a grid in conjunction with paging. If you want the system to use server-side pagination, you can also enable pagination from the Data page rule form.
For more information, see Defining data page access.
