+\section{Version 1.6}
+
+The following list describes the specific changes in \openshmem[1.6]:
+\begin{itemize}
+
+\item Added \FUNC{shmem\_initialized} and \FUNC{shmem\_finalized} to
+  provide a query mechanism for the state of the \openshmem library.
+
+\end{itemize}
+
 \section{Version 1.5}
 Major changes in \openshmem[1.5] include the addition of new team-based
 collective functions, \OPR{put-with-signal} functions, nonblocking \ac{AMO}

+  \FUNC{shmem\_initialized} may return \CONST{0} to one thread while
