The draft wording is feature complete, and is being sent out for international comment ballot. After resolving some ballot comments at the November 2025 standardization meeting in Kona, Hawaii, the C++ Standards Committee is expected to finish resolving ballot comments, technically finalize the draft, and send the draft out for final approval ballot at the following standardization meeting in London, United Kingdom in March 23 to 28, 2026.
Experimental and standard compilers implementing some of the upcoming features can be tried on short code snippets through the Compiler Explorer. Some of the compiler variants are distinguished only by the short identifiers of papers proposing the new features they implement, such as "P3372" for constexpr containers and adaptors.
