In May 2004, feature freeze for Emacs 22 was announced. In order to
not disturb (and delay) Emacs 22, we have created Tramp 2.1, where all
new features went to.

Unfortunately, it took still 3 years, until Emacs 22 was
released. Some months before that release we have been asked, whether
we could upgrade to Tramp 2.1 in Emacs 22. We've denied this due to
stability concerns.

Last year's summer, after the release of Emacs 22, we have declared
Tramp 2.1 to be the upstream version. Tramp 2.0 will experience
updates only in case of serious problems. Tramp 2.0.57 is just the
release tag for what have been delivered with Emacs 22.2; it was never
announced officially.

So the answer is short: if you don't have problems with Emacs 22 and
Tramp 2.0, keep it as it is. If there are problems, we will try to
support your Tramp 2.0 version.

However, better support will be available for Tramp 2.1. And there are
other advantages as well; Tramp 2.1 has a better performance compared
to Tramp 2.0.

Emacs 23, which is said to have feature freeze this summer, will carry
Tramp 2.1. I hope it doesn't take another 3 years until release.
