Hello, just a note that support for std::format (P0645R10) does not seem to be listed anywhere on the current C++ Standards Support page (https://gcc.gnu.org/projects/cxx-status.html).
I was trying to figure out if it was supposed to be in the 12.3 release or not, but based on PR104166 I guess it's 13+ only. But just in case anyone else is looking for this info... :) Thanks, - C.
