-fixed printf %n specifier (again).
+fixed printf %n specifier (again), pthread_once (it was always
+hanging), and non-default-type mutex behavior.
 
 added ucontext/sigcontext support in headers to facilitate building
 libgcc with dwarf2 unwind support, and possibly other low-level tools.
 
+improved musl-gcc compiler wrapper.
+
 implemented many small missing functions here and there, minor header
 fixes, etc.

+
+0.7.1 - improvements to completeness, bug fixes
+
+implemented flockfile, wprintf, and robust mutex functions.
+
+fixed stack corruption bug in times(), minor header bugs, and some
+error return value bugs in thread interfaces.
+
+
+
+0.7.5 - new features, major optimization, and robustness
+
+implemented POSIX timers.
+
+optimized and simplified many thread-related functions.
+
+eliminated resource leak races in thread cancellation. (almost all
+existing implementations, including glibc, have these leaks.)
+
+overhauled stdio implementation to take advantage of readv/writev for
+reduced syscall load, and improved stdio's handling of error status.
+
+added syscall header and interface for applications to use and
+greatly simplified internal system for making syscalls.
+
+strangthened tmpnam/tempnam/tmpfile filename generation and made the
+straight C functions not depend on POSIX symbols.
+
+fixed pthread cancellation ABI on i386 to match the LSB/glibc ABI
+
+better double-free handling in malloc
+
+various minor bug fixes
+
+
+
+0.7.6 - major bug fixes
+
+fixed rare but serious under-allocation bug in malloc.
+
+fixed signedness bug in strchr that prevented finding high bytes.
+
+fixed serious parsing bugs in strtold.
+
+fixed statvfs syscall (it was always failing with EINVAL).
+
+fixed race condition in set*id() functions with threads (possible
+deadlock). further audit still needed though.
+
+fseek no longer sets the stream error flag on failed seeks (this was
+wrong and broke some programs, notably GNU m4).
+
+nl_langinfo is no longer a dummy function. (the functionality was
+previously implemented but accidentally left unused).
+
+various small fixes have been made to the implementations and
+prototypes for nonstandard and obsolete functions
