When you open a document, TeXmacs looks at the
version number, and translates the old format
accordingly to update it to the current version.

Thus in case of problems, updating this import
code of TeXmacs is the solution.


A more complete answer to your question is:

1. In case import doesn't work well, updating
  the import code would solve the problem. Thus
  it is only a matter of looking at the features
  in the old versions and then submitting a patch
  for translating the old features ;

2. In any case, TeXmacs files are markup stored in
  pure text files, and this markup is usually highly
  readeable (this is not at all the case in markup
  formats like, e.g. ooxml). Thus in the future,
  it will always remain possible to open a TeXmacs
  document in emacs and to hack out the offending
  part of the markup (of course this approach is
  not perfect, but at least, it shows that in this
  respect, users are in control) ;
