Libpng 1.0.18 - December 3, 2004
Libpng 1.0.19rc1 - June 13, 2006
This is a public release of libpng, intended for use in production codes.
This is not intended to be a public release. It will be replaced
within a few weeks by a public version or by another test version.
Changes since the last public release (1.0.17):
Files available for download:
Fixed bug in png_text_compress() that would fail to complete a large block.
Fixed bug, introduced in libpng-1.2.7, that overruns a buffer during
strip alpha operation in png_do_strip_filler().
#ifdef out png_info_init in png.c and png_read_init in pngread.c (as of 1.3.0)
Reduce color_type to a nonalpha type after strip alpha operation in
png_do_strip_filler().
Revised definitions of PNG_MAX_UINT_32, PNG_MAX_SIZE, and PNG_MAXSUM
Fixed (again) definition of PNG_LIBPNG_VER_DLLNUM in png.h (Cosmin).
Added PNG_LIBPNG_BUILD_PRIVATE in png.h (Cosmin).
Set png_ptr->zstream.data_type to Z_BINARY, to avoid unnecessary detection
of data type in deflate (Cosmin).
Deprecated but continue to support SPECIALBUILD and PRIVATEBUILD in favor of
PNG_LIBPNG_BUILD_SPECIAL_STRING and PNG_LIBPNG_BUILD_PRIVATE_STRING.
Despammed mailing addresses by masking "@" with "at".
Added scripts/makefile.elf with supporting code in pngconf.h for symbol
versioning (John Bowler).
Added projects/visualc71 (Simon-pierre).

"configure" script

version 1.2.11beta1 [May 31, 2006]
scripts/libpng.pc.in contained "configure" style version info and would
not work with makefiles.
The shared-library makefiles were linking to libpng.so.0 instead of
libpng.so.3 compatibility as the library.
version 1.2.11beta2 [June 2, 2006]
Increased sprintf buffer from 50 to 52 chars in pngrutil.c to avoid
buffer overflow.
Fixed bug in example.c (png_set_palette_rgb -> png_set_palette_to_rgb)
version 1.2.11beta3 [June 5, 2006]
Prepended "#! /bin/sh" to ltmail.sh and contrib/pngminus/*.sh (Cosmin).
Removed the accidental leftover Makefile.in~ (Cosmin).
Avoided potential buffer overflow and optimized buffer in
png_write_sCAL(), png_write_sCAL_s() (Cosmin).
Removed the include directories and libraries from CFLAGS and LDFLAGS
in scripts/makefile.gcc (Nelson A. de Oliveira, Cosmin).
version 1.2.11beta4 [June 6, 2006]
Allow zero-length IDAT chunks after the entire zlib datastream, but not
after another intervening chunk type.
version 1.2.11rc1 [June 13, 2006]
Deleted extraneous square brackets from [config.h] in configure.ac

=================================================
The ./configure script should work compatibly with what scripts/makefile.*
did, however there are some options you need to add to configure explicitly,
which previously was done semi-automatically (if you didn't edit
scripts/makefile.* yourself, that is)
CFLAGS="-Wall -O3 -funroll-loops \

/usr/include/png12, or whatever.

Y2K compliance in libpng:
=========================
December 3, 2004
June 13, 2006
Since the PNG Development group is an ad-hoc body, we can't make
an official declaration.
This is your unofficial assurance that libpng from version 0.71 and
upward through 1.0.18 are Y2K compliant. It is my belief that earlier
upward through 1.0.19rc1 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.
Libpng only has three year fields. One is a 2-byte unsigned integer

pnmtopng / pngtopnm utilities. Independantly Alexander Lehmann and I
(Willem van Schaik) started such a project. Luckily we discovered this

## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the `deleted header file' problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
