Changes since the last public release (1.2.36):

version 1.2.37 [June 2, 2009]

  Fixed inconsistency in pngrutil.c, introduced in libpng-1.2.36.  The
    memset() was using "png_ptr->rowbytes" instead of "row_bytes", which
    the corresponding png_malloc() uses (Joe Drew).
  Clarified usage of sig_bit versus sig_bit_p in example.c (Vincent Torri)
  Updated some of the makefiles in the scripts directory.
  Fixed typo in libpng documentation (FILTER_AVE should be FILTER_AVG)
  Relocated misplaced #endif in pngwrite.c, sCAL chunk handler.
  Conditionally compile png_read_finish_row() which is not used by
    progressive readers.
  Added contrib/pngminim/preader to demonstrate building minimal progressive
    decoder, based on contrib/gregbook with embedded libpng and zlib.
  In contrib/pngminim/*, renamed "makefile.std" to "makefile", since there
    is only one makefile in those directories, and revised the README files
    accordingly.
  Reformated sources in libpng style (3-space indentation, comment format)
  Added sections about the git repository and our coding style to the
    documentation (merged from libpng-1.4.0beta62)
  Added a section about using png_get_io_ptr() in configure scripts to detect
    the presence of libpng.
