Target release notes (current)

These release notes provide information about features, enhancements, and fixes for each Target Standard and Target Premium release. In addition, release notes for Target APIs, SDKs, the JavaScript library (at.js), and other platform changes are also included, when applicable.


mbox.js end-of-life: On March 31, 2021, Adobe Target will no longer support the mbox.js library. Post March 31, 2021, all calls made from mbox.js will gracefully fail and impact your pages that have Target activities running by serving default content. We recommend that all customers migrate to the most recent version of the new Adobe Experience Platform Web SDK or the at.js JavaScript library before this date to avoid any potential issues with your sites.

  • Adobe Experience Platform Web SDK: The Adobe Experience Platform Web SDK lets you interact with the various services in the Experience Cloud (including Target) through the Adobe Experience Edge Network. If you choose to migrate to the Adobe Experience Platform Web SDK, see What is Adobe Experience Platform Web SDK in the Web SDK Guide.

  • at.js: The at.js JavaScript library provides many advantages over mbox.js. Among other benefits, the at.js improves page load times for web implementations, improves security, and provides better implementation options for single page applications. If you choose to migrate to at.js, see How At.js Works and Adobe Target Skill Builder: Developer chat, migrate Adobe Target’s mbox.js to at.js.

Although, mbox.js is currently supported (until March 31, 2021), we have not provided feature updates to this library since July 2017. By moving all customers to the Adobe Experience Platform Web SDK or at.js, our engineers and support staff will be able to provide you with new functionality and offer the support you have come to expect from Adobe.

Target Standard/Premium 21.1.1 (January 19, 2021)

This maintenance release contains the following enhancements, fixes, and changes.

The issue numbers in parentheses are for internal Adobe use.

  • Added a warning when selecting an Adobe Analytics metric when using Analytics as the reporting source (A4T) in an Auto-Target activity. Auto-Target models are optimized to work with binary (conversion-based) metrics. Selecting a continuous metric, such as revenue, might have sub-optimal outcomes and the Personalization Insights reports might not be accurate. (TGT-38926)
  • Added a status icon in the Auto-Target Summary report for Auto-Target activities that use A4T. The green check icon next to each experience in the report indicates that a personalized machine-learning model has been generated for that experience. The clock icon indicates that not enough traffic has been served to build the model. (TGT-38925)
  • The Automated Segments and Important Attributes reports for Auto-Target activities that use A4T and Analytics conversion metrics are generated and look the same as when using Target as the reporting source. (TGT-38931)
  • Added an environment filtering option to the Recommendations Collections list. (TGT-38353)
  • Fixed an issue that caused the incorrect product count to display in Recommendations collections. (TGT-39162)
  • Added a Last Updated filter to the Recommendations Catalog Search. (TGT-38340)
  • Fixed an issue in Recommendations that caused the Create Sequence page to hang after changing the industry vertical. (TGT-38160)
  • Fixed an issue that prevented the activity from being saved if Device Co-op was enabled and the user changed from Target as the reporting source to Analytics (A4T). (TGT-38163)
  • Fixed an issue that prevented users from removing an audience from an offer in an Automated Personalization (AP) activity. (TGT-39058)
  • Fixed an issue that caused the incorrect time frame (start and end dates) to display in Audience Info cards for some customers. (TGT-39150)
  • Fixed an issue that prevented some customers from seeing the list of activities in the Default Workspace. (TGT-38526)

at.js 2.4.0 (January 14, 2021)
