Changes since the last public release (1.6.28):
Changes since the last public release (1.6.29):
Readded "include(GNUInstallDirs)" to CMakeLists.txt (Gianfranco Costamagna).
Moved SSE2 optimization code into the main libpng source directory.
Configure libpng with "configure --enable-intel-sse" or compile
libpng with "-DPNG_INTEL_SSE" in CPPFLAGS to enable it.
Simplified conditional compilation in pngvalid.c, for AIX (Michael Felt).
Avoid conditional directives that break statements in pngrutil.c (Romero
Malaquias)
The contrib/examples/pngtopng.c recovery code was in the wrong "if"
branches; the comments were correct.
Added code for PowerPC VSX optimisation (Vadim Barkov).
Avoid potential overflow of shift operations in png_do_expand() (Aaron Boxer).
Change test ZLIB_VERNUM >= 0x1281 to ZLIB_VERNUM >= 0x1290 in pngrutil.c
because Solaris 11 distributes zlib-1.2.8.f that is older than 1.2.8.1.
Suppress clang warnings about implicit sign changes in png.c
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.
