+ SMPI:
+  * This is the first release of SimGrid where SMPI is not considered
+    beta anymore (even if some corners should still be improved)
+  * Port over the new SIMIX_network submodule (internal refactoring)
+  * Basic support to log events as with SMPE (use --cfg=SMPE:1)
+  * Implement more missing elements of the standard:
+    - MPI_COMM_SELF 
+    - MPI_MAXLOC MPI_MINLOC + all associated datatype MPI_DOUBLE_INT,
+      MPI_FLOAT_INT, etc.
+    - MPI_Address() MPI_Get_count() MPI_Type_free() MPI_Type_extent()
+      MPI_Scan() MPI_Get_processor_name()
+    - Added implementation of missing case for Alltoall (warning: it's
+      *not* the bruck variant from OpenMPI; based on Alltoallv instead)
+    - SMPI_MPI_Gather() SMPI_MPI_Gatherv() SMPI_MPI_Scatterv()
+      SMPI_MPI_Reduce_scatter() SMPI_MPI_Allgather()
+      SMPI_MPI_Allgatherv() 
+  * Bug fixes include:
+    - MPI_Waitsome() was broken
+    - Allow relative includes in smpicc
+    - Command line cfg argument 'reference_speed' was ignored...
+    - Some functions did not properly lead to auto-benching of user code
+    - smpicc passes -O2 by default (just like openmpi one)
