Published Release Notes

Use Page-Change-Class method to change a Page class

With the release of Pega Platform™ 8.3, using the Property-Set method to change the Page class shows a guardrail warning. Use the Page-Change-Class method to change the Page class instead.

For more information about the Page-Change-Class method, see Changing the class of a page and Page-Change-Class method.

CyberArk password vault support added for Pega database

With the CyberArk password vault, you can store your systems' passwords in a secure, central location and retrieve them from that location instead of directly entering credentials into the systems. This support is available only for IBM WebSphere environments.

For more information, see Pega Platform deployment guides.

Support added for multiple mashups

You can now include multiple mashups on a single webpage or browser, even if the mashups have different application and authentication requirements. Use mashups to embed a Pega Platform™ application as a gadget on your website. For example, you can embed Web Chatbot and Self-Service Advisor on the same website.

For more information about mashups, see Configuring the Mashup channel.

Changes to URL format for Pega Web Mashup

The format of Pega Web Mashup URLs now supports multiple mashups on a single web page. The new URL format prevents a mashup from sharing cookies with another mashup.

If you want to include multiple mashups on a single web page and one of the mashups was created before 8.3, you must regenerate the mashup to reflect the new URL format.

For more information, see <link to help topic>.

Change tracking tab removed from declare expressions

To simplify the configuration of a declare expression, the Change tracking tab has been removed from the declare expression rule form. To use the Change tracking tab, on the declare expression rule form, click Actions > Use legacy expression.

For more information, see Supported and unsupported configurations in simplified declare expressions.

Upgrade impact

The declare expression rules have been moved from the pr4_rule table to the new pr4_rule_declare_expression table.

The upgrade can fail if you customize the pr4_rule table, such as increasing the length of an existing column.

After a successful upgrade, the declare expression rule form is simplified and lightweight pages support declare expressions.

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

Read-only data pages by default are lightweight. You could also enable lightweight pages for:

• Editable data pages by selecting the Enable option in the editable data page rule form.
• For all pages in a REST service by using the Lightweight clipboard mode in the Service REST form in the Rest API service.

Only simplified declare expressions are supported in lightweight pages. In simplified declare expressions, context-bound rules are not supported. However, a page context could be specified on the New or Save As form of declare expressions. For more information, see Declare Expression rules - Completing the New or Save As form.

Redirectguests mashup configuration has been removed

The authentication/redirectguests server configuration and data-pega-redirectguests attribute have been removed and are no longer required when you configure a mashup. This prevents you from needing to maintain multiple nodes to support some use cases that require the configuration value to be true and other uses cases that require the configuration value to be false.

For more information, see Configuring the Mashup channel.

Improved search indexing performance

Search indexing now uses a queue processor to improve indexing performance. Indexing can automatically restart if the database goes down temporarily. This saves time and manual action. As a result of using the queue processor for indexing, the following changes have been made to the Search Landing page.

• You cannot cancel indexing from the Search landing page. Cancel indexing by stopping the queue processor from the Data flow landing page.
• The progress message is not shown. View progress on the Queue Processor landing page.
• Queue processor information has been added.

For more information, see Stopping or pausing search reindexing.

More visibility of your production level

You can now see the production level of your environment in a new gadget that is available in all Pega Platform™ workspaces. To ensure that you immediately recognize your current environment, you can give it a unique name that is displayed when you click the gadget. In addition to specifying your production level and environment name on the System form in Dev Studio, you can now specify those values on the System & nodes page in Admin Studio.

For more information on Admin Studio, see Modifying your environment name and production level.

For more information on Dev Studio, see Specifying the production level.

Rule revalidation after updating properties without restarting nodes

When you update certain property attributes, such as a property's maximum length, rule types that reference the property might not reflect the change. You do not always have to restart nodes to revalidate the referencing rules when they cannot be resaved, for example, when they are in a locked ruleset. For Pega Platform™ 8.1 and later, for non-stream rules, such as activities, data transforms, and so on, use the reassemble API in Admin Studio or truncate the assembled classes table.

For stream rules, such as sections, harnesses, paragraphs, and so on, reassemble the rules and restart the nodes. For more information, see More about properties.

For previous versions of Pega Platform, use the System Management Application (SMA) to revalidate stream and non-stream rules.

Improved management of batch indexing

You can now cancel and check the status of a batch index process directly from the Search landing page in Dev Studio. The landing page now refreshes automatically every 10 seconds so that you can easily see the most recent status of the batch index process. Additionally, the reindex operation is now 20% faster than in previous versions. These features provide greater visibility into batch indexing and improve your ability to fix issues with a batch indexing process.

For more information about batch indexing, see Rebuilding search indexes from the user interface.
