Interestingly, #FreeBSD comes with #nvi2 in base, while #OpenBSD and #NetBSD seem to be running #nvi 1:
FreeBSD 14.3-RELEASE-p12

Version 2.2.2 (2025-10-08) The CSRG, University of California, Berkeley.
OpenBSD 7.3
(7.9 is still running the same version)

Version 1.79 (10/23/96) The CSRG, University of California, Berkeley.
NetBSD 10.1
~
~
~
Version (1.81.6-2013-11-20nb4) The CSRG, University of California, Berkeley.
They all seem to have nvi2 available as packages, though, which #Debian, oddly, does not.
