Changes since the last public release (1.6.23):
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

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 "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
