Re: [Quantlib-users] Release candidate for QuantLib 1.44

[Luigi B. <lui...@gm...>]

Hi Dirk, I suspect it's because 26.04 still carries swig 4.4.0.  We're
currently using the latest, 4.5.1.  I'm not sure how to solve the problem
of versions lagging behind, other than relying on our tarballs (that
already contain the generated wrapper, but that I haven't provided for the
pre-release; I might do that next time though).
