-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 ").

+Changes since the last public release (1.6.26):
+ Control ADLER32 checking with new PNG_IGNORE_ADLER32 option.
+ Removed the use of a macro containing the pre-processor 'defined'
+ operator. It is unclear whether this is valid; a macro that
+ "generates" 'defined' is not permitted, but the use of the word
+ "generates" within the C90 standard seems to imply more than simple
+ substitution of an expression itself containing a well-formed defined
+ operation.
+ Added ARM support to CMakeLists.txt (Andreas Franek).
+ Fixed a potential null pointer dereference in png_set_text_2() (bug report
+ and patch by Patrick Keshishian).
