Snowplow JavaScript Tracker 4.10.0
Last updated: July 30, 2026
This release focuses on webview and single-page app tracking. A new opt-in webview plugin is available as a build-time feature flag, along with an option to disable session context inside webviews so that hybrid apps don't emit conflicting session data. SPA tracking also gets a preserveOriginalReferrer option for holding on to the original referrer across route changes, plus a startup performance fix that removes a forced layout read during tracker initialization.
