grass 4.1 (beta? or final?)

[Jim Ludwig]

Hi.  We are still using grass 4.0, and we have a copy of a pamphlet
called "GRASS 4.1 Beta."  After reading it, we think 4.1 could provide
some nice extra features.  We need to know, however, if 4.1 is still
in the beta stage.  Has the final 4.1 version been released?  If not,
when will it be?  What obvious (to you folk) reasons are there for
getting 4.1 (over keeping 4.0)?

Thanks in advance,
  jim
