<description>Effective Oct 2, 2026. Google notified container owners that Google Tag Manager (gtm.js) snippets will no longer recognize or wait for gtag(&#39;config&#39;) commands; from October 2, 2026 all gtm.js snippets initialize on container load regardless of any config command. Sites that load a GTM snippet but rely on gtag(&#39;config&#39;) to pass parameters or configure Google Ads or GA4 tags must switch to the gtag.js snippet or use the new gtm init trigger.

<description>Google announced the unification of Google tag and Google Tag Manager: Google tags become fully capable GTM containers (interface tagging, debugging, version control), containers send data directly to Google destinations instead of loading a separate gtag.js, Google tag settings are centralized as Destinations, and new snippets use a &#39;gtm init&#39; trigger. Adoption is opt-in via in-account optimization prompts; nothing changes automatically.

<description>Effective Apr 10, 2025. Containers with Google Ads or Floodlight tags load a Google tag first (with the tag&#39;s full configured settings) before sending events. Because the auto-loaded tag inherits settings, user-provided data collection can activate where the Google tag allows it and enhanced conversions are on.
