@ -3919,6 +3919,76 @@ Version 1.5.13rc01 [September 17, 2012]
Version 1.5.13 [September 27, 2012]
No changes.
Version 1.5.14beta01 [October 24, 2012]
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).
Version 1.5.14beta02 [omitted]
Version 1.5.14beta03 [December 15, 2012]
Added missing "-" in front of DNO_GZIP in contrib/pngminim/*/makefile.
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.
Version 1.5.14beta04 [December 19, 2012]
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).
Version 1.5.14beta05 [December 23, 2012]
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.
Version 1.5.14beta06 [January 1, 2013]
Discontinued distributing libpng-1.5.14-1.5.13-diff.txt and similar.
Fixed 'make distcheck' on SUN OS - libpng.so was not being removed
Version 1.5.14beta07 [January 6, 2012]
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.
Version 1.5.14beta08 [January 10, 2013]
Check validity of "num_unknowns" parameter of png_set_unknown_chunks()
(Bug report from yuris).
Version 1.5.14rc01 [January 17, 2013]
No changes.
Version 1.5.14rc02 [January 17, 2013]
Revised test for validity of "num_unknowns" to eliminate compiler warnings.
Version 1.5.14rc03 [January 18, 2013]
Check the validity of the "nentries" parameter of png_set_sPLT() and the
"num_text" parameter of png_set_text_2().
Version 1.5.14 [January 24, 2013]
Removed an obsolete line from the manual.

XIV. Y2K Compliance in libpng
September 27, 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 1.5.13 are Y2K compliant. It is my belief that earlier
upward through 1.5.14 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.
