The boyz at YaBB released a new version of their forum script: v2.5 .. which celebrates their 10-year anniversary. Radified has been using YaBB since June, 2001 (v1.0-Gold).

I installed a copy of the new version here:

.. but need to wait until they update a few mods I use, so they work with the new version.

Looks like a lot of stuff.

YaBB is written in Perl.

They've been working on a complete rewrite called YaBB v3.0 for a long time. Maybe 18 months or even 2 years:

Interesting how YaBB is a Perl script, but their info site is PHP.

FAIK Y3 is still pre-alpha.
