Field notes
The inventory separates upcoming deadlines from recent breaking changes and gives each record a stable ID, effective date, category, and source link. At capture, it lists 74 confirmed deadlines and 24 tentative ones across seven ad and martech platforms; a separate tracker covers pricing for 12 GTM tools. The page also lists JSON, MCP, and llms.txt entry points, while Pro and Agency options remain waitlists.
