| 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. |
