Libpng 1.6.13 - August 21, 2014 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-1.6.13.tar.xz (LZMA-compressed, recommended) libpng-1.6.13.tar.gz Source files with CRLF line endings (for Windows), without the "configure" script lpng1613.7z (LZMA-compressed, recommended) lpng1613.zip Other information: libpng-1.6.13-README.txt libpng-1.6.13-LICENSE.txt libpng-1.6.13-*.asc (armored detached GPG signatures) Changes since the last public release (1.6.12): Quieted -Wsign-compare and -Wclobber compiler warnings in contrib/pngminus/*.c Added "(void) png_ptr;" where needed in contrib/gregbook to quiet compiler complaints about unused pointers. Split a long output string in contrib/gregbook/rpng2-x.c. Added "PNG_SET_OPTION" requirement for sRGB chunk support to pnglibconf.dfa, Needed for write-only support (John Bowler). Changed "if defined(__ARM_NEON__)" to "if (defined(__ARM_NEON__) || defined(__ARM_NEON))" (James Wu). Fixed clang no-warning builds: png_digit was defined but never used. Fixed an incorrect separator ("/" should be "\") in scripts/makefile.vcwin32 (bug report from Wolfgang S. Kechel). Bug was introduced in libpng-1.6.11. Also fixed makefile.bc32, makefile.bor, makefile.msc, makefile.intel, and makefile.tc3 similarly. Removed scripts/makefile.elf. It has not worked since libpng-1.5.0beta14 due to elimination of the PNG_FUNCTION_EXPORT and PNG_DATA_EXPORT definitions from pngconf.h. Ensure that CMakeLists.txt makes the target "lib" directory before making symbolic link into it (SourceForge bug report #226 by Rolf Timmermans). Added opinion that the ECCN (Export Control Classification Number) for libpng is EAR99 to the README file. Eliminated use of "$<" in makefile explicit rules, when copying $PNGLIBCONF_H_PREBUILT. This does not work on some versions of make; bug introduced in libpng version 1.6.11. Made "ccopts" agree with "CFLAGS" in scripts/makefile.hp* and makefile.*sunu Send comments/corrections/commendations to png-mng-implement at lists.sf.net (subscription required; visit https://lists.sourceforge.net/lists/listinfo/png-mng-implement to subscribe) or to glennrp at users.sourceforge.net Glenn R-P
