A new official revision
The document-library record identifies the package as a base specification for USB Power Delivery. The listing does not summarize every technical change, so the complete specification package remains the reference for detailed requirements.
What implementers should review
Product, firmware and compliance teams should compare the new revision with the version used in their current design and test plans. The associated adopters agreements are part of the same official package and should be reviewed by the appropriate technical and legal owners.
Why it matters to charging products
USB PD behavior depends on coordinated implementation across source, sink, cable and test processes. Tracking the current base specification helps reduce the risk of designing or validating against an outdated document.
