- Get threads working on NetBSD - Get threads working on OpenBSD - Fix Emacs config for Emacs v28 - Improve --strace logging of sigset_t - Improve --strace logging of struct stat - Improve memory safety of DescribeThing functions - Refactor auto stack allocation into LIBC_RUNTIME - Introduce shell.com example which works on Windows - Refactor __strace_thing into DescribeThing functions - Document the CHECK macros and improve them in NDEBUG mode - Rewrite MAP_STACK so it uses FreeBSD behavior across platforms - Deprecate and discourage the use of MAP_GROWSDOWN (it's weird)
