Changes since the last public release (1.0.52): Changes since the last public release (1.0.53):
version 1.0.53 [February 25, 2010] version 1.0.54 [July 2, 2010]
Rewrote png_process_IDAT_data to consistently treat extra data as warnings
and handle end conditions more cleanly.
Removed the now-redundant check for out-of-bounds new_row from example.c
Updated CMakeLists.txt for consistent indentation and to avoid an
unclosed if-statement warning (Philip Lowman).
Removed "#ifdef PNG_1_0_X / #endif" surrounding
PNG_READ_16_TO_8_SUPPORTED and PNG_READ_GRAY_TO_RGB_SUPPORTED
in pngconf.h. These were added in libpng-1.2.41beta08 and libpng-1.0.51,
which introduced a binary incompatibility with libpng-1.0.50.
Backported two-pass png_decompress_chunk() algorithm from libpng-1.4.1
Removed PNGAPI declaration of png_calloc() and png_write_sig() in
1ibpng-1.2.X, introduced by mistake in libpng-1.2.41.
Return allocated "old_buffer" in png_push_save_buffer() before png_error(),
to avoid a potential memory leak.
Ported rewritten png_decompress_chunk() by John Bowler from libpng-1.4.1.
Define _ALL_SOURCE in configure.ac, makefile.aix, and CMakeLists.txt
when using AIX compiler.
Removed unused gzio.c from contrib/pngminim gather and makefile scripts
