Sutter's Mill

The ISO C++ committee completed its first fit-and-finish meeting for C++26 in Kona, with 200 attendees representing 21 nations. Key decisions included keeping contracts in C++26 with bug fixes, removing trivial relocatability due to a showstopper bug, and improving erroneous behavior semantics. The committee resolved 70% of international comments and is on track to finalize C++26 in March 2026. Leadership changes were announced: Guy Davidson becomes the new convenor, with Nina Ranns and Jeff Garland as vice-convenors, and Braden Ganetsky as secretary. Herb Sutter steps down as convenor after serving since 2002 but will remain active in the committee.
