-Version 1.6.26beta01 [September 3, 2016]
+Version 1.6.26beta01 [September 12, 2016]
   Fixed handling zero length IDAT in pngfix (bug report by Agostino Sarubbo,
     bugfix by John Bowler).
   Do not issue a png_error() on read in png_set_pCAL() because png_handle_pCAL
     has allocated memory that libpng needs to free.
+  Conditionally compile png_set_benign_errors() in pngread.c
