This release has changes to the "elaboration" phase of simulation.
There are three differences you will see ..

1. (Important!)
It fixes a bug that sometimes caused incorrect parameter values
in some cases.  The bug would manifest with a certain combination
of subcircuits, models, and parameters.

In particular, something like this would give bad results:

.subckt foo (a k)
.model dio d (is={isat})
dfoo (a k) dio
.ends

...
x1 (1 2) foo isat=1u
x2 (2 3) foo isat=2u
...

......  would have the wrong value of isat.

Circuits that did not have this combination of models, subckt, and params
did not have this problem.


2. (cosmetic)
Taming of redundant warnings that would be printed in the
elaboration phase.  Also, bad parameter warnings from 
spice models using plugins are now printed, only once,
on readin, instead of multiple times on elaboration.

3. (new models)
The tarball "models-bsim" includes new models, including
the new BSIM4SOI, released Sep 22 and the new BSIM465,
release Sep 9.

As usual, to get started you need only the main package
