version 1.2.35 [February 14, 2009]
version 1.2.40 [September 10, 2009]

Zero out all arrays of pointers after png_malloc(). (Tavis Ormandy)
Use png_memset() instead of a loop to intialize pointers. We realize
this will not work on platforms where the NULL pointer is not all zeroes.
Removed an extra png_debug() recently added to png_write_find_filter().
Fixed incorrect #ifdef in pngset.c regarding unknown chunk support.
Various bugfixes and improvements to CMakeLists.txt (Philip Lowman)

Use png_memset() after png_malloc() of big_row_buf when reading an

builds. This bug was introduced in libpng-1.2.15beta4.
Added a section on differences between 1.0.x and 1.2.x to libpng.3/libpng.txt

of setjmp.h when they know that it is safe to ignore the situation.
Made some cosmetic changes to whitespace in pngtest output.
Renamed "user_chunk_data" to "my_user_chunk_data" in pngtest.c to suppress
"shadowed declaration" warning from gcc-4.3.3.
Renamed "gamma" to "png_gamma" in pngset.c to avoid "shadowed declaration"
warning about a global "gamma" variable in math.h on some platforms.

version 1.2.37beta01 [May 14, 2009]
Fixed inconsistency in pngrutil.c, introduced in libpng-1.2.36. The
memset() was using "png_ptr->rowbytes" instead of "row_bytes", which
the corresponding png_malloc() uses (Joe Drew).
Clarified usage of sig_bit versus sig_bit_p in example.c (Vincent Torri)
Updated some of the makefiles in the scripts directory (merged with
those in libpng-1.4.0beta57).

version 1.2.37beta02 [May 19, 2009]
Fixed typo in libpng documentation (FILTER_AVE should be FILTER_AVG)
Relocated misplaced #endif in pngwrite.c, sCAL chunk handler.
Conditionally compile png_read_finish_row() which is not used by
progressive readers.

decoder, based on contrib/gregbook with embedded libpng and zlib.

is only one makefile in those directories, and revised the README files
accordingly.

Reformatted several remaining "else statement;" and "if () statement;" into
two lines.
Added "#define PNG_NO_WRITE_SWAP" to contrib/pngminim/encoder/pngusr.h
and "define PNG_NO_READ_SWAP" to decoder/pngusr.h and preader/pngusr.h
Added sections about the git repository and our coding style to the
documentation (merged from libpng-1.4.0beta62)
Added a section to the libpng documentation about using png_get_io_ptr()
in configure scripts to detect the presence of libpng.

version 1.2.38beta01 [June 17, 2009]
Revised libpng*.txt and libpng.3 to mention calling png_set_IHDR()
multiple times and to specify the sample order in the tRNS chunk,
because the ISO PNG specification has a typo in the tRNS table.
Changed several PNG_UNKNOWN_CHUNK_SUPPORTED to
PNG_HANDLE_AS_UNKNOWN_SUPPORTED, to make the png_set_keep mechanism
available for ignoring known chunks even when not saving unknown chunks.
Adopted preference for consistent use of "#ifdef" and "#ifndef" versus
"#if defined()" and "if !defined()" where possible.
Added PNG_NO_HANDLE_AS_UNKNOWN in the PNG_LEGACY_SUPPORTED block of
pngconf.h, and moved the various unknown chunk macro definitions
outside of the PNG_READ|WRITE_ANCILLARY_CHUNK_SUPPORTED blocks.
