Changes since the last public release (1.6.25):
|
|
|
|
Version 1.6.26beta01 [September 26, 2016]
|
|
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
|
|
|
|
Version 1.6.26beta02 [October 1, 2016]
|
|
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 58 (out of 144) -Wconversion compiler warnings by changing
|
|
flag definitions in pngpriv.h from 0xnnnn to 0xnnnnU and trivial changes
|
|
in png.c, pngread.c, and pngwutil.c.
|
|
|
|
Version 1.6.26beta03 [October 2, 2016]
|
|
Removed contrib/libtests/*.orig and *.rej that slipped into the tarballs.
|
|
Quieted the 86 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.
|
|
|
|
Version 1.6.26beta04 [October 3, 2016]
|
|
Quieted (bogus?) clang warnings about "absolute value has no effect"
|
|
when PNG_USE_ABS is defined.
|
|
Fixed offsets in contrib/intel/intel_sse.patch
|
|
|
|
Version 1.6.26beta05 [October 6, 2016]
|
|
Changed integer constant 4294967294 to unsigned 4294967294U in pngconf.h
|
|
to avoid a signed/unsigned compare in the preprocessor.
|
|
|
|
Version 1.6.26beta05 [October 7, 2016]
|
|
Use zlib-1.2.8.1 inflateValidate() instead of inflateReset2() to
|
|
avoid ADLER32 evaluation.
