Libpng 1.5.14 - January 24, 2013 This is a public release of libpng, intended for use in production codes. Files available for download: Source files with LF line endings (for Unix/Linux) and with a "configure" script libpng-1.5.14.tar.xz (LZMA-compressed, recommended) libpng-1.5.14.tar.gz libpng-1.5.14.tar.bz2 Source files with CRLF line endings (for Windows), without the "configure" script lpng1514.7z (LZMA-compressed, recommended) lpng1514.zip Other information: libpng-1.5.14-README.txt libpng-1.5.14-LICENSE.txt 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(). =========================================================================== NOTICE November 17, 2012: The location of the git repository at SourceForge has changed.
