Any special reason for what?  That I never found a reason to go any further
than v2.5e?  Well, the one I use plays whatever which is what I want.  It
doesn't have a "library" feature which I don't want because there are other
far better MP3 database managers.
Basically, any improvements to later 2.x versions were ones that I didn't
want.  Additionally, many of those "improvements" fixed bugs introduced
after the one I use.
Salient points of all Winamp 2.x versions...
