Plain answer

What changes in the next ISO 29148 edition?

The public record shows a third edition at DIS ballot with the same title, committee and scope. It does not publish the draft clauses or a change list, so no one can honestly state a clause level change yet. The practical work is to meet the current edition and keep the references under review.

What is confirmed

ISO records ISO/IEC/IEEE DIS 29148, Edition 3, 101 pages, prepared by ISO/IEC JTC 1/SC 7, with the DIS ballot initiated on 14 September 2026 for 12 weeks. The page says it will replace the 2018 edition. The public abstract repeats the same four purposes and the same three audiences.

What is not public

The draft clauses, the change list and the comment dispositions are not public. ISO sells the draft. The public page gives the stage, the committee, the page count and the abstract. Any clause level claim beyond that is an invention, including on this site.

What is a reasonable inference

A revision that keeps the scope is likely to refine the existing content rather than replace it, and a 101 page draft is in the same range as the second edition. Those are inferences, labelled as such, not findings. They support keeping the current structure and fixing the current gaps.

What to do

Fix the current gaps, complete the four information items, put owners and verification methods on the requirements, and record the edition each specification cites. When the published edition is available, update the references through controlled change. The planning date of 12 September 2027 is an estimate, not a deadline.
