\chapter{Major changes in TeXmacs}

Below, we list the major changes which have occurred in TeXmacs
since version 0.3.3.15. In general, when upgrading to a new version,
we recommend you to make backups of your old TeXmacs files before
opening them with the newer version of TeXmacs. In the unlikely case when
your old file does not open in the correct way, please send a bug report to
\begin{verbatim}
    bugs@texmacs.org
\end{verbatim}
and send your old document as an attached file.
Do not forget to mention your version of
TeXmacs and the system you are using.
