docs: update family addition discussion
@@ -75,38 +75,31 @@ latest toolchains available in a given release branch. However, if upgrading a
previously installed system, administrators can {\em opt-in} to enable new
variants as they become available. To illustrate this point, consider the
previous \OHPC{}
-1.3.1 release as an example which introduced a new {``gnu7''} compiler variant
-providing GCC 7.x along with runtimes and libraries compiled
-with the newer toolchain. Note that prior to the 1.3.1 release, the {``gnu''} variant was
-available which provided GCC 5.x versions.
-%Component additions are also fair game for \OHPC{} micro releases, and the 1.3.1

+1.3.2 release as an example which contained an {``openmpi''} mpi variant
+providing OpenMPI 1.10.x along with runtimes and libraries compiled
+with this toolchain. That release also contained the {``llvm4''} compiler family
+which has been updated to {``llvm5''} in \OHPC{} 1.3.3.
+In the case where an admin would like to enable the newer {``openmpi3''} toolchain,
installation of these additions is simplified
with the use of \OHPC{}'s meta-packages (see Table~\ref{table:groups} in Appendix
\ref{appendix:manifest}).

+The following example illustrates adding the complete ``openmpi3'' toolchain.
+We leverage the convenience meta-packages containg MPI-dependent buils, and also we
