+Version 1.5.23beta02 [June 2, 2015]
   Removed WRITE_WEIGHTED_FILTERED code, to save a few kbytes of the
     compiled library size. It never worked properly and as far as we can
     tell, no one uses it. The png_set_filter_heuristics() and
     png_set_filter_heuristics_fixed() APIs are retained but deprecated
     and do nothing.
+  Quieted Coverity issues in pngvalid.c.
