Next Lispworks release?

I am using cormanlisp until now, but now I am interested in lispworks,
because I need a integrated GUI.
When I watch the release history on xanalys I see the following:

4.2     on  19.12.2001
4.2.6  on  15.5.2002
4.2.7  on  2.10.2002

What are the plans for the near future?

A minor, free release 4.2.X or a 4.3 or a 5.0?

Any info about that to make the right decision?
