+1.2.3 release notes
+
+new features:
+- qsort_r function (POSIX-future)
+- pthread_getname_np extension function
+- hard float on SPE FPU for powerpc-sf
+- SEEK_DATA and SEEK_HOLE exposed in unistd.h (Linux extensions)
+
+compatibility:
+- free now preserves errno (POSIX-future requirement)
+- setjmp is declared explicitly with returns_twice for non-GCC compilers
+- macro version of isascii is no longer defined for C++
+- dynamic linker now tolerates zero-length LOAD segments
+- epoll_[p]wait is now a cancellation point
+- pwd/grp functions no longer fail on systems without AF_UNIX support
+- POSIX TZ parsing is stricter to allow more names to fallback to files
+- NULL is now defined as nullptr when used in C++11 or later
+- gettext now accepts null pointer as argument
+
+bugs fixed:
+- old regression in wcwidth of Hangul combining (vowel/final) letters
+- duplocale used wrong malloc when malloc was replaced (1.2.2 regression)
+- fmaf rounded wrong on archs without FE_TOWARDZERO (all softfloat archs)
+- popen didn't honor requirement not to leak other popen pipe fds to child
+- aligned_alloc and variants crashed on allocation failure
+- dl_iterate_phdr reported incorrect module TLS pointers
+- mishandling of some inputs in acoshf and expm1f and functions using them
+- potentially wrong-sign zero in cproj functions at infinity
+- multiple bugs in legacy function cuserid
+- minor posix_spawn file actions API conformance issues
+- pthread_setname_np fd leak
+- out-of-bound read in zoneinfo handling with distant-past times
+- out-of-tree builds lacked generated debug cfi for x86 asm
+
+arch-specific bugs fixed:
+- powerpc (32-bit) struct shmid_ds layout was wrong for some fields
+- time64 struct layout was wrong in sound ioctl fallback (32-bit archs)
+

+
+1.2.4 release notes
+
+new features:
+- large dns record lookups via tcp fallback
+- new getaddrinfo EAI_NODATA result to distinguish NODATA/NxDomain
+- support for new RELR compressed format for relative relocations
+- sysconf keys for querying signal stack size requirements
+- real vfork on riscv64
+
+performance:
+- mallocng no longer uses MADV_FREE (high performance cost, little gain)
+- vdso clock_gettime is supported once again on 32-bit arm
+
+compatibility:
+- gethostbyname family now distinguishes NO_DATA from HOST_NOT_FOUND
+- res_send now works with caller-provided edns0 queries
+- arpa/nameser.h RR types list is now up-to-date
+- previously-missing POSIX confstr keys have been added
+- mntent interfaces now accept missing fields

+- pthread_atfork now admits calls from an application-provided malloc
+- debugger tracking of shared libraries now works on MIPS PIE binaries
+- sendmsg now supports up to SCM_MAX_FD fds in SCM_RIGHTS messages
+
+bugs fixed:
+- gethostbyname[2]_r wrongly returned nonzero (error) on negative result
+- parallel v4/v6 address queries could fail on query id collisions
+- spurious getaddrinfo/AI_ADDRCONFIG failures due to errno clobbering
+- dns search domains ending in dot (including lone dot) broke lookups
+- ipv6 servers in resolv.conf broke lookups on systems with v6 disabled
+- systems with bindv6only failed to query both v4 and v6 nameservers
+- res_mkquery mishandled consecutive final dots in name
+- res_send could malfunction for very small answer buffer sizes
+- resolver dns backend accepted answers with wrong (A vs AAAA) RR type
+- getservbyport_r returned junk or ENOENT (vs ERANGE) on buffer size errors
