C++26 is done ISO C++ standards meeting, Trip Report

Summary

News flash: C++26 is done! 🎉 On Saturday, the ISO C++ committee completed technical work on C++26 in (partly) sunny London Croydon, UK. We resolved the remaining international comments on the C++26 draft, and are now producing the final document to be sent out for its international approval ballot (Draft International Standard, or DIS) and final editorial work, to be published in the near future by ISO. This meeting was hosted by Phil Nash of Shaved Yaks, and the Standard C++ Foundation. Our hosts arranged for high-quality facilities for our six-day meeting from Monday through Saturday. We had about 210 attendees, about 130 in-person and 80 remote via Zoom, formally representing 24 nations. At each meeting we regularly have new guest attendees who have never attended before, and this time there were 24 new guest attendees, mostly in-person, in addition to new attendees who are official national body representatives. To all of them, once again welcome! The committee currently has 23 active subgroups, nine of which met in 6 parallel tracks throughout the week. Some groups ran all week, and others ran for a few days or a part of a day, depending on their workloads. We had three technical evening sessions on C++ compiler/library implementations, memory safety, and quantities/units. You can find a brief summary of ISO procedures here.

No features were added or removed; we just handled fit-and-finish issues and primarily focused on finishing addressing the 411 national body comments we received in the summer’s international comment ballot (Committee Draft, or CD).
