** Changes related to multiple-terminal (multi-tty) support
----
*** $TERM is now set to `dumb' for subprocesses. If you want to know the
$TERM inherited by Emacs you will have to look inside initial-environment.
----
*** $DISPLAY is now dynamically inherited from the frame's `display'.

*** The `window-system' variable is now frame-local. The new
`initial-window-system' variable contains the `window-system' value
for the first frame. `window-system' is also now a function that
takes a frame argument.
