Libpng 1.6.15 - November 20, 2014
Libpng 1.6.16beta01 - November 21, 2014
This is a public release of libpng, intended for use in production codes.
This is not intended to be a public release. It will be replaced
within a few weeks by a public version or by another test version.
Files available for download:
Source files with LF line endings (for Unix/Linux) and with a
"configure" script
libpng-1.6.15.tar.xz (LZMA-compressed, recommended)
libpng-1.6.15.tar.gz
1.6.16beta01.tar.xz (LZMA-compressed, recommended)
1.6.16beta01.tar.gz
Source files with CRLF line endings (for Windows), without the
"configure" script
lpng1615.7z (LZMA-compressed, recommended)
lpng1615.zip
lp1616b01.7z (LZMA-compressed, recommended)

Changes since the last public release (1.6.14):
Changed "if (!x)" to "if (x == 0)" and "if (x)" to "if (x != 0)"
Simplified png_free_data().
Added missing "ptr = NULL" after some instances of png_free().
Made a one-line revision to configure.ac to support ARM on aarch64
(bug report by Marcin Juszkiewicz, fix by John Bowler).
Avoid out-of-bounds memory access in png_user_version_check().
Simplified and future-proofed png_user_version_check().
Fixed GCC unsigned int->float warnings. Various versions of GCC
seem to generate warnings when an unsigned value is implicitly
converted to double. This is probably a GCC bug but this change
avoids the issue by explicitly converting to (int) where safe.
Free all allocated memory in pngimage. The file buffer cache was left
allocated at the end of the program, harmless but it causes memory
leak reports from clang.
Fixed array size calculations to avoid warnings. At various points
in the code the number of elements in an array is calculated using
sizeof. This generates a compile time constant of type (size_t) which
is then typically assigned to an (unsigned int) or (int). Some versions
of GCC on 64-bit systems warn about the apparent narrowing, even though
the same compiler does apparently generate the correct, in-range,
numeric constant. This adds appropriate, safe, casts to make the
warnings go away.
Removed #ifdef PNG_16BIT_SUPPORTED/#endif around png_product2(); it is
needed by png_reciprocal2().
Added #ifdef PNG_16BIT_SUPPORTED/#endif around png_log16bit() and
png_do_swap().
Changed all "#endif /* PNG_FEATURE_SUPPORTED */" to "#endif /* FEATURE */"
The macros passed in the command line to Borland make were ignored if
similarly-named macros were already defined in makefiles. This behavior
is different from POSIX make and other make programs. Surround the
macro definitions with ifndef guards (Cosmin).
Added "-D_CRT_SECURE_NO_WARNINGS" to CFLAGS in scripts/makefile.vcwin32.
Removed the obsolete $ARCH variable from scripts/makefile.darwin.
Changes since the last public release (1.6.15):
Version 1.6.16beta01 [November 21, 2014]
