Dear users (or future users) of the SVAR addon,

I guess we forgot to mention the updates to versions 1.51 and 1.52 in
recent months. You should be able to get those from the Help menu under
"Look for addons" (or similar wording in English, sorry I usually run
gretl in the German translation). For new gretl installations these are
automatically included.

The brand new v1.52 is not a big update and essentially includes some
fixes for SVECs (cointegrated SVARs), especially when there are weakly
exogenous variables present. (When the loadings matrix alpha is fixed
and includes some rows with only zeros. - And BTW, "fixes" does not mean
that previous results were wrong, only that something wasn't working
before.)

The previous updates v1.5 and  v1.51 released back in September are
perhaps of more general interest; the central new feature is to deal
with heteroscedastic residuals through various new bootstrap variants to
get more reliable confidence bands for the impulse responses in those
cases.

These and other changes are documented inside the PDF help document of
the SVAR addon.

Needless to say, if you find any bugs or anything that isn't working, it
would be helpful to provide feedback, preferably (but not necessarily)
here on this list.

Thanks

sven
