Changes since the last public release (1.4.7):

version 1.4.8beta01 [June 4, 2011]
  Undef "_ALL_SOURCE" for AIX, to prevent "jmpbuf" from being redefined.
  Copied png_debug macros from pngpriv.h into pngtest.c and removed
    "#include pngpriv.h" from pngtest.c, to avoid setting a bad example.
  Pass "" instead of '\0' to png_default_error() in png_err().  This mistake
    was introduced in libpng-1.2.20beta01.
  Check for up->location !PNG_AFTER_IDAT when writing unknown chunks
    before IDAT.
  Ported bugfix in pngrtran.c from 1.5.3: when expanding a paletted image,
    always expand to RGBA if transparency is present.

version 1.4.8beta02 [June 5, 2011]
  Ported bugfix in pngrtran.c from 1.5.3: Ensure coefficients are OK for
    png_rgb_to_gray_fixed().

version 1.4.8beta03 [June 6, 2011]
  Check for integer overflow in png_set_rgb_to_gray().
