Re: [Quantlib-users] Deprecated functions in Quantlib

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

Hello,
    deprecated functions stay in the library for four or five more releases
and then they are removed.  The FDAmericanEngine class was deprecated in
version 1.17 and finally removed in version 1.22, so yes, if you upgrade
you'll need to use FdBlackScholesVanillaEngine instead.
