- 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.
+ Revised comments in png_set_read_fn() and png_set_write_fn().
+ Revised order of #ifdef's and indentation in png_debug definitions of png.h
+ bug introduced in libpng-1.2.34.
+ Use png_memset() after png_malloc() of big_row_buf when reading an
+ interlaced file, to avoid a possible UMR.
+ Undid recent revision of PNG_NO_STDIO version of png_write_flush(). Users
+ having trouble with fflush() can build with PNG_NO_WRITE_FLUSH defined.
+ Revised libpng*.txt documentation about use of png_write_flush().
+ Removed fflush() from pngtest.c.
+ Added "#define PNG_NO_WRITE_FLUSH" to contrib/pngminim/encoder/pngusr.h
+ Relocated misplaced PNG_1_0_X define in png.h that caused the prototype
+ for png_set_strip_error_numbers() to be omitted from PNG_NO_ASSEMBLER_CODE
+ 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
+ Fixed potential memory leak of "new_name" in png_write_iCCP() (Ralph Giles)
+ Added "ifndef PNG_SKIP_SETJMP_CHECK" block in pngconf.h to allow
+ application code writers to bypass the check for multiple inclusion
+ of setjmp.h when they know that it is safe to ignore the situation.
+ 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.

Since the PNG Development group is an ad-hoc body, we can't make

This is your unofficial assurance that libpng from version 0.71 and
