+- aarch64 port (experimental)
+
+performance:

+- always set optarg in getopt_long
+- support SOCK_RAW socket type in getaddrinfo
+- report success instead of EINPROGRESS when close is interrupted
+
+bugs fixed:
+- multithreaded set*id() was not async-signal safe, had various race bugs
+- getspnam_r returned results for partial username matches
+- wordexp bad character checker mis-counted parentheses
+- close on fd with pending aio could lead to file corruption
+- old aio implementation had numerous conformance bugs
+- malloc init code could deadlock due to race condition
+- pthread_exit did not disable cancellation
+- pthread_cond_wait could wrongly consume signal on cancellation
+- execvp wrongly stopped path search on EACCESS
+- fsync, fdatasync, and msync were not honored as cancellation points
+- fchmodat was subject to fd leak race (missing O_CLOEXEC)
+- fchmodat failed to report EOPNOTSUPP in race path
+- passwd/group lookup functions had various minor error-reporting bugs
+- isatty had false-positives/device-state-corruption for OSS sound devices
+- configure script failed to detect gcc with translated messages
+- FLT_ROUNDS macro failed to reflect rounding mode changes in fenv
+
+arch-specific bugs fixed:
+- mips fesetenv did not handle FE_DFL_ENV
+- mips POLLWRNORM and POLLWRBAND macros had wrong values
+- x32 pthread synchronization object type definitions were wrong
+- powerpc minimum signal stack size was insufficient
+
+
+
+1.1.8 release notes
+
+bugs fixed:
+- stack-based buffer overflow in inet_pton (CVE-2015-1817)
+- regcomp crash/mem-corruption with illegal bytes after backslash
+- regcomp wrongly allowed backrefs in ER
+- regcomp miscompiled character class brace-repetitions
+- regcomp wrongly processed \0 as an unmatchable backref
+- new FLT_ROUNDS definition failed to work in C++ code
+
+arch-specific bugs fixed:
+- aarch64 was missing max_align_t definition
+
+
+
+1.1.9 release notes
+
+new features:
+- ability to protect libc code itself with stack protector
+- sigsetjmp now restores signal mask after restoring context, not before
+- thread-local dlerror status/messages
+- dlerror messages are no longer truncated
+- diagnostics for constraint violations with ctype.h macros
+
+optimizations:
+- reduce cost of PIC on archs where PLT calls need a fixed GOT register
+- spin locks no longer constantly invalidate cache lines while spinning
+- code size reduction in static-linked TLS init
+
+bugs fixed:
+- failure to process robust mutexes on detached-thread exit
+- possible memory corruption due to robust mutex list on detached-thread exit
+- crash on memory exhaustion in getgr* internals
+- misaligned memory accesses in static binaries with low-alignment TLS blocks
+- multiple cases of wrongful path search continuation after transient failure
+- small memory leak on failure of dlopen with RPATH $ORIGIN
+- several small math bugs related to exception flags with non-finite args
+- mmap leak in sem_open failure path for link call
+- duplocale clobbered new locale struct with memcpy of old
+- futimes crashed with null timeval argument
+
+arch-specific bugs fixed:
+- stack protector spuriously aborted after forking on x32
+- stack protector spuriously aborted with flockfile on powerpc
+- theoretically-possible clobbering of syscall return value on mips
+- random thread-pointer setup failure on sh (uninitialized return value)
+- possible crash in dlsym on sh due to incorrectly-computed branch target
+- broken fesetenv(FE_DFL_ENV) on mips
+- dynamic linker name for sh ignored fpu/nofpu and endianness
+- various minor aarch64 bugs
+- dangling pointers in x32 syscall timespec fixup code
