samba - Nov 1998 - need help with CVS tree updates

Hi, 

Can someone explain how to use CVS to keep in sync with samba updates?  I
tried following the CVS_ACCESS.txt file, but it always seems to be behind
the "current" release of samba.  For example, right now if I do

  cvs -d :pserver:cvs@samba.org:/cvsroot login
  cvs -d :pserver:cvs@samba.org:/cvsroot co samba

I end up with 2.0.0beta1.  But 2.0.0beta2 has already been released.
(I'm looking at the header of the WHATSNEW.txt file to determine version)

  cvs update -d -P in the samba directory doesn't help.

Thanks...
