Libpng 1.5.20 - November 20, 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-1.5.20.tar.xz (LZMA-compressed, recommended) libpng-1.5.20.tar.gz libpng-1.5.20.tar.bz2 Source files with CRLF line endings (for Windows), without the "configure" script lpng1520.7z (LZMA-compressed, recommended) lpng1520.zip Other information: libpng-1.5.20-README.txt libpng-1.5.20-LICENSE.txt libpng-1.5.20-*.asc (armored detached GPG signatures) Changes since the last public release (1.5.19): Removed "option WRITE_COMPRESSED_TEXT enables WRITE_TEXT" from pnglibconf.dfa Only mark text chunks as written after successfully writing them. Avoid out-of-bounds memory access in png_user_version_check(). Simplified and future-proofed png_user_version_check(). Quieted three "comparison is always false due to limited range" compiler warnings in pngset.c The macros passed in the command line to Borland make were ignored if similarly-named macros were already defined in makefiles. This behavior is different from POSIX make and other make programs. Surround the macro definitions with ifndef guards (Cosmin). Use memcpy instead of CopyMemory in the definition of png_memcpy. The Borland C++ build breaks otherwise (Cosmin). Added "-D_CRT_SECURE_NO_WARNINGS" to CFLAGS in scripts/makefile.vcwin32 Removed the obsolete $ARCH variable from scripts/makefile.darwin.
