+\section{General rollback concept for packages and classes}
+
+  In 2015 a rollback concept for the \LaTeX{} kernel was introduced.
+  Providing this feature allowed us to make corrections to the
+  software (which more or less didn't happen for nearly two decades)
+  while continuing to maintain backward compatibility to the highest
+  degree.
+  
+  In this release we have now extended this concept to
+  the world of packages and classes which was not covered
+  initially. As the classes and the extension packages have different
+  requirements compared to the kernel, the approach is different (and
+  simplified). This should make it easy for package developers to
+  apply it to their packages and authors to use when necessary.
+
+  The documentation of this new feature is given in an article
+  submitted to TUGboat and also available from our
+  website~\cite{Mittelbach:TB39-2}.
