+The variable BAUD is no longer set automatically by the shell.
+In previous versions it was set to the baud rate reported by
+the terminal driver in order to initialise the line editor's
+compensation mechanism for slow baud rates.  However, the baud
+rate so reported is very rarely related to the limiting speed of

 The variable HOME is no longer set by the shell if zsh is emulating any
 other shell at startup; it must be present in the environment or set
 subsequently by the user.  It is valid for the variable to be unset.
