0.9.13	9 August 2002

Security Fixes
    o   There was an off-by-one buffer overflow in the group 
	handling code, fix thanks to Joseph Chiu. 
    o   There was an integer overflow bug in calloc, per
	    http://online.securityfocus.com/bid/5398
    o   There was an integer overflow bug in the xdr_array 
	RPC code, per http://online.securityfocus.com/bid/5356

See Changelog.full for the complete list of who did what. 
Release highlights:
    o   Add full shared library support for Hitachi SuperH (sh)
	thanks to Stefan Allius and Edie C. Dost 
    o   Lots of reentrance cleanups (we should now be fully
	reentrant when compiled with pthread support).
    o   Miles Bader implemented a new mmap based malloc which is much
	smarter than the old "malloc-simple", and actually works, unlike
	the old "malloc".  This is now the default for mmu-less systems
	and should greatly help reduce memory fragmentation and wastage.
    o   Reworked syscall handling for i386 and ARM, smaller and cleaner.
    o   Support for the syscall() function on i386 and ARM
    o   The uClibc g++ wrapper now  automagically adds the proper include
	search path and and libraries.
    o   Lots of shared library loader updates
    o   dlopen'd shred libraries not properly run destructors
	when ctor/dtor support is enabled
    o   pread/pwrite/pread64/pwrite64 now all work as expected
    o   Lots and lots of other bug fixes and cleanups.

0.9.12	20 June 2002

See Changelog.full for the complete list of who did what. 
Release highlights:
    o   Add full shared library support for mips (big and little
	endian), thanks to a lot of hard work from Steven J. Hill
    o   i960 architecture support, thanks to Martin Proulx
    o   An initial alpha port (works, but needs some cleanup)
    o   Fixes shared library support for powerpc
    o   Fixes for mmu-less systems
    o   Much improved thread locking and reentrance.
    o   More gcc wrapper updates.  XFree86 really does link 
	this time around.  It still didn't last time.
    o   Libcrypt now passes conformance tests
    o   Nearly complete locale supporti thanks to a lot
	of hard work by Manuel Novoa III.  This stuff is
	_way_ smaller than glibc's
    o   Completely new time handling functions also by Manuel
    o   Lots of other bug fixes and cleanups.

Erik Andersen:
0.9.11	10 April 2002

Release highlights:
    o   Lots of bug fixes
    o   Much better large file support
    o   Several gcc wrapper bug fixes, so things like iproute2 and
	XFree86 should now link properly.
    o   Fixes a stdio thread locking bug that could cause random 
	deadlocks on s*printf calls when threading was enabled.

Erik Andersen:
    o   Added a generic implementation of truncate64.c and ftruncate64.c
    o   Added missing creat64, glob64, mkstemp64, getrlimit64, setrlimit64
    o   Removed internal erroneous use of __USE_FILE_OFFSET64
    o   Made libpthread compile on sparc and powerpc
    o   Made libpthread soname and symlinks match the other libraries.
    o   Added finite() to the C89 math lib, since some math functions use it.
    o   Added missing function pointer to error.c (some apps wanted it)
    o   Fixed initfini build for arches where gcc tries to be sneaky
    o   Fixed m68k/bits/setjmp.h which I has broken in the last release.
    o   Fixed a buffer overflow in the dynamic library loader
    o   Fixed a stdio thread locking bug that could cause random 
	deadlocks on s*printf calls when threading was enabled.
    o   Implemented sqrtf(), needed for libstdc++ on arm
Miles Bader:
    o   Make clean fixes to not blindly wipe all symlinks
    o   Re-enabled clnt_perror()
    o   Re-implemented swab()
Dwayne Fontenot:
    o   Many updates to the uClibc Working Application List 
Steven J. Hill:
    o   Many updates to the mips dynamic loader.  Not yet working but
	getting very close now.
    o   Fixed locking bug in getttyent()
    o   Support libpthread on mips
Richard June:
    o   Fixed several bugs in utmp code (pututline was only writing the 
	first sizeof-a-pointer bytes to the utmpfile).
    o   setutent() was only opening utmp readonly.
m4@brecis.COM:
    o   Fixed a silly typing problem with the getuid syscall.
Manuel Novoa III:
    o   Fixed stdio FILE read/write auto-transition bugs.
    o   Better stdio errno handling
    o   Changed setvbuf() to more closely match glibc's behavior
    o   Fixed getpass() to not echo passwords to the console
    o   Fixed locale ISblank flag.
    o   Fixed an arg promotion handling bug in _do_one_spec for %c reported
	by Ilguiz Latypov.
Kensuke Otake:
    o   Implemented swab()
Yoshinori Sato:
    o   Fixed h8300 architecture support for pthreads and changes to
	the include files
David Schleef:
    o   Made powerpc assembly code PIC-compatible
    o   Removed powerpc R_PPC_REL24 handling, since it was deceptively useless.
John Traill:
    o   Several types on powerpc, such as dev_t, are different than on other 
	architectures.  John spotted this, which fixed a _ton_ of problems since
	anything calling stat() was previously broken.
Jim Treadway:
    o   Eliminated use of alarm() from the DNS resolver by converting
	it to use select instead (much cleaner).








0.9.10	21 March 2002

Major new features:
    o   pthreads support (derived from glibc 2.1.3's linuxthreads library)
	    by Stefan Soucek and Erik Andersen

David Schleef:
    o   Debian packaging updates
    o   Check for proper 16-byte aliged stack pointer on powerpc

0.9.9	February  4, 2002

Erik Andersen:
    o   A bunch of doc updates.  Major update to the working
	apps list.
    o   Added a configurator script (extra/Configs/uClibc_config_fix.pl)

	conformance tests.
    o   Fixed sleep and usleep to work correctly when
	interrupted by signals.
    o   Made getopt behave the same when staticly linking
	as when dynamicly linking.  It was using different
	implementations depending on how apps were linked.
    o   Added missing inttypes.h header file
    o   Eliminate all C++ style comments from header files
    o   Support statvfs and statfs
    o   Support getmntent_r

    o   Fixed termios code to do the Right Thing(tm)
    o   Allow regex to be excluded at compile time
    o   Implemented mempcpy
    o   Build ldd and readelf for the target system and for the 
	host system
    o   Fix several cases where get-needed-libgcc-objects.sh
	could fail, breaking the shared uClibc library.
    o   Include all shared library loader objects into a
	single C file, thereby reducing its size further.
    o   Reworked the shared library linking process to be more 
	flexible so that gcc and ld can more easily be built to
	target uClibc library.
    o   Better error checking in the Makefiles.  Be more pedantic
	about tar, chmod, etc to avoid system dependent failures.
    o   We can now autodetect the target architecture
    o   Hide references to wchar_t so GNU autoconf
	configure scripts won't get confused and try to 
	enable wide char support. 
    o   Fixed stdio.h so apps can use varargs.h if they want to.
    o   Added brk/sbrk support for ARM, powerpc, mips, and sparc
	and set them to default to the much faster brk using malloc
    o   Added missing syscalls: get_kernel_syms, fcntl64,
	fdatasync, sched_setparam, sched_getparam,
	sched_setscheduler, sched_getscheduler,

	compile and work

	arch autodetection, etc.
    o   Fixed `make install' to not build ldso stuff on
	non-shared-library systems.

	working on an SH4 Dreamcast system.
Kim Heino:
    o   Made 'make clean' remove generated bits/syscall.h
David McCullough:
    o   SH architecture updates.  Added brk, sbrk,

    o   Taught getutent to return NULL if utmp doesn't exist. 
    o   Added insque/remque support

	on mmu-less systems
spudmonkey@racsa.co.cr:
