What the official record confirms
The USB-IF page confirms the title, publication date and base-specification category. It does not provide a public change summary on the landing page, so technical differences should not be inferred from the version number alone.
Implementation control
Engineering teams should record the exact USB4 revision used in architecture, firmware and validation plans. Adoption of a newer package should pass through technical and legal review because the page also identifies specification-use and adopters-agreement conditions.
Why the update matters
Version tracking across USB4, Type-C and power-delivery documents helps engineering teams keep interface decisions and validation records tied to the correct specification layer.
