Release Notes

[26-Aug-2025] 

We’re happy to announce a new release for the JavaScript, Browser, and React Native trackers.

This is a small patch release addressing reported cases of invalid events, data consistency, and an issue with using the HTML5 Media Tracking plugin from our Google Tag Manager Tag Template.

Bug fixes

  • Browser/JavaScript trackers
    • Round the browser_context.hardwareConcurrency property, so it is always an integer to match the schema and avoid some invalid events
    • Do not produce a value for dimensions (screen, viewport, document) when a value is non-numeric, which may cause invalid events
  • React Native tracker
    • Make the values automatically collected in the mobile_context more consistent with the values in the v2 tracker
  • Plugins
    • browser-plugin-media-tracking: Allow selecting media elements via CSS selectors rather than just IDs
    • browser-plugin-media-tracking: Prevent a case where the media entity may not populate currentSrc even when it has a src
    • browser-plugin-media-tracking: Update README to match current API
  • General
