(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.

more bug fixes and program-compatibility improvements + +fixed floating point formatting and rounding bugs in printf. + +fixed broken %N$ positional argument specifiers in printf. + +fixed misaligned read/overread bug in strchr which could lead to +crashes scanning tiny strings at the end of a page when the next page +is not readable, or on archs (not yet supported) that forbid +misaligned reads. + +fixed breakage of statvfs on x86_64 + +fixed crash in getmntent_r + +fixed bug in POSIX timers created with NULL sigevent argument + +improved semaphore performance, and sem_wait is now interruptable by +signals, as required by POSIX. + +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
