Trackingplan now saves the published versions of your Google Tag Manager container, continuously, from the traffic of your site itself. No GTM access to grant, no export to upload.
The agent can read the tags, the triggers, the variables and what changed in each publication, and use that when it explains a warning or answers a question about a release.
Who it is for: teams whose tracking lives in GTM and who want "what changed in release v92?" to be a question, not an archaeology session.
Where: the container appears under your plan once the first hits of a published version arrive. The agent uses it on its own; see also Ask for the cause of a warning.
