Published Release Notes

End of support for Microsoft Internet Explorer 9 in Pega 7.2.1

In accordance with Microsoft’s announcement to discontinue support for Internet Explorer 9, Pega 7.2.1 will not support Internet Explorer 9. You should not upgrade to Pega 7.2.1 if you are still using Internet Explorer 9. Otherwise, upgrade to Microsoft Internet Explorer 10 or later, or use Google Chrome, Apple Safari, or Mozilla Firefox, which support certain HTML5 and CSS3 standards not supported in Internet Explorer 9.

For more information about browser support, see the Platform Support Guide or contact Pegasystems Global Customer Support.

Discontinued support for multithreaded requestors

Multithreaded requestors are no longer supported in the Pega 7 Platform. Multithreading was previously specified by the prconfig setting initialization/allowMultiplePRThreads. If this setting is set to true when you upgrade to Pega 7.2.1, errors occur during the quiesce process.

Child case queries can be slow after upgrade

After upgrading, performance might be slow when you run queries on child cases for work tables that existed prior to the upgrade. This issue is often indicated by PEGA0005 (query time exceeded limit) alerts that can be correlated to these queries in the logs. To resolve the issue, add a database index to each of your work tables by using a multicolumn index on the pxCoverInsKey, pxObjClass, and pyStatusWork columns.

For more information, see Performance improvements for child case queries.

The UpdateAdaptiveModels agent causes an exception after Pega 7.2 to 7.2.1 upgrade

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

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.

Service Portlet rules are deprecated

Service Portlet rules are deprecated. Existing rules will continue to work, but you cannot create new ones. Use Pega Web Mashup instead. In addition, some changes might impact functionality. If you are using Portlet rules and plan to upgrade, contact your customer service representative.

For more information about Pega Web Mashup, see About Pega Web Mashup.

Deprecated metadata types in the Connector and Metadata wizard

The WSDL, SAP WSDL, and DTD metadata types have been deprecated in the Connector and Metadata wizard. For WSDL, use SOAP integration, and for DTD, use XSD.

For more information about SOAP connectors, see About Connect SOAP rules. For more information about XSD, see About the Connector and Metadata wizard.

Deprecated support for passing symbolic index as strings to value lists and page lists

Starting with the next release after Pega Platform™ 8.2, passing symbolic indexes as strings in parameters, properties, and string literals to both value lists and page lists will no longer be supported. The following examples show the syntax that still works in Pega 8.2, that will not work in the next release:

myPageList("<LAST>")

and

param.str = "<LAST>"
myPageList(param.str)

The following example shows syntax that currently is not supported and gives a validation error. This syntax will also not work in future releases.

param.str = <LAST>
myPageList(param.str)

To avoid issues after upgrading to Pega 8.3, refactor all occurrences of this syntax in your code. For instructions on how to find occurrences of this syntax in your code, see Refactoring unsupported symbolic index syntax for value lists and page lists.

For more information about the correct use of symbolic indexes, see Symbolic indexes – APPEND, CURRENT, INSERT, LAST, and PREPEND.

Changes in JSON results when checking the health of your system

Beginning with Pega Platform™ 8.2, the JSON results that are returned when you ping a Pega Platform instance have changed. JSON results now include node type and health information, including test name, status, state, and node ID. The following samples show JSON results from versions before 8.2 and as of 8.2.

JSON results for pre-Pega Platform 8.2:

{ "duration":"3954.448601", "count":"0" }

JSON results for Pega Platform 8.2 and later:

{"node_type":["WebUser"],"health":[{"last_reported_time":"2019-02-14T16:10:49.589Z","test_name":"Sample-Stream-Check","status":"success"}],"state":"healthy","node_id":"10.10.10_samplenode"}.

Improved case auditing in App Studio

In Cosmos UI, App Studio now supports expandable case steps. This enhancement helps users quickly navigate a case and provides deeper insight into the case flow. In addition, Cosmos UI also introduces an improved history view that helps you better meet your business auditing requirements.

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

Upgrade impact

After an upgrade to Pega Platform 8.5 or later, the history and chevron designs change automatically. However, applications with custom history settings might still display the styling that you defined in the override.

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

If your application uses custom settings and you want to use the updated history, remove the overrides from the pyWorkCommonActions rule.
