 fixed a major bug in the printf %n specifier that prevented it from
 working and caused memory corruption.

+0.7.0 - major improvements to posix conformance and completeness
+
+implemented posix shared memory and semaphore interfaces.
+
+implemented all remaining required pthread and clock interfaces.
+
+major fixes to signal semantics.
+
+greatly improved temporary file name generation for safety against
+denial of service due to intentional name collisions.
+
+added syscall wrappers for the linux inotify interface.
+
+malloc(0) now returns a non-null pointer.
+
+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

+
+
+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
