FreeBSD ports

[Pete]

I am about to go live with my first FreeBSD machine, I used the devel
branch of the mailscanner port.

When the beta/devel branch turns into a final/release product - does
that mean the last of the betas is now one release behind? So to have
the latest version, would have to switch from mailscanner-devel to
mailscanner ?

If the above is true, then would it be possible to release a new beta
relase, maybe for the next 'series'/release number so both versions are
current ?

Thanks
Pete
