Libpng 1.2.8 - December 3, 2004
Libpng 1.2.9beta1 - February 21, 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 (1.2.7):
Changes since the last public release (1.2.8):
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().
Added PNG_1_2_X definition in pngconf.h
#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).
version 1.2.9beta1 [February 21, 2006]
Initialized some structure members in pngwutil.c to avoid gcc-4.0.0 complaints
Revised man page and libpng.txt to make it clear that one should not call
png_read_end or png_write_end after png_read_png or png_write_png.
Updated references to png-mng-implement mailing list.
Fixed an incorrect typecast in pngrutil.c
Added PNG_READ_SUPPORTED conditionals for making a write-only library.
Added PNG_NO_WRITE_INTERLACING_SUPPORTED conditional.
Optimized alpha-inversion loops in pngwtran.c
Moved test for nonzero gamma outside of png_build_gamma_table() in pngrtran.c
Make sure num_trans is <= 256 before copying data in png_set_tRNS().
Make sure num_palette is <= 256 before copying data in png_set_PLTE().
Interchanged order of write_swap_alpha and write_invert_alpha transforms.
Added parentheses in the definition of PNG_LIBPNG_BUILD_TYPE (Cosmin).
Optimized zlib window flag (CINFO) in contrib/pngsuite/*.png (Cosmin).
Updated scripts/makefile.bc32 for Borland C++ 5.6 (Cosmin).
Fixed inconsistency in definition of png_default_read_data()
Exported png_get_uint_32, png_save_uint_32, png_get_uint_16, png_save_uint_16,
png_get_int_32, png_save_int_32, png_get_uint_31 (Cosmin).
Added parentheses in the definition of PNG_LIBPNG_BUILD_TYPE (Cosmin).
Updated scripts/pngos2.def, scripts/pngw32.def (Cosmin).
Added type cast (png_byte) in png_write_sCAL() (Cosmin).
Fixed scripts/makefile.cygwin (Cosmin).

Using the ./configure script -- 16 December 2002.
=================================================
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 \

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 1.2.8 are Y2K compliant. It is my belief that earlier
upward through 1.2.9beta1 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.
