-  Zero out all arrays of pointers after png_malloc(). (Tavis Ormandy)
-  Use png_memset() instead of a loop to intialize pointers.  We realize
-    this will not work on platforms where the NULL pointer is not all zeroes.
+  Removed an extra png_debug() recently added to png_write_find_filter().
+  Fixed incorrect #ifdef in pngset.c regarding unknown chunk support.
+  Various bugfixes and improvements to CMakeLists.txt (Philip Lowman)
