\subsection{Fix wrong file type in a rollback warning}

When \LaTeX{} is rolled back to date \meta{date1} and a class or
package with minimum date requirement \meta{date2} is to be loaded, a
rollback warning is raised if \meta{date2} is later than \meta{date1}:
\begin{verbatim}
LaTeX Warning: Suspicious rollback/min-date date given
               A minimal date of YYYY-MM-DD has been specified for package
               '<pkgname>'.
               But this is in conflict with a rollback request to YYYY-MM-DD.
\end{verbatim}

In some cases this message showed a wrong file type, i.e.,
\verb|document class '<pkgname>'| or \verb|package '<clsname>'|.
This has now been corrected.

\subsection{\pkg{doc}:\ \cs{PrintDescribeMacro} in preamble}

In \pkg{doc} version 2 it was possible alter the definition of
\cs{PrintDescribeMacro} and similar commands in preamble. In version 3
this stopped working because they go reset at the end of the
preamble. This has now been implemented differently and changes in the
preamble are possible again.
