Most users probably don't need to upgrade.  If you are 
having trouble with an assert failure when using Spice
model plugins, or if you are developing plugins, you 
should upgrade.


This release has one minor bug fix in spice-wrapper.cc,
and some changes to the interface to simulation data.

The bug would cause an assertion failure, with some circuits.
It is minor in the sense that the real code was correct.  It was the
check that was wrong.  You could just remove the line with the failure.
There is a proper fix in this release.


There are changes in organization regarding the "language" plugins, 
changing them to single files which will make them easier to manage
as plugins.  This change is not significant to most users.

There are changes to the access to simulation data.  In particular,
there are new files "sim_data.h" and "sim_data.cc", and static
pointer "_sim" in CKT_BASE.  This is probably not significant to most
users, but if you have any custom plugins, they will need to be changed.

There are two reasons for the change.  The first is to improve
incapsulation, making a cleaner boundary between core
and what could be a plugin.  The second is as a step toward being
able to store multiple simulation runs for postprocessing.


As usual, to get started you need only the main package 
gnucap-2009-xx-xx.tar.gz .  

You need to recompile all of the plugins with the new headers
and wrappers.
