Libpng 1.2.2rc1 - April 7, 2002
Libpng 1.2.2 - April 15, 2002
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.
This is a public release of libpng, intended for use in production codes.
Changes since the last public release (1.2.1):
version 1.2.2beta1 [February 22, 2002]
Fixed a bug with reading the length of iCCP profiles (Larry Reeves).
Revised makefile.linux, makefile.gcmmx, and others to generate
libpng.a, libpngNN.so (not libpng.so.3), and libpngNN/png.h
libpng.a, libpngNN.so, libpng.so.NN, and libpngNN/png.h
Revised makefile.darwin to remove "-undefined suppress" option.
Added checks for gamma and chromaticity values over 21474.83, which exceed
the limit for PNG unsigned 32-bit integers when encoded.
Revised calls to png_create_read_struct() and png_create_write_struct()
for simpler debugging.
Revised png_zalloc() so zlib handles errors (uses PNG_FLAG_MALLOC_NULL_MEM_OK)
version 1.2.2beta2 [February 23, 2002]
Check chunk_length and idat_size for invalid (over PNG_MAX_UINT) lengths.
Check for invalid image dimensions in png_get_IHDR.
Added missing "fi;" in the install target of the SGI makefiles.
Added install-static to all makefiles that make shared libraries.
Added install-shared and install-static targets to all makefiles that make
shared libraries.
Always do gamma compensation when image is partially transparent.
version 1.2.2beta3 [March 7, 2002]
Modified shared-library makefiles to install pkgconfig/libpngNN.pc.
Export (with PNGAPI) png_zalloc, png_zfree, and png_handle_as_unknown
Removed unused png_write_destroy_info prototype from png.h
Eliminated incorrect use of width_mmx from pnggccrd.c in pixel_bytes == 8 case
Added install-shared target to all makefiles that make shared libraries.
Stopped a double free of palette, hist, and trans when not using free_me.
Added makefile.32sunu for Sun Ultra 32 and makefile.64sunu for Sun Ultra 64.
version 1.2.2beta4 [March 8, 2002]
Compute background.gray and background_1.gray even when color_type is RGB
in case image gets reduced to gray later (Jason Summers).
Relocated a misplaced /bin/rm in the "install-shared" makefile targets
Added PNG_1_0_X macro which can be used to build a 1.0.x-compatible library.
version 1.2.2beta5 [March 26, 2002]
Added missing PNGAPI to several function definitions.
Check for invalid bit_depth or color_type in png_get_IHDR(), and
check for missing PLTE or IHDR in png_push_read_chunk() (Matthias Clasen).
Revised iTXt support to accept NULL for lang and lang_key.
Compute gamma for color components of background even when color_type is gray.
Changed "()" to "{}" in pkgconfig/libpngNN.pc.
Revised makefiles to put png.h and pngconf.h only in $prefix/include/libpngNN
Revised makefiles to make symlink to libpng.so.NN in addition to libpngNN.so
version 1.2.2beta6 [March 31, 2002]
version 1.0.13beta1 [March 31, 2002]
Prevent png_zalloc() from trying to memset memory that it failed to acquire.
Add typecasts of PNG_MAX_UINT in pngset_cHRM_fixed() (Matt Holgate).
Ensure that the right function (user or default) is used to free the
png_struct after an error in png_create_read_struct_2().
version 1.2.2rc1 [April 7, 2002]
Save the ebx register in pnggccrd.c (Sami Farin)
Add "mem_ptr = png_ptr->mem_ptr" in png_destroy_write_struct() (Paul Gardner).
Updated makefiles to put headers in include/libpng and remove old include/*.h.
Revised description of png_set_filter() in libpng.3/libpng.txt.
Revised makefile.netbsd and added makefile.neNNbsd and makefile.freebsd

* April 15, 2002
*
* 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 1.2.2rc1 are Y2K compliant. It is my belief that earlier
* upward through 1.2.2 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
