@@ -2200,3 +2200,90 @@ arch-specific bugs fixed:
 - arm dynamic linker chose wrong tls/atomic variants since 1.1.21
 - some math library functions returned excess precision on i386
 - unconfirmed regression in fchmodat AT_SYMLINK_NOFOLLOW on mips*

+
+1.2.1 release notes
+
+major changes:
+- new malloc implementation (mallocng & overhauled bump allocator)
+
+new features:
+- DNS queries via res_* now set AD flag, report zone signedness (DNSSEC)
+- PTHREAD_NULL macro (POSIX-future)
+
+performance:
+- optimized memcpy and memset for aarch64
+- optimized memcpy for arm now supports big endian
+- optimized x86_64 remquol
+- improved strerror without linear search
+
+bugs fixed:
+- lock-skipping for processes that returned to single-threaded was wrong
+- AF_UNSPEC dns lookups mishandled single failure in paired A+AAAA
+- res_send and res_query returned wrong value on errors from nameserver
+- corrupted sysvipc timestamps on 32-bit archs with old kernels
+- incorrect parsing of timezone offsets after overly-long zone name
+- clock_adjtime was broken on 32-bit archs (time64)
+- pthread_kill as not async-signal-safe
+- pthread_cancel was not async-cancel-safe
+- large-ulp errors in various math functions in non-default rounding modes
+
+arch-specific bugs fixed:
+- arm clock_gettime was broken on some hw due to bad time64 vdso
+- m68k sqrtl lacked long double precision
+- mips* syscall mechanism regressions on older kernels
+- mips* had negated error codes for some syscalls (kernel bug)
+- mips* SIGEMT was wrongly called SIGSTKFLT
+- sh fesetround didn't work correctly on sh
+
+
+
+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
