As far as I can see, it is.

That is one of the major changes between 1.36 and 1.38 versions.

Change that using the scheme you found in the current manual - 
autochanger resource plus device setup. You already have all the 
information you need in the configuration, you've only got to move parts 
around.

By the way - this has not happened to make life harder for the users, 
but to support autochangers with more than one tape drive.
