+\subsection{Boot files containing compiled library code fail to load}
+
+Compiled library code may now appear within fasl objects loaded during
+the boot process, provided that they are appended to the end of the base boot
+file or appear within a later boot file.

 \subsection{Misleading cyclic dependency error (9.5)}
