                        GINA 2.2 RELEASE NOTES
                        ======================

GINA 2.2 is the next publicly available GINA version after GINA 2.1 
of January 1992.


Overview of Changes since GINA 2.1:
===================================

o  The documentation remains unchanged.

o  CLM now works with CMU CL (16e and up) and Ibuki Lisp.

o  GINA now works with CMU CL, although background processes are not available.

o  Tetris now has the usual pieces, not simply rectangles.

o  New demo application: diagram-editor.

o  The inspector was replaced with a new one. There is only one window with
   a list of objects to select from.

o  The browser includes a new facility to generate code for subclassing and 
   overriding methods of GINA.

o  The menu entry "Reply History" is now available as the "Play" button in
   the history scroller.

o  The CLX functions copy-plane and copy-area are now available as GINA
   functions to support future hooks.

Minor incompatible changes:
---------------------------

- Method (submit cmd) will not be called when (executable cmd) fails but
  instead method not-submitted will be called.
  (In Gina 2.1 submit was called but did nothing. Method not-submitted 
  is of class drag-command and mouse-down-command.)

- Some others (which we unfortunately do not remember exactly :-)

Experimental Extensions:
------------------------

There are some experimental extensions in GINA that are probably not stable
enough to be used generally (so there is no documentation for them yet). These
features include:

o  A first version of the TAP mechanism (see paper available by FTP).

o  Postscript printing (optional "postscript.lisp").

o  The GINA interaction recorder (see paper available by FTP).
   Optional "interaction-rec.lisp".
