Published Release Notes

Support for the decisioning-enabled NLP text analyzer in IVAs and Email Bots

You can now use the new intelligent natural language processing (iNLP) text analyzer in Pega Intelligent Virtual Assistants™ (IVAs) and Pega Email Bots™. This advanced text analyzer is decisioning-enabled and empowers IVA or Email Bot for all conversational channels to provide smarter responses. The decisioning capability in the system integrates text analytics with strategies, prepositions, and interaction history, to provide the context for making better next-best-action decisions.

For more information, see Use the decisioning-enabled NLP text analyzer in IVAs and Email Bots, Defining advanced Facebook text analyzer configuration and Facebook channel behavior.

Upgrade impact

Existing channels remain with the current configuration, and their current functionality does not change. Channels created after the upgrade automatically use the new text analyzer.  

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

The new text analyzer is enabled or disabled using a new interactive API (iAPI) selection, which is selected by default for new channels. You can disable the iAPI for new channels if you want to maintain current functionality. You can also enable it for existing channels if you want to move existing channels to the new functionality.

Improved rich user interface controls in IVA for Web Chatbot

In Pega Intelligent Virtual Assistant™ (IVA) for Web Chatbot, you can use additional rich user interface controls, such as the time and date picker or a simple form, to help users accomplish tasks more quickly and to limit errors. IVA for Web Chat can now also display a welcome message in the chat window, for example, to inform the user about the person with whom they are chatting.

For more information, see Streamline conversations in IVA for Web Chatbot with rich user interface controls.

Upgrade impact

The new Ul controls for Web Chatbot are enabled by default upon upgrade. If you do not want the controls enabled, you must disable them.

Also, if you have changed the styles for the welcome message, you may need to make changes to the welcome message to incorporate the new areas in the bot conversation area (such as quick replies).

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

Existing channels will behave as they did previously, so you should determine whether you want to use the new UI controls. If you want to use the new Ul controls, configure the new design-time options.

If you have changed the default styles for the welcome message, review the new settings to ensure that the welcome message is configured properly. 

Pega Express methodology in App Studio for successful Microjourneys

App Studio now supports the Pega Express™ methodology to help you visualize the key factors of your Microjourneys™ - case types, personas, and data objects. With Microjourneys, you can analyze and clearly communicate who the parties that interact with your cases are, what channels of communication they use, and what data they need to resolve a case. Associating personas and data objects with case types also helps you manage your development team's workload by using a list of the draft elements that they need to develop.

For more information, see Plan successful microjourneys in App Studio (8.4), Creating a microjourney for customer success.

Upgrade impact

During a Pega Infinity™ upgrade to 8.4 and later, clients using App Studio are asked to update their applications to support use of the Pega Express™ methodology. Without this application update, the Persona landing page and Data objects and integration landing page are empty. For more information, see Pega 8.4 Deep Dive: Pega Express methodology in App Studio.

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

In order to utilize the Pega Express methodology in App Studio and use the Inventory page, click Start now to complete the update of your application and add the required rules to it. If you choose to cancel, App Studio continues to work as expected without the Pega Express methodology features; you can click Start now at the top of your application overview page at any time to install the required rules in your application.

Relationships between elements of Microjourneys in application inventory

A new Inventory page in App Studio helps you manage a delivery of your projects by giving you an overview of the elements of your application and how they interact with your Microjourneys™. The new Inventory page lists draft relationships between the case types, personas, and data objects that you want to implement through development. By checking releases that correspond to the items that you need to develop, you can prioritize your work accordingly. 

For more information, see Plan successful microjourneys in App Studio (8.4), Creating a Microjourney for customer success, Managing application inventory.

Upgrade impact

During a Pega Infinity™ upgrade to 8.4 and later, clients using App Studio are asked to update their applications to support use of the Pega Express™ methodology. Without this application update, the Persona landing page and Data objects and integration landing page are empty. For more information, see Pega 8.4 Deep Dive: Pega Express methodology in App Studio.

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

In order to utilize the Pega Express methodology in App Studio and use the Inventory page, click Start now to complete the update of your application and add the required rules to it. If you choose to cancel, App Studio continues to work as expected without the Pega Express methodology features; you can click Start now at the top of your application overview page at any time to install the required rules in your application.

New database tables for email bots

Pega Email Bot™ now uses two new database tables that make the system more reliable and improve system performance. The pc_work_triage table stores complete information about email triage cases for the email bot. The pr_index_tracktriageactions table stores information about captured actions in triage cases.

Upgrade impact

During an upgrade to Pega Platform™ 8.5, a dedicated job scheduler automatically migrates resolved and open triage cases to these email bot tables in the background. If you expose additional properties as database columns or expose additional custom columns in the pc_work table, you must prepare your application for this automated migration. For more information, see Migrating triage cases to new tables.

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

If the pc_work table in your application has no additional properties or custom columns, there is nothing to do; if it does, prior to an upgrade to Pega Platform 8.5, you must extend the pyPopulateColumnNamesExtension data transform to any exposed additional columns in legacy tables with this information.

For more information, see Database schema for email bot tables.

Close button on a pop-up application update removed from App Studio

When you open an existing application that you created in previous releases without support for the Pega Express methodology, App Studio now displays a pop-up window to support Microjourneys™ without a Close button, to improve the usability of App Studio. 

Upgrade impact

The UI automation script might require a change if the script mentions clicking on the Close button.

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

If you have a UI automation script that uses the Close button, update the UI automation script to delete reference to clicking on the Close button.

For more information, see Creating a Microjourney for customer success.

Upgrading to the secure threading mechanism for email bots

In Pega Platform™ version 8.6, Pega Email Bot™ includes a more secure threading mechanism to help track emails from customers and other stakeholders in separate threads for an email triage case.

Upgrade impact

If you upgrade from Pega Platform version 8.5 or earlier, in which you configured an Email channel, perform the following steps to ensure that your system uses the new secure threading mechanism:

• Update the service email rule that the system uses to send an email reply as the initial acknowledgment.
• Update the email reply template in the data transform rule that the system uses when a customer service representative (CSR) sends the reply.

For more information about creating an initial acknowledgment email and email reply template, see Creating outbound email templates. For more information about the secure threading mechanism, see Use a secure threading mechanism in emails.

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

For the initial acknowledgment email used by your email bot, update the service method for your email listener rule. On the Response tab for this service email rule, expand the Message contents section. In the Message data section, you specify the rule that defines the structure of the content of the email body. In Pega Platform version 8.6, you use for this purpose the pyEmailAcknowledgement correspondence rule that takes into account the selected built-in template. This template includes the security code tag that the system uses for the secure threading mechanism. If your application uses a different rule in the Message data section, update this definition to match one of the built-in correspondence template rules, for example, EmailAckTemplate_Clear.

The pySetEmailBotReplyTemplate data transform rule sets the name of the email correspondence rule that the system uses as the email reply template. If you do not want to use the default approach using the Classic, Cobalt, or Clear outbound email template themes, override this data transform rule to set the email correspondence rule name for the Param.ReplyTemplate target in the Source column field.

For more information about how to update the service email rule and the data transform rule to ensure that your system uses the secure threading mechanism, see Upgrading to the threading mechanism available in the 8.6 version.
