> 1.2.2 release notes
> major changes:
> - child restrictions lifted after fork of multithreaded parent
> new features:
> - _Fork function (POSIX-future)
> - reallocarray function (extension from OpenBSD, now widespread)
> - gettid function (kernel tid as supported concept)
> - SIGEV_THREAD_ID sigevent API (Linux extension)
> - tcgetwinsize and tcsetwinsize functions (POSIX-future)
> performance:
> - faster software sqrt on archs without native sqrt instruction
> compatibility:
> - realpath no longer depends on procfs availability & accuracy
> - time zone parser now always prefers 64-bit tables if present
> - crypt_blowfish now supports $2b$ prefix
> - res_query now reports errors via h_errno
> - set*id and setrlimit are now safe in vforked/cloned child
> - setgroups now applies to all threads
> - dlopen debugger notification is improved, should work with lldb
> - setrlimit no longer needs __synccall broadcast on linux 2.6.36+
> - faccessat with AT_EACCESS no longer needs child process on linux 5.8+
> bugs fixed:
> - buffer overflow and infinite loop errors in wcsnrtombs (CVE-2020-28928)
> - sem_close unmapped still-referenced semaphores
> - fork of process with active aio could deadlock or crash paren
> - pthread_cond_wait was broken with priority-inheritance mutex
> - getgrouplist wrongly failed when nscd reported an empty list
> - abort could leak modified SIGABRT disposition to fork or posix_spawn child
> - regression with mallocng: malloc_usable_size(0) crashed
> - readlink wrongly gave EINVAL on zero length dest buffer
> - sqrtl was severely inaccurate (not correctly rounded) on ldquad archs
> - assert failure wrongly flushed stdio (possible deadlock)
> - MUSL_LOCPATH search was broken with multiple components
> - missing newline in herror output
> - possible deadlock in pthread_exit with pshared mutex or barrier usage
> - pthread_mutexattr_getprotocol didn't read back protocol
> - v4l2 ioctl translation for pre-time64 kernels didn't work
> arch-specific bugs fixed:
> - x86_64 longjmp failed to handle 0 argument reliably
> - i386 __set_thread_area fallback for pre-2.6 kernels didn't work
> - missing O_LARGEFILE macro value on x86_64, x32, mips64
> - unpredictable s390x breakage from failure to preserve call-saved registers

Committed, thanks.
