# 1.4.0
##############################

------
Added the ability to specify voltage gain (gv=) or power gain (gp=) as
well as input/output resistances (rin=, rout=).  At this time, the
calculations still assume matched conditions between each stage (ie,
loading is not accounted for).  This lets you specify a transformer
as:

   transformer rin=50 rout=200 gp=0

------
Added a new 'defaults' keyword.  This lets you specify the default
input resistance (rin=), default output resistance (rout=), and
default 3rd order intermodulation distortion correlation coefficient
(rho=).  The 'defaults' keyword can be used anywhere in the cascade
which is useful for changing defaults part way through the system.
For example, a CATV receiver might start with 75 ohms:

   defaults rin=75 rout=75

and part way through the chain switch to 50 ohms:

   defaults rin=50 rout=50

------
Open circuit and matched impedance voltage levels are now reported.

------
Added a new comment line start '@'.  When a line like
@ a verbose comment
is found in the input file, it is echo'ed to the output.  This lets
you add annotations to the output.

------
The emacs mode for cascade is now semi-functional (font-lock works, 
but running cascade from within emacs isn't finished) and is installed.

------
cascade is now released under a BSD license which is much less restrictive
than the previous license
