Published Release Notes

Referencing Rule tool in Dev Studio

The Referencing Rule tool now runs in Dev Studio without the need for Adobe Flash Player. This enhancement integrates the Referencing Rule tool into your work environment, which improves productivity by reducing context switching.

For more information, see Finding rules by dependency.

PDF/UA support

PDF documents that you generate in Pega Platform™ are now in PDF/UA format. This enhancement improves accessibility for users who rely on assistive technology, such as screen readers.

For more information, see Setting PDF file versions.

Upgrade impact

With an upgrade to Pega Platform 8.4 and later, the underlying PD4ML library in Pega Platform changes from v3.10 to v4.x. Following an upgrade, most standard HTML-CSS conversions to PDF work seamlessly; however, if you use the following custom coding in their application to convert HTML to PDF, you may find that PDF generation works differently than expected or no longer works:

• Application layer Java in activities that directly link to the underlying PD4ML library
• A Rule Utility Function
• PD4ML tags in HTML fragments

For example, the following PD4ML proprietary CSS keywords are no longer supported in v4.x:

• pd4ml-page-break-border-top
• pd4ml-page-break-border-bottom

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

After you upgrade to Pega Platform 8.4 and later and find your PDF generation works differently than expected or no longer works, you should consult the latest documentation available at pd[4]ml support site. You may also consider using the Compact CSS instead of the application skin for PDF generation; for details, see Creating PDF files by using a compact style sheet.

Custom activities protection

Additional activities in table layouts

Table layouts now provide you with the option to run activities either before or after updates to a table. This gives you greater flexibility when you design user interfaces.

For more information, see Configuring table activities.

Semantic URLs in Pega Platform

URL addresses for Pega Platform™ applications and application resources now appear as clear, meaningful paths. This enhancement helps users understand the structure of the application that they are using, which makes navigation quicker and more intuitive.

Support for Thai calendar

Pega Platform™ now supports the Thai solar calendar. The update improves readability for users who rely on this date format, and enhances their experience and engagement.

For more information, see Configuring the Thai calendar.

Guardrail warnings for UI components

Pega Platform™ now displays guardrail warnings about user interface elements that might be high maintenance. With this enhancement, you can ensure that your application meets the latest development requirements for efficiency and ease of use, and save time during future upgrades.

For more information, see Reviewing UI components.

Hierarchical table overhaul

The hierarchical table layout now uses a redesigned architecture that enhances stability and presentation. This update also improves accessibility by implementing ARIA guidelines and introducing keyboard navigation in tables.

For more information, see Creating a hierarchical table layout.

Default support for skip links

All Pega Platform™ access groups now support skip links by default. Before, you had to create special access groups for users who require skip links for screen readers. Now, the feature is automatically enabled for every group, which improves the user experience and simplifies development.

Personalized views in table layouts

Table layouts now provide users with the option to save preferred run-time configurations, such as column visibility and filtering, as permanent profiles. This enhancement helps users create dedicated views for specific work scenarios, which reduces the need for repetitive adjustments to the user interface and improves productivity.

For more information, see Enabling table personalization.

Upgrade impact

After an upgrade to 8.4 and later, the default table toolbar styling and experience may be unexpectedly different for any customized tables in a client's application: if you enabled a tool bar action for a personalizable table and the 8.4 application overrides your customization, your application now displays the default 8.4 table toolbar.

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

Existing clients that upgrade to Pega Platform 8.4 and later may need to update applications in some scenarios. Any custom actions present in the overridden section may need to be re-authored into this toolbar using the additional actions section.
