build system:
- only use expensive -ffloat-store cflag on archs/compilers that need it
- make musl-gcc wrapper support -lgcc (mainly for self-hosting)

+performance:
+- assembly (string ops based) memcpy for i386 and x86_64
+- reduce printf overhead
+
+bug fixes:
+- failure of strtod, etc. to process extremely long strings correctly
+- read overrun in wcsstr for short needles
+- various major mips issues that prevented most software from working
+- erroneous floating point exception behavior in i386/x86_64 exp asm
+- crashes on null arguments to legacy err.h functions
+- various header file/type issues
+- extremely rare/obscure race condition with robust mutexes
+- crypt now never returns null (most programs don't check, then crash)
+- missing xattr remove functions
+
+
+
+0.9.5 release notes
+
+compatibility and headers:
+- POSIX+XSI+BSD features enabled by default with no macros defined
+- most programs can now be built without adding -D_GNU_SOURCE

+- support for compiling musl with clang/llvm
+
+new features:
+- sha 256/512 password hash functions in crypt
+- GNU hash support in dynamic linker
+- partial C11 coverage
+- dladdr function added
+- dynamic linker reports all errors instead of exiting on first error
+- syscall wrappers added for most remaining linux syscalls
+- provide POSIX O_SEARCH open mode using linux O_PATH
+
+bug fixes:
+- most atexit functions were being skipped when exiting
+- some BSD functions were not being exposed under _BSD_SOURCE
+- issues loading ssp-protected DSO into non-ssp program with dlopen
+
+debloating:
+- eliminate .eh_frame (10-15% loaded size bloat)
+- optimal inline syscall asm for ARM and MIPS
+- no longer force -O3 for shared libs
+
+
+
+0.9.6 release notes
+
+bug fixes:
+- serious breakage in definition of O_ACCMODE mask (missing a bit)
+
+new features:
+- O_EXEC open mode
+- md5 crypt hash function
+
+
+
+0.9.7 release notes
+
+new features:
+- thread-local storage (__thread/_Thread_local)
+- microblaze port
+- getopt option parsing reset support
+- vsyscall (sysenter, etc.) support on i386 (faster syscalls)
+- memmem function (GNU extension)
+- mips fenv support
+- accept "nan(n-char-sequence)" in strtod/scanf family functions
+- configure now supports compiling with pcc
+
+quality and correctness improvements:
+- close-on-exec flag for all library-internal file descriptors
+- cancellation-safety and corner-case overhaul in shm_open/sem_open
+- close EINTR vs EINPROGRESS issue
+- mark binaries as not requiring executable stack
+- better gdb compatibility in dynamic linker
+- support recursive dlopen (dlopen called from constructors)
+- posix_spawn/system/popen no longer momentarily double commit charge
+- all stdio functions wait for locks
+
+bug fixes:
+- broken sysvipc *ctl functions on 64-bit archs
+- broken shmdt on some archs
+- getaddrinfo failure with port "0"
+- dirname handling of trailing slash
+- vfork race in posix_spawn
+
+
+
+0.9.8 release notes
+
+new features:
+- powerpc port
+- dl_iterate_phdr interface
+- added mips-specific syscalls
+- thread priority scheduling
+- C11 CMPLX macro in complex.h
+- x86 port io functions in sys/io.h
+
+compatibility:
+- improved headers for trace/debugging/machine-access
+- stub functions for unsupported thread-related functionality
+
+bug fixes:
+- numerous math bugs (mostly exception flags and excess-precision issues)
+- register clobber error in i386 vsyscall asm (did not affect most callers)
+- various incorrect definitions in mips headers
+- broken dlsym asm on mips
+- empty prefix handling in configure script (--prefix="")
+- ldso search path logic issues
+- lock handling for stdio memory streams at exit time
+- invalid SO_REUSEPORT definition in socket.h (not supported by Linux)
+- broken redirection attempt to /dev/null in configure script
