IMHO, having a separate SCIHOME directory for each scilab version is fine.
This does not necessarily demand to initialize SCIHOME configuration 
files with "factory files" shipped with the release, at the first run, 
as it is currently done.

This initialization could be done with configuration files of a previous 
most recent Scilab release, provided that configuration files are tagged 
with the scilab version that generated (or upgraded) them as proposed by 
Stephane.
This would improve the continuity of usage.
However, detecting a previous version on the same computer is not so 
obvious.

Currently, scilab user preferences are not extremely numerous, and as 
long as scilab releases won't be more frequent, resetting preferences by 
hand for each release is feasable and not blocking.
But for softwares and freewares that propose frequent upgrades, handling 
the copy or upgrade of configuration files in an automatic way is just 
mandatory.

PS: by the way, i thing that, as a general rule, tagging a generated 
file with the (name and) version of the software that generated it is 
wise and dramatically improves files backward compatibility. This could 
be done as well for .scg files (i don't thing they are tagged), .zcos 
files (may be they already are), . dat ones (from save()), etc.
