26:  What is different about GNU Emacs 19?                                   !
  
  From the January 1992 GNU's Bulletin:                                      !
                                                                             !
    Version 19 will enter beta test late this year.  Among its new features  !
    are: before and after change hooks, source-level debugging of Emacs Lisp
    programs, X selection processing (including clipboard selections),
    scrollbars, support for European character sets, floating point numbers,
    per-buffer mouse commands, X resource manager interfacing,
    mouse-tracking, Lisp-level binding of function keys, multiple X windows
    (`screens' to Emacs), a new input system, and buffer allocation, which
    uses a new mechanism capable of returning storage to the system when a
    buffer is killed.
  
    The input stream is now a sequence of Lisp objects, instead of a         !
    sequence of characters.  This allows a reasonable representation for     !
    mouse clicks, function keys, menu selections, etc.                       !
  
    Thanks go to Alan Carroll and the people who worked on Epoch for
    generating initial feedback to a multi-windowed Emacs, and to Eric       !
    Raymond for help in polishing the Emacs 19 Lisp libraries.               !
                                                                             !
  The June 1991 GNU's bulletin had this to say about future plans for Emacs: !
  
    Features being considered for later releases of Emacs include:
    associating property lists with regions of text in a buffer; multiple
    fonts, color, and pixmaps defined by those properties; different
    visibility conditions for the regions, and for various windows showing
    one buffer; hooks to be run if point or mouse moves outside a certain
    range; incrementally saving undo history in a file; static menu bars;
    and better pop-up menus.
  
  Mention of this feature disappeared in the January 1992 GNU's bulletin:    !
  
    Emacs 19 supports two styles of multiple windows, one with a separate
    screen for the minibuffer, and another with a minibuffer attached to
    each screen.
  
  Mention of these two proposed features disappeared in the January 1991     !
  GNU's bulletin:
  
  * Incremental syntax analysis for various programming languages (Leif).
  * A more sophisticated emacsclient/server model, which would provide
    network transparent Emacs widget functionality.
