 added many compatibility and system-level interfaces, increasing the
 proportion of busybox that works with musl.

+
+
+0.7.8 - more bug fixes and compatibility improvements
+
+fixed problems with ipv6 dns and address printing code that made ipv6
+support practically unusable, and some other getaddrinfo bugs.
+
+fixed broken sendmsg/recvmsg functions on x86_64 (caused by incorrect
+msghdr structure).
+
+fixed broken sigsetjmp asm on x86_64.
+
+worked around a problem with input buffering on terminals reblocking
+after getting a blank line, due to a bug in the linux readv syscall.
+
+various improvements to the "rsyscall" system used to implement
+threaded setuid, setgid, etc.
+
+exiting/cancelling the a timer handler thread no longer kills the
+timer.
+
+fixed incorrect trailing zeros on some %g conversions in printf.
+
+fixed buggy byte-swapping functions and moved them to inlines in
+byteswap.h.
+
+many small improvements to header/application compatibility, support
+for nonstandard macros, etc.

+0.7.9 release notes
+
+new pthread cancellation implementation:
+- safe against resource-leak/side-effect-leak race conditions
+- safe against interruption by signal handlers
+- reduced bloat in all cancellable functions
+- reduced bloat for blocking cancellation
+
+new interfaces implemented:
+- realpath (limited functionality)
+- wordexp (limited functionality)
+- flock (nonstandard)
+- forkpty (nonstandard)
+- posix_fadvise
+- posix_fallocate
+
+general bug fixes:
+- syslog function failure to communicate with syslogd
+- bug in siginfo_t definition if wait.h was included before signal.h
+- incorrect struct definitions for most of sysv ipc
+- pthread_exit/cancel on timer handler wrongly destroying the timer
+- linux dup2 ebusy workaround
+- obscure issues in non-threaded programs using some pthread functions
+- getopt_long allowed mismatch in last char of option name
+- incorrect parsing of obscure ip address forms
+- initgroups not working reliably (uninitialized var)
+- shadow pass treating empty expiry field as pass-expired-in-1970
+- bogus longjmp if pthread_exit was called from cancellation handlers
+
+x86_64-specific bug fixes:
+- fcntl file locking
+- thread stack alignment
+- broken select timeouts due to incorrect timeval definition
+
+
+
+0.7.10 release notes
+
+new features:
+- ipv6 numeric string parsing
+- eventfd syscall wrappers
+
+optimizations:
+- new qsort implementation using the smoothsort algorithm
+- much smaller/faster sigset_t handling functions
+- lowered spin count before futex wait in synchronization functions
+
+general bug fixes:
+- incorrect floating point round-to-even behavior in printf
+- major bugs in pthread barrier implementation
+- off-by-one error in scanf %n results
+- scanf failure to report EOF when scanning for literal text
+- minor missing/incorrect prototype issues
+- dependency on undefined call order in fclose
+
+compiler issue workarounds:
+- incorrect inlining of variadic functions on recent gcc versions
+- pcc preprocessor bug with recursive macro expansion
+
+
+
+0.7.11 release notes
+
+new features:
+- integrated dynamic linker
+- dynamic loading (dlopen/dlsym) (for dynamic-linked programs only)
+- XSI search.h API
+- POSIX message queues
+- POSIX spawn interfaces
+- BSD pseudo-random number generator API (random/srandom/initstate/etc.)
+- floating point environment (limited usefulness due to gcc bugs)
+
+general bug fixes:
+- possible crashes with wordexp due to uninitialized variable
+- race condition in pthread_kill (also present and unfixed in glibc/nptl)
+- pthread exit destructors called too late
+- dangerous unbounded vla in glob
+- brk/sbrk legacy functions mismatching legacy semantics
+- wcsncpy dest buffer overflow
+- strncat and wcsncat possible overflows due to double-termination
+
+
+
+0.7.12 release notes
+
+new features:
+- support for textrels in shared objects
+- rpath support in dynamic linker
+- stdio_ext.h functions (for better gnu software compatibility)
+
+bug fixes:
+- some compilers miscompiling dlopen due to misuse of longjmp
+- safe handling of invalid long-double bit patterns (affects printf)
+- workaround for bugs in linux mprotect syscall
+- thread-safety for random() functions
+- various minor issues
