- Open flags (e.g. O_CREAT) are now constants - Error numbers (e.g. EINVAL) are now constants - Signal numbers (e.g. SIGINT) are now constants - fcntl() file locks now work properly on Windows - Significantly improve Windows path handling code - Implement true vfork() on Windows and make fork() faster - Implement scanf %[charset] support and improve conformance - Introduce $COSMOSDRIVE so you can use Windows 11 dev drives - Fix stdio seek/tell bug and make stdio locks faster and safer - Change TLS ABI to use tlscc wrapper that inserts function calls - Make malloc() faster on all platforms using new cosmo_shard() api - Make malloc() fast like tcmalloc on Linux using restartable sequences - Improve fsync() and fdatasync() polyfills so they abstract robustness - Fix CLOCK_BOOTTIME and CLOCK_MONOTONIC on XNU so it reflects uptime - Fix bugs in Windows overlapped code that could possibly cause crash - Fix bugs in Windows signal code that could possibly cause crash - Make symlinks with multiple components work right on Windows - Add FreeBSD ELF note to remove SIGBUS issue and other quirks - Support symlinks on Windows under non-administrator accounts - Make kisdangerous() scalable by adding radix trie to mmap() - Make large realloc() operations zero-cost on all platforms - Fix bugs in readdir() on Windows where d_reclen wasn't set - Make all system call wrappers memory safe (raises EFAULT) - Fix bugs in poll() and select() on Windows with 64+ fds - Fix bug in madvise() on Windows that could cause crash - Support WUNTRACED, SIGSTOP, and SIGCONT on Windows - Increase x86 image base from 0x400000 to 0x4200000 - Introduce -msysv and -mtinylinux flags to cosmocc - Fix issues with siglongjmp() on XNU and NetBSD - Make pthread_barrier_wait() work correctly - Make clock_gettime() faster on FreeBSD ARM - Support file mode bits better on Windows - Improve performance of string libraries - Raise EILSEQ when creating evil paths - Fix std::terminate to not use malloc - Modernize more c11 and c23 features - Make pthread_once() exception safe - Support RLIMIT_CPU on Windows - Introduce HACL* cryptography - Introduce cosmopolitan make - Introduce fasterzip program - Introduce open_memstream() - Introduce dedupe program - Introduce arc4random() - Introduce f2fs support
