initial-major-mode, which normally is lisp-interaction-mode,
instead of using default-major-mode.
+** The new option `Info-scroll-prefer-subnodes' causes Info to behave
+like the stand-alone Info reader (from the GNU Texinfo package) as far
+as motion between nodes and their subnodes is concerned. If it is t
+(the default), Emacs behaves as before when you type SPC in a menu: it
+visits the subnode pointed to by the first menu entry. If this option
+is nil, SPC scrolls to the end of the current node, and only then goes
+to the first menu item, like the stand-alone reader does.
+
+This change was already in Emacs 21.1, but wasn't advertised in the
+NEWS.
