Re: Add M-x occur to the menu-bar

      * Installation Changes in Emacs 21.4

    + ** next-error and previous-error were moved from compile.el to
    +    simple.el, and are always loaded.  Also, the way that next-error
    +    finds the buffer in which to advance has changed; occur-mode uses
    +    the new interface.

That is internal, not worth mentioning in NEWS.

    + 
    + ** occur-mode can advance to the next/previous error with next-error
    +    and previous-error
    + 

That is the feature worth mentioning.  It should be in the following
section, "Changes in Emacs 21.4", not in the Installation Changes
section.
