@@ -915,3 +915,140 @@ arch-specific bugs fixed:
 - various low-impact type size/alignment mismatches in some headers
 - epoll struct alignment wrong on non-x86[_64] archs
 - broken pipe2 fallback code on mips with old kernels

+
+0.9.11 release notes
+
+new features:
+- %m allocation modifier for scanf
+- week number and ISO week-based-year functionality in strftime
+- per-process and per-thread cputime clocks
+- ethernet address conversion interfaces
+- legacy classful ipv4 network address interfaces
+- minimal dlinfo function (nonstandard)
+
+other improvements:
+- dynamic linker path file can now use newlines to separate paths
+- math optimizations for archs with extended precision (i386)
+- musl-gcc wrapper now exposes gcc's intrinsic headers
+- quality of rand and rand_r pseudo-random sequences
+- support for large device minor numbers (greater than 8 bits)
+- various header conformance and compatibility fixes
+
+directly user-visible bugs fixed:
+- scanf losing characters on unbuffered streams and fmemopen streams
+- failure of mbsrtowcs to record stop position when dest is full
+- failure of iconv to convert to legacy codepages
+- non-working pthread_[sg]etschedparam functions (wrong syscall arguments)
+
+other potentially-serious bugs fixed:
+- resource leaks in sem_open
+- various bugs in thread exit synchronization
+- invalid access in aio notification after aiocb free/reuse
+- synchronization in dynamic linker when new thread dlopens during ctors
+- lack of error handling for failure to read dynamic linker path file
+- creation by mmap or shmget of objects larger than PTRDIFF_MAX
+
+minor conformance bugs fixed:
+- overflow handling for the clock function
+- workaround for incorrect exceptions in fma due to compiler bugs
+- workaround wrong kernel type for sem_nsems field in struct semid_ds
+
+arch-specific bugs fixed:
+- x86_64 sigsetjmp clobbered the signal mask rather than saving it
+- misaligned stack when calling ctors/dtors (crashing on x86_64)
+
+
+
+0.9.12 release notes
+
+new features:
+- zoneinfo time zone support
+- PIE support on all supported archs
+- named sub-archs for endian and float ABI variants
+- improved support for non-root installs of the dynamic linker
+- ability to selectively build only performance-critical modules with -O3
+- simple buffer overflow detection in free/realloc
+- inet_ntop now presents v4-mapped addresses in ::ffff:a.b.c.d form
+- ldd now reports libc and the dynamic linker in its output
+
+compatibility:
+- support for new init/fini array (needed for ctors/dtors on newer gcc)
+- C++ ABI fully matches glibc/LSB, at least on x86
+- many added ABI compatibility symbols for using glibc-linked libs
+- support for STB_GNU_UNIQUE symbol bindings (found in some C++ libs)
+- macros/types for new Linux kernel features in headers
+
+bugs fixed:
+- crashes in scanf on literal mismatches (regression from adding %m)
+- dl_iterate_phdr was passing invalid phdr pointers to its callback
+- getaddrinfo with null host and AF_UNSPEC was failing to report IPv6
+- integer overflows in date/time conversion code
+- misinterpretation of pre-1930s dates as post-2038 on 32-bit archs
+- make install failed to install bits headers if make was not run first
+- shm_open was wrongly cancellable
+- low- or no-impact heap corruption in memalign
+- explicitly running the dynamic linker on PIE programs did not work
+- missing macros and sysconf for some supported POSIX option groups
+- missing close-on-exec flags for several internal fd uses
+
+arch-specific bugs:
+- wrong SIG_ATOMIC_MIN/MAX macros on x86_64
+- erfcl was missing on archs where long double is same as double
+- broken dynamic-model TLS in static-linked arm/mips/powerpc programs
+
+
+
+0.9.13 release notes
+
+new features:
+- iconv support for EUC-KR and Big5 (including HKSCS) encodings
+- field widths (POSIX 2008 feature) in strftime
+- recursive rpath and $ORIGIN support in dynamic linker
+- cpu affinity interfaces
+- support for armhf (hardfloat) floating point environment (fenv)
+- support for SSE fenv on i386 (for apps using -mfpmath=sse -msse2)
+- strftime %s format (seconds since the epoch, future POSIX requirement)
+- configure script now saves its command line as a comment in config.mak
+- legacy functions valloc and euidaccess
+
+performance:
+- optimized asm memcpy for arm
+- optimized asm memset for i386 and x86_64
+- optimized C versions of memcpy and memset for all archs
+- eliminated major spurious syscalls from posix_spawn
+- some math asm for armhf (hardfloat)
+
+workarounds for:
+- qemu-user's rt_sigaction syscall does not allow old to alias new
+- qemu-user's madvise always succeeds (broke pthread_getattr_np)
+- passing PT_INTERP to dlopen attempted to double-load libc
+- gcc 4.8.x generating self-referential (infinite recursion) memcpy/memset
+- linux's lack of support for fchdir, fchmod, fchown, fstat on O_PATH fds
+
+bugs fixed:

+- SIGEV_THREAD timer id corruption and race condition issues
+- timer thread TLS incorrectly keeping values from previous expiry run
+- ecvt/fcvt decimal position off-by-one
+- in symbol-versioned libs, symbol resolved to oldest instead of newest
+- posix_spawn not correctly reporting errno from exec failure
+- "make install" was not atomic (overwrote files rather than replacing)
+- integer overflows in strftime
+- unset/empty TZ variable was mishandled
+- strftime could crash if the struct tm did not have valid tm_zone field
