Should I use version 2.0.* or 2.1.*

[Colin Hogben]

Hi,
I am trying to use tramp-mode to access some GNU/Linux boxen from 
emacs-22.2.1 on a WindowsXP machine.  Before I try to resolve my 
specific problem, I want to make sure I am running the right version of 
tramp, and I'm a little confused:

- The documentation at http://www.gnu.org/software/tramp/ is for 2.1.13 
and does not mention the 2.0.* versions.

- The latest emacs (22.2.1) includes tramp, but version 2.0.57

- from the dates of (and in) the tarfiles, it seems that the 2.1 
development branch was forked over four years ago, and that both 
branches have been updated several times since.

So which version is preferred?  If 2.1.*, why does a recent emacs not 
use it?  If 2.0.*, should not the tramp web site mention it?

Hope someone can clarify.

Thanks,
