 within a few weeks by a public version or by another test version.

   Avoid some tests in filter selection in pngwutil.c
 
-version 1.4.0beta69 [July 20, 2009]
+version 1.4.0beta69 [July 23, 2009]
   Simplified the new filter-selection test.  This runs faster in the
     common "PNG_ALL_FILTERS" and PNG_FILTER_NONE cases.
   Removed extraneous declaration from the new call to png_read_gray_to_rgb()
     (bug introduced in libpng-1.4.0beta67).
   Fixed up xcode project (Alam Arias)
+  Declared internal png_64bit_product() static.
 
 version 1.4.0betaN [future]
   Build shared libraries with -lz and sometimes -lm.
