No.
To get access to the latest releases you also need the latest software version.
Whenever we release a new Materia Medica, Repertory, function etc, it is locked with the version of RadarOpus available at that time.
E.G. we release Rep 1 in RadarOpus version 3.3, this means that you cannot get Rep 1 if you have RadarOpus version 3.2 or 3.1 and below.
