Changes since the last public release (1.5.13):
Added -DZ_SOLO to contrib/pngminim/*/makefile to work with zlib-1.2.7
Warn about the incorrect runtime library setting for VS2010 debug DLL builds.
Fixed build when using #define PNG_NO_READ_GAMMA in png_do_compose() in
pngrtran.c (Domani Hannes).
Check for png_ptr==NULL earlier in png_zalloc().
Ignore, with a warning, out-of-range value of num_trans in png_set_tRNS().
Rearranged building of ARM NEON optimizations. The ARM specific code is
split out entirely to the arm subdirectory and changes to configure.ac and
Makefile.am to add new stuff are reduced. Now material code changes,
although for build test purposes, --enable-arm-neon now builds on non-ARM
systems.
Rebuilt Makefile.in, configure, etc., with autoconf-2.69 and automake-1.12.5.
Fixed cases of unquoted DESTDIR in Makefile.am
Fixed a minor bug in types to malloc and major bug in handling compressed
iTXt. Compressed iTXt could not be handled.
Cleaned up whitespace in the synopsis portion of the manpage "libpng.3"
Disassembled the version number in scripts/options.awk (necessary for
building on SunOs).
Fixed Windows build issues, enabled ARM compilation. Various warnings issued
by earlier versions of GCC fixed for Cygwin and Min/GW (which both use old
GCCs.) ARM support is enabled by default in zlib.props (unsupported by
Microsoft) and ARM compilation is made possible by deleting the check for
x86. The test programs cannot be run because they are not signed.
Fixed 'make distcheck' on SUN OS - libpng.so was not being removed
Replaced AM_CONFIG_HEADER(config.h) with AC_CONFIG_HEADERS([config.h])
in configure.ac
De-configured build fixes to make a range of deconfiguration options (such
as switching off read or write support) work in more cases. Also upgraded
pngtest and pngvalid to the libpng 1.6 versions (with some modifications)
which provide more extensive testing. Replaced pngtest.png because pngtest
writes the ancillary chunks in a different order.
Check validity of "num_unknowns" parameter of png_set_unknown_chunks()
(Bug report from yuris).
Revised test for validity of "num_unknowns" to eliminate compiler warnings.
Check the validity of the "nentries" parameter of png_set_sPLT() and the
"num_text" parameter of png_set_text_2().
Removed scripts/makefile.cegcc from the *.zip and *.7z distributions; it
depends on configure, which is not included in those archives.
Changed "a+w" to "u+w" in Makefile.in to fix CVE-2012-3386.

Changed "a+w" to "u+w" in Makefile.in to fix CVE-2012-3386.
Version 1.5.13beta01 [August 8, 2012]
Do not compile PNG_DEPRECATED, PNG_ALLOC and PNG_PRIVATE when __GNUC__ < 3.
Removed references to png_zalloc() and png_zfree() from the manual.
Revised PNG_FP_EXPORT and PNG_FIXED_EXPORT macros to avoid generating
lone semicolons (patch ported from libpng-1.6.0beta11).
Version 1.5.13beta02 [September 10, 2012]
Corrected handling of the image array and the row_pointers array in example.c
When png_set_filler is used to strip a filler channel during write, the
code prior to 1.5 would ignore the case where the output required an
alpha channel or when the output was a palettized PNG. In libpng-1.5 the
ignorance was lost and libpng proceeded to strip the channel resulting
in a bad (potential memory overwrite) failure later. This reverts
the behavior to the pre-1.5 state but issues a warning. libpng-1.6 is
expected to issue an error on the erroneous png_set_filler call.
Use png_memset() consistently (pngmem.c contained some bare "memset" calls).
Version 1.5.13rc01 [September 17, 2012]
No changes.
Version 1.5.13 [September 27, 2012]

pngrtran.c (Domani Hannes).
Version 1.5.14beta02 [omitted]
Version 1.5.14beta03 [December 15, 2012]
Added missing "-" in front of DNO_GZIP in contrib/pngminim/*/makefile.

Using the ./configure script -- 16 December 2002.
=================================================
The ./configure script should work compatibly with what scripts/makefile.*
did, however there are some options you might need to add to configure
explicitly, which previously was done semi-automatically (if you didn't edit
scripts/makefile.* yourself, that is)
CFLAGS="-Wall -O -funroll-loops \
-malign-loops=2 -malign-functions=2" ./configure --prefix=/usr/include \
--with-pkgconfigdir=/usr/lib/pkgconfig --includedir=/usr/include
You can alternatively specify --includedir=/usr/include, /usr/local/include,
/usr/include/libpng%NN%, or whatever.
If you find that the configure script is out-of-date or is not supporting
your platform properly, try running autogen.sh to regenerate "configure",
"Makefile.in", and the other configuration files. Then try configure again.

XIV. Y2K Compliance in libpng
July 11, 2012
January 24, 2013
Since the PNG Development group is an ad-hoc body, we can't make
an official declaration.
This is your unofficial assurance that libpng from version 0.71 and

upward through 1.5.14 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.
Libpng only has two year fields. One is a 2-byte unsigned integer that
