-Changes since the last public release (1.6.24):
- Reject oversized iCCP profile immediately.
- Cleaned up PNG_DEBUG compile of pngtest.c.
- Conditionally compile png_inflate().
- Don't install pngcp; it conflicts with pngcp in the pngtools package.
- Minor editing of INSTALL, (whitespace, added copyright line)
- Added MIPS support (Mandar Sahastrabuddhe <Mandar.Sahastrabuddhe@imgtec.com>).
- Rebased contrib/intel/intel_sse.patch after the MIPS implementation.
+Changes since the last public release (1.6.25):
+ 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 ").
