The final draft of ISO C 23 is available: https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3047.pdf and the editor was so nice to summarize what's in it: https://thephd.dev/c23-is-coming-here-is-what-is-on-the-menu
For Gnulib, the most interesting additions are: - <stdbit.h> - <stdckdint.h> - memset_explicit. But there's more; see the Annex M.1 for details. Bruno
