Changes since the last public release (1.6.2):

Version 1.6.3beta01 [April 25, 2013]
  Revised stack marking in arm/filter_neon.S and configure.ac.
  Ensure that NEON filter stuff is completely disabled when switched 'off'.
    Previously the ARM NEON specific files were still built if the option
    was switched 'off' as opposed to being explicitly disabled.

Version 1.6.3beta02 [April 26, 2013]
  Test for 'arm*' not just 'arm' in the host_cpu configure variable.
  Rebuilt the configure scripts.

Version 1.6.3beta03 [April 30, 2013]
  Expanded manual paragraph about writing private chunks, particularly
    the need to call png_set_keep_unknown_chunks() when writing them.
  Avoid dereferencing NULL pointer possibly returned from
     png_create_write_struct() (Andrew Church).

Version 1.6.3beta04 [May 6, 2013]
  Calculate our own zlib windowBits when decoding rather than trusting the
    CMF bytes in the PNG datastream.

Version 1.6.3beta05 [May 8, 2013]
  Choose to use windowBits==15 or the zlib header setting via the
    benign-errors setting.  If benign errors are allowed, then ignore
    the windowBits setting in the zlib header.
  Zlib-1.2.8 and earlier don't allow us to decrease the windowBits, so
    undid the improvement in beta04.
  Check for EOF in contrib/pngminus/pnm2png.c (Paul Stewart).
  Ignore "#" delimited comments in input file to pnm2png.c.
  Added an option to force maximum window size for inflating. For inflate,
    reverted previous fixes.
  Added fixitxt and pngdeflate to the built programs and removed warnings
    from the source code and timepng that are revealed as a result.  Fixed
    fixitxt when the chunk length is more than 65535 (untested, no test case).
