+	also safe for initial file name for invalid UTF-8 and non-UTF-8 filesystems.

+
+	* ltclass.dtx:
+	    Update to suspicious rollback code for issue #43
+            Make the suspicious rollback message a warning not error.
+            Make the current and latest options to latexrelease set the
+            default rollback request to 0 so package rollback is disabled.

 No changes to the format, but \texttt{docstrip} adjusted so that non-ASCII
