Version 4.50+ notes

For all release notes, see Tealium for Javascript release notes.

Update your utag.js template to take advantage of the latest fixes and enhancements.

Updating to version 4.50 or later

We recommend the following steps to ensure a smooth transition when updating to version 4.50 or later:

Be sure to update the Tealium Collect tag and all active Consent management templates, especially the Event Logging feature.

• If you have multiple iQ profiles running on the same site, complete these steps to ensure that all instances of utag.js on your site start using the new cookie behavior simultaneously, preventing conflicts or compatibility issues:

  1. Update all utag.js templates to the latest version.
  2. Set the split_cookie override to false on each profile to use legacy cookie behavior and maintain compatibility with older versions of utag.js still running on your site for the duration of the transition.
  3. Once all utag.js templates have been updated and are setting the split_cookie override to maintain the legacy cookie behavior, you can remove the cookie override on all profiles at the same time.

• If you have dependencies on the Visitor ID (v_id) outside of the Tealium Collect tag, set the always_set_v_id option to true to ensure that value continues to be set in time. The most common examples of Visitor ID use are:

  • Cookie sync tags.
  • Mapping tealium_visitor_id to an analytics tag such as Adobe or GA4 for troubleshooting and use in downstream data warehouses.

For more information, see Settings: always_set_v_id.
