Changes since the last public release (1.6.25):
Changes since the last public release (1.6.26):
Fixed handling zero length IDAT in pngfix (bug report by Agostino Sarubbo,
bugfix by John Bowler).
Do not issue a png_error() on read in png_set_pCAL() because png_handle_pCAL
has allocated memory that libpng needs to free.
Conditionally compile png_set_benign_errors() in pngread.c and pngtest.c
Issue a png_benign_error instead of a png_error on ADLER32 mismatch
while decoding compressed data chunks.
Changed PNG_ZLIB_VERNUM to ZLIB_VERNUM in pngpriv.h, pngstruct.h, and
pngrutil.c.
If CRC handling of critical chunks has been set to PNG_CRC_QUIET_USE,
ignore the ADLER32 checksum in the IDAT chunk as well as the chunk CRCs.
Issue png_benign_error() on ADLER32 checksum mismatch instead of png_error().
Add tests/badcrc.png and tests/badadler.png to tests/pngtest.
Merged pngtest.c with libpng-1.7.0beta84/pngtest.c
Updated the documentation about CRC and ADLER32 handling.
Quieted 117 warnings from clang-3.8 in pngtrans.c, pngread.c,
pngwrite.c, pngunknown.c, and pngvalid.c.
Quieted the 144 remaining -Wconversion compiler warnings by
revising the png_isaligned() macro and trivial changes in png.c,
pngerror.c, pngget.c, pngmem.c, pngset.c, pngrtran.c, pngrutil.c,
pngwtran.c, pngwrite.c, and pngwutil.c.
Quieted (bogus?) clang warnings about "absolute value has no effect"
when PNG_USE_ABS is defined.
Fixed offsets in contrib/intel/intel_sse.patch
Changed integer constant 4294967294 to unsigned 4294967294U in pngconf.h
to avoid a signed/unsigned compare in the preprocessor.
Use zlib-1.2.8.1 inflateValidate() instead of inflateReset2() to
optionally avoid ADLER32 evaluation.
Cosmetic change, "ptr != 0" to "ptr != NULL" in png.c and pngrutil.c
Despammed email addresses (replaced "@" with " at ").
