Okay, but hardly anyone reads that, and I can't blame them. :)

For example, if I use something like Lua, I won't read a release announcement
from 2012.

As Jurjen said, the presence of the FFT (actually fast number theoretic
transform here) in Decimal is something completely unexpected, so if there's
a place for a line or two in the docs that makes some users happy I'd be
in favor of it.
