 	- Compile
 * Added support for Finder Icons File ($CA or "ICN").
 * Added CP/M disk image support.
+* Restructured how AppleCommander manages disk ordering.  This simplifies the
+  manner in which various disk ordering schemes are implemented, and makes it
+  possible to translate between ordering schemes.
+* Support for nibble images (*.NIB) added.  Can read and write to the images
+  as long as that format supports writing.
+* To support nibble images, changed the structure surrounding the disk image
+  for a Disk.  There now is an ImageOrder which manages the ordering of data on
+  the image and supplies low-level read and write routines (track/sector and 
+  block).  An ImageOrder holds data in an image layout - this allows the generic
+  byte array and 2IMG layouts to be abstracted away from an images order.  This
+  does add interaction complexity but actually simplified the Disk class.
+!!!! ROB:
+o Add the ability to change physical order too.
+o Viewing or double-clicking on a directory crashes AppleCommander.
+o Add a View As menu pick and drop-down on toolbar.  (ie, view as Text or binary)
+o Viewing a deleted file can (always?) crash AppleCommander.
+o Need to update Export Graphics wizard as well as export right-click options.
+o Fix UniDOS and OzDOS formats.
