@@ -5,6 +5,8 @@
 - Implement commodore fujinet-lib functions
 - Add fuji_open_directory2 prototype for applications to send path and
   filter separately rather than in fixed 256 byte buffer with \0 delimiter. Used by CBM.
+- Rework Hash API, provide simpler interface
+- Fill in some COCO parameters in FUJI calls
