libpng-1.6.31beta04-*.asc (armored detached GPG signatures)
-Changes since the last public release (1.6.29):
-
-Version 1.6.30beta01 [April 1, 2017]
- Added missing "$(CPPFLAGS)" to the compile line for c.pic.o in
- makefile.linux and makefile.solaris-x86 (Cosmin).
- 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.

Quieted "declaration after statement" warnings in intel/filter_sse2.c.

-Version 1.6.31beta04 [July 9, 2017]
+Version 1.6.31beta04 [July 11, 2017]
+ Removed one of the GCC-7.1.0 'strict-overflow' warnings that result when
+ integers appear on both sides of a compare. Worked around the others by
+ forcing the strict-overflow setting in the relevant functions to a level
+ where they are not reported (John Bowler).
+ Changed "FALL THROUGH" comments to "FALLTHROUGH" because GCC doesn't like
+ the space.
+ Worked around some C-style casts from (void*) because g++ 5.4.0 objects
+ to them.
+ Increased the buffer size for 'sprint' to pass the gcc 7.1.0 'sprint
+ overflow' check that is on by default with -Wall -Wextra.
