Revised documentation of png_get_error_ptr() in the libpng manual. Silence clang -Wcomma and const drop warnings (Viktor Szakats). Update Sourceforge URLs in documentation (https instead of http). Version 1.6.30beta02 [April 22, 2017] Document need to check for integer overflow when allocating a pixel buffer for multiple rows in contrib/gregbook, contrib/pngminus, example.c, and in the manual (suggested by Jaeseung Choi). This is similar to the bug reported against pngquant in CVE-2016-5735. Removed reference to the obsolete PNG_SAFE_LIMITS macro in the documentation. Version 1.6.30beta03 [May 22, 2017] Check for integer overflow in contrib/visupng and contrib/tools/genpng. Do not double evaluate CMAKE_SYSTEM_PROCESSOR in CMakeLists.txt. Test CMAKE_HOST_WIN32 instead of WIN32 in CMakeLists.txt. Fix some URL in documentation. Version 1.6.30beta04 [June 7, 2017] Avoid writing an empty IDAT when the last IDAT exactly fills the compression buffer (bug report by Brian Baird). This bug was introduced in libpng-1.6.0. Version 1.6.30rc01 [June 14, 2017] No changes. Version 1.6.30rc02 [June 25, 2017] Update copyright year in pnglibconf.h, make ltmain.sh executable. Add a reference to the libpng.download site in README. Version 1.6.30 [June 28, 2017] No changes. Version 1.6.31beta01 [July 5, 2017] Guard the definition of _POSIX_SOURCE in pngpriv.h (AIX already defines it; bug report by Michael Felt). Revised pngpriv.h to work around failure to compile arm/filter_neon.S ("typedef" directive is unrecognized by the assembler). The problem was introduced in libpng-1.6.30beta01. Added "Requires: zlib" to libpng.pc.in (Pieter Neerincx). Added special case for FreeBSD in arm/filter_neon.S (Maya Rashish).
