-Changes since the last public release (1.6.29):
-
- Added missing "$(CPPFLAGS)" to the compile line for c.pic.o in
- makefile.linux and makefile.solaris-x86 (Cosmin).
- Revised documentation of png_get_error_ptr() in the libpng manual.
- Silence clang -Wcomma and const drop warnings (Viktor Szakats).
- Update Sourceforge URLs in documentation (https instead of http).
- Document need to check for integer overflow when allocating a pixel
- buffer for multiple rows in contrib/gregbook, contrib/pngminus,
- example.c, and in the manual (suggested by Jaeseung Choi). This
- is similar to the bug reported against pngquant in CVE-2016-5735.
- Removed reference to the obsolete PNG_SAFE_LIMITS macro in the documentation.
- Check for integer overflow in contrib/visupng and contrib/tools/genpng.
- Do not double evaluate CMAKE_SYSTEM_PROCESSOR in CMakeLists.txt.
- Test CMAKE_HOST_WIN32 instead of WIN32 in CMakeLists.txt.
- Fix some URL in documentation.
- Avoid writing an empty IDAT when the last IDAT exactly fills the
- compression buffer (bug report by Brian Baird). This bug was
- introduced in libpng-1.6.0.
- Update copyright year in pnglibconf.h, make ltmain.sh executable.
- Add a reference to the libpng.download site in README.

+ libpng-1.6.31-*.asc (armored detached GPG signatures)
+
+Changes since the last public release (1.6.30):
+
+ Guard the definition of _POSIX_SOURCE in pngpriv.h (AIX already defines it;
+ bug report by Michael Felt).
+ Revised pngpriv.h to work around failure to compile arm/filter_neon.S
+ ("typedef" directive is unrecognized by the assembler). The problem
+ was introduced in libpng-1.6.30beta01.
+ Added "Requires: zlib" to libpng.pc.in (Pieter Neerincx).
+ Added special case for FreeBSD in arm/filter_neon.S (Maya Rashish).
+ Added instructions for disabling hardware optimizations in INSTALL.
+ Added "--enable-hardware-optimizations" configuration flag to enable
+ or disable all hardware optimizations with one flag.
+ Updated CMakeLists.txt to add INTEL_SSE and MIPS_MSA platforms.
+ Changed "int" to "png_size_t" in intel/filter_sse2.c to prevent
+ possible integer overflow (Bug report by John Bowler).
+ Quieted "declaration after statement" warnings in intel/filter_sse2.c.
+ Added scripts/makefile-linux-opt, which has hardware optimizations enabled.
+ Removed one of the GCC-7.1.0 'strict-overflow' warnings that result when
+ integers appear on both sides of a compare. Worked around the others by
+ forcing the strict-overflow setting in the relevant functions to a level
+ where they are not reported (John Bowler).
+ Changed "FALL THROUGH" comments to "FALLTHROUGH" because GCC doesn't like
+ the space.
+ Worked around some C-style casts from (void*) because g++ 5.4.0 objects
+ to them.
+ Increased the buffer size for 'sprint' to pass the gcc 7.1.0 'sprint
+ overflow' check that is on by default with -Wall -Wextra.
+ Added eXIf chunk support.
+ Added a minimal eXIf chunk (with Orientation and FocalLengthIn35mmFilm
+ tags) to pngtest.png.
