Version 2.0.6.

Version 2.0.6.
(tramp-default-method): Change to "ssh" from "sm".
(tramp-wrong-passwd-regexp): Restructure.  Add additional
alternative.
(tramp-su-program): New internal variable for method parameter.
(tramp-perl-encode-with-module, tramp-perl-decode-with-module):
New variables.  Very short Perl one-liner, but requires Perl
module MIME::Base64 to be installed on the remote site.
(tramp-perl-encode, tramp-perl-decode): New base64
encoder/decoder.  From Juanma Barranquero <lektu@terra.es>.
(tramp-handle-file-truename): Invoke Ange-FTP properly (even
though Ange-FTP doesn't do anything for this operation).
(tramp-handle-set-visited-file-modtime): Comment change.
(tramp-handle-make-directory): Save-excursion.
(tramp-handle-expand-many-files): Don't try to invoke Ange-FTP
twice, once is enough.
(tramp-action-permission-denied): Show *tramp/foo* buffer so the
user knows what's wrong.
(tramp-post-connection): Support the two Perl encoders and
decoders.
(tramp-coding-commands): Ditto.  Add some todo items.
