     + Something added
     * Something changed / fixed

V0.4-pre5:
 * Fixed bug which could take server down with a dead client
 * Fixed small scroller bug
 + Added "frame" widgets..  use "-in <frame_name>" after widget_add
   to put something in a frame.
 + The disk screen is back!
 - Frame rendering isn't finished..  the renderer probably needs a
   complete rewrite.  Any volunteers?  :)

V0.4-pre4:
 + Server menus (fairly small so far)
 + Ability to shut down, reboot, change some options, etc (menu only)
 * Driver arguments no longer required
 * Curses driver doesn't start server in background any more...
 * Argument handling fixed...

 * Proper errno messages...
 * "make install" should work now
 * Joystick driver allows key remapping
 + Screen "durations" are actually *used* now.  (oops)

 + Drivers support parameters now (MtxOrb, joy, at least)


V0.4-pre2:
 * Memory leaks fixed
 + Memory "top" screen (S)
 + Titles now autoscroll
 * Fixed small screen-visibility bug  (clients weren't always
   notified of screen cycles)
 + Heartbeat modes implemented.  Clients can remove it with
	     widget_del my_screen heartbeat
   or turn it back on with
	     widget_add my_screen heartbeat " "
   Note that the client only has control over this when the heartbeat
   is in "open" mode.  (currently, it always is)
