Do not call + memcpy() with a null source, even if count is zero (Leon Scroggins III). + +Version 1.6.23 [June 9, 2016] + Fixed bad link to RFC2083 in png.5 (Nikola Forro). + +Version 1.6.24beta01 [June 11, 2016] + Avoid potential overflow of the PNG_IMAGE_SIZE macro. This macro + is not used within libpng, but is used in some of the examples. + +Version 1.6.24beta02 [June 23, 2016] + Correct filter heuristic overflow handling. This was broken when the + write filter code was moved out-of-line; if there is a single filter and + the heuristic sum overflows the calculation of the filtered line is not + completed. In versions prior to 1.6 the code was duplicated in-line + and the check not performed, so the filter operation completed; however, + in the multi-filter case where the sum is performed the 'none' filter would + be selected if all the sums overflowed, even if it wasn't in the filter + list. The fix to the first problem is simply to provide PNG_SIZE_MAX as + the current lmins sum value; this means the sum can never exceed it and + overflows silently. A reasonable compiler that does choose to inline + the code will simply eliminate the sum check. + The fix to the second problem is to use high precision arithmetic (this is + implemented in 1.7), however a simple safe fix here is to chose the lowest + numbered filter in the list from png_set_filter (this only works if the + first problem is also fixed) (John Bowler). + Use a more efficient absolute value calculation on SSE2 (Matthieu Darbois). + Fixed the case where PNG_IMAGE_BUFFER_SIZE can overflow in the application + as a result of the application using an increased 'row_stride'; previously + png_image_finish_read only checked for overflow on the base calculation of + components. (I.e. it checked for overflow of a 32-bit number on the total + number of pixel components in the output format, not the possibly padded row + length and not the number of bytes, which for linear formats is twice the + number of components.) + MSVC does not like '-(unsigned)', so replaced it with 0U-(unsigned) + MSVC does not like (uInt) = -(unsigned) (i.e. as an initializer), unless + the conversion is explicitly invoked by a cast. + Put the SKIP definition in the correct place. It needs to come after the + png.h include (see all the other .c files in contrib/libtests) because it + depends on PNG_LIBPNG_VER. + Removed the three compile warning options from the individual project + files into the zlib.props globals. It increases the warning level from 4 + to All and adds a list of the warnings that need to be turned off. This is + semi-documentary; the intent is to tell libpng users which warnings have + been examined and judged non-fixable at present. The warning about + structure padding is fixable, but it would be a signficant change (moving + structure members around). + +Version 1.6.24beta03 [July 4, 2016] + Optimized absolute value calculation in filter selection, similar to + code in the PAETH decoder in pngrutil.c. Build with PNG_USE_ABS to + use this. + Added pngcp to the build together with a pngcp.dfa configuration test. + Added high resolution timing to pngcp. + Added "Common linking failures" section to INSTALL. + Relocated misplaced #endif in png.c sRGB profile checking. + Fixed two Coverity issues in pngcp.c. + +Version 1.6.24beta04 [July 8, 2016] + Avoid filter-selection heuristic sum calculations in cases where only one + filter is a candidate for selection. This trades off code size (added + private png_setup_*_row_only() functions) for speed. + +Version 1.6.24beta05 [July 13, 2016] + Fixed some indentation to comply with our coding style. + Added contrib/tools/reindent. + +Version 1.6.24beta06 [July 18, 2016] + Fixed more indentation to comply with our coding style. + Eliminated unnecessary tests of boolean png_isaligned() vs 0. + +Version 1.6.24rc01 [July 25, 2016] + No changes. + +Version 1.6.24rc02 [August 1, 2016] + Conditionally compile SSE2 headers in contrib/intel/intel_sse.patch + Conditionally compile png_decompress_chunk(). + +Version 1.6.24rc03 [August 2, 2016] + Conditionally compile ARM_NEON headers in pngpriv.h + Updated contrib/intel/intel_sse.patch + +Version 1.6.24[August 4, 2016] + No changes. + +Version 1.6.25beta01 [August 12, 2016] + Reject oversized iCCP profile immediately. + Cleaned up PNG_DEBUG compile of pngtest.c. + Conditionally compile png_inflate(). + +Version 1.6.25beta02 [August 18, 2016] + Don't install pngcp; it conflicts with pngcp in the pngtools package. + Minor editing of INSTALL, (whitespace, added copyright line) + +Version 1.6.25rc01 [August 24, 2016] + No changes. + +Version 1.6.25rc02 [August 29, 2016] + Added MIPS support (Mandar Sahastrabuddhe <Mandar.Sahastrabuddhe@imgtec.com>). + Only the UP filter is currently implemented. + +Version 1.6.25rc03 [August 29, 2016] + Rebased contrib/intel/intel_sse.patch after the MIPS implementation. + +Version 1.6.25rc04 [August 30, 2016] + Added MIPS support for SUB, AVG, and PAETH filters (Mandar Sahastrabuddhe). + +Version 1.6.25rc05 [August 30, 2016] + Rebased contrib/intel/intel_sse.patch after the MIPS implementation update.. + +Version 1.6.25 [September 1, 2016] + No changes. + +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 1.6.26beta06 [October 7, 2016] + Use zlib-1.2.8.1 inflateValidate() instead of inflateReset2() to + optionally avoid ADLER32 evaluation. + +Version 1.6.26rc01 [October 12, 2016] + No changes. + +Version 1.6.26 [October 20, 2016] + Cosmetic change, "ptr != 0" to "ptr != NULL" in png.c and pngrutil.c + Despammed email addresses (replaced "@" with " at "). + +Version 1.6.27beta01 [November 2, 2016] + Restrict the new ADLER32-skipping to IDAT chunks.
