   Update to 1.6.8:

   Version 1.6.8beta01 [November 24, 2013]
     Moved prototype for png_handle_unknown() in pngpriv.h outside of
       the #ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED/#endif block.
     Added "-Wall" to CFLAGS in contrib/pngminim/*/makefile
     Conditionally compile some unused functions reported by -Wall in
       pngminim.
     Fixed 'minimal' builds. Various obviously useful minimal configurations
       don't build because of missing contrib/libtests test programs and
       overly complex dependencies in scripts/pnglibconf.dfa. This change
       adds contrib/conftest/*.dfa files that can be used in automatic build
       scripts to ensure that these configurations continue to build.
     Enabled WRITE_INVERT and WRITE_PACK in contrib/pngminim/encoder.
     Fixed pngvalid 'fail' function declaration on the Intel C Compiler.
       This reverts to the previous 'static' implementation and works round
       the 'unused static function' warning by using PNG_UNUSED().

   Version 1.6.8beta02 [November 30, 2013]
     Removed or marked PNG_UNUSED some harmless "dead assignments" reported
       by clang scan-build.
     Changed tabs to 3 spaces in png_debug macros and changed '"%s"m'
       to '"%s" m' to improve portability among compilers.
     Changed png_free_default() to free() in pngtest.c

   Version 1.6.8rc01 [December 12, 2013]
     Tidied up pngfix inits and fixed pngtest no-write builds.

   Version 1.6.8rc02 [December 14, 2013]
     Handle zero-length PLTE chunk or NULL palette with png_error()
       instead of png_chunk_report(), which by default issues a warning
       rather than an error, leading to later reading from a NULL pointer
       (png_ptr->palette) in png_do_expand_palette(). This is CVE-2013-6954
       and VU#650142.

   Version 1.6.8 [December 19, 2013]

   Log Message:
   Update to 1.6.9, getting rid of the final two patches after discussion
   with very helpful upstream.

   Changes:

   Version 1.6.9beta01 [December 26, 2013]
     Bookkeeping: Moved functions around (no changes). Moved transform
       function definitions before the place where they are called so that
       they can be masde static. Move the intrapixel functions and the
       grayscale palette builder out of the png?tran.c files. The latter
       isn't a transform function and is no longer used internally, and the
       former MNG specific functions are better placed in pngread/pngwrite.c
     Made transform implementation functions static. This makes the internal
       functions called by png_do_{read|write}_transformations static. On an
       x86-64 DLL build (Gentoo Linux) this reduces the size of the text
       segment of the DLL by 1208 bytes, about 0.6%. It also simplifies
       maintenance by removing the declarations from pngpriv.h and allowing
       easier changes to the internal interfaces.
     Rebuilt configure scripts with automake-1.14.1 and autoconf-2.69
       in the tar distributions.

   Version 1.6.9beta02 [January 1, 2014]
     Added checks for libpng 1.5 to pngvalid.c.  This supports the use of
       this version of pngvalid in libpng 1.5
     Merged with pngvalid.c from libpng-1.7 changes to create a single
       pngvalid.c
     Removed #error macro from contrib/tools/pngfix.c (Thomas Klausner).
     Merged pngrio.c, pngtrans.c, pngwio.c, and pngerror.c with libpng-1.7.0
     Merged libpng-1.7.0 changes to make no-interlace configurations work
       with test programs.
     Revised pngvalid.c to support libpng 1.5, which does not support the
       PNG_MAXIMUM_INFLATE_WINDOW option, so #define it out when appropriate in
       pngvalid.c
     Allow unversioned links created on install to be disabled in configure.
       In configure builds 'make install' changes/adds links like png.h
       and libpng.a to point to the newly installed, versioned, files (e.g.
       libpng17/png.h and libpng17.a). Three new configure options and some
       rearrangement of Makefile.am allow creation of these links to be 
disabled.

   Version 1.6.9beta03 [January 10, 2014]
     Removed potentially misleading warning from png_check_IHDR().

   Version 1.6.9beta04 [January 20, 2014]
     Updated scripts/makefile.* to use CPPFLAGS (Cosmin).
     Added clang attribute support (Cosmin).

   Version 1.6.9rc01 [January 28, 2014]
     No changes.

   Version 1.6.9rc02 [January 30, 2014]
     Quiet an uninitialized memory warning from VC2013 in png_get_png().

   Version 1.6.9 [February 6, 2014]

   Log Message:
   Update to 1.6.10rc01:
   This fixes CERT VU#684412 and CVE-2014-0333.

   Version 1.6.10beta01 [February 9, 2014]
     Backported changes from libpng-1.7.0beta30 and beta31:
     Fixed a large number of instances where PNGCBAPI was omitted from
       function definitions.
     Added pngimage test program for png_read_png() and png_write_png()
       with two new test scripts.
     Removed dependence on !PNG_READ_EXPAND_SUPPORTED for calling
       png_set_packing() in png_read_png().
     Fixed combination of ~alpha with shift. On read invert alpha, processing
       occurred after shift processing, which causes the final values to be
       outside the range that should be produced by the shift. Reversing the
       order on read makes the two transforms work together correctly and 
mirrors
       the order used on write.
     Do not read invalid sBIT chunks. Previously libpng only checked sBIT
       values on write, so a malicious PNG writer could therefore cause
       the read code to return an invalid sBIT chunk, which might lead to
       application errors or crashes.  Such chunks are now skipped (with
       chunk_benign_error).
     Make png_read_png() and png_write_png() prototypes in png.h depend
       upon PNG_READ_SUPPORTED and PNG_WRITE_SUPPORTED.
     Support builds with unsupported PNG_TRANSFORM_* values.  All of the
       PNG_TRANSFORM_* values are always defined in png.h and, because they
       are used for both read and write in some cases, it is not reliable
       to #if out ones that are totally unsupported. This change adds error
       detection in png_read_image() and png_write_image() to do a
       png_app_error() if the app requests something that cannot be done
       and it adds corresponding code to pngimage.c to handle such options
       by not attempting to test them.

   Version 1.6.10beta02 [February 23, 2014]
     Moved redefines of png_error(), png_warning(), png_chunk_error(),
       and png_chunk_warning() from pngpriv.h to png.h to make them visible
       to libpng-calling applications.
     Moved OS dependent code from arm/arm_init.c, to allow the included
       implementation of the ARM NEON discovery function to be set at
       build-time and provide sample implementations from the current code in 
the
       contrib/arm-neon subdirectory. The __linux__ code has also been changed 
to
       compile and link on Android by using /proc/cpuinfo, and the old linux 
code
       is in contrib/arm-neon/linux-auxv.c.  The new code avoids POSIX and Linux
       dependencies apart from opening /proc/cpuinfo and is C90 compliant.
     Check for info_ptr == NULL early in png_read_end() so we don't need to
       run all the png_handle_*() and depend on them to return if info_ptr == 
NULL.
       This improves the performance of png_read_end(png_ptr, NULL) and makes
       it more robust against future programming errors.
     Check for __has_extension before using it in pngconf.h, to
       support older Clang versions (Jeremy Sequoia).
     Treat CRC error handling with png_set_crc_action(), instead of with
       png_set_benign_errors(), which has been the case since 
libpng-1.6.0beta18.
     Use a user warning handler in contrib/gregbook/readpng2.c instead of 
default,
       so warnings will be put on stderr even if libpng has CONSOLE_IO disabled.
     Added png_ptr->process_mode = PNG_READ_IDAT_MODE in png_push_read_chunk
       after recognizing the IDAT chunk, which avoids an infinite loop while
       reading a datastream whose first IDAT chunk is of zero-length.
       This fixes CERT VU#684412 and CVE-2014-0333.
     Don't recognize known sRGB profiles as sRGB if they have been hacked,
       but don't reject them and don't issue a copyright violation warning.

   Version 1.6.10beta03 [February 25, 2014]
     Moved some documentation from png.h to libpng.3 and libpng-manual.txt
     Minor editing of contrib/arm-neon/README and contrib/examples/*.c

   Version 1.6.10rc01 [February 27, 2014]
     Fixed typos in the manual and in scripts/pnglibconf.dfa (CFLAGS -> CPPFLAGS
       and PNG_USR_CONFIG -> PNG_USER_CONFIG).
