+ * Improve the action object model
+ - implement a constructor avoiding dupplicated code about field
+ initialization in generic_action part.
+
+ * Kill the SDP model: it has an external dependency, is deprecated
+ in flavor of modern lmm models, and didn't compile since a while
+
+ SIMIX:
+ * Relocation of the context module from XBT to SIMIX.
+ (the context were decoupled from the simix processes, duplicating a lot of code)
+ => a lot of code was factorized
+ - less overhead is introduced during scheduling
+ - simpler API for the context factory
+ - the logic for process creation,destruction and manipulation was simplified
+ * Simplification of the s_smx_process_t data structure.
+ => accesing the simix level data associated to a process is faster now,
+ and the code is a lot more readable.
+
+ SMPI:
+ * Implement some more MPI primitives:
+ MPI_Bcast, MPI_Waitany, MPI_Waitall, MPI_Reduce, MPI_Allreduce, MPI_Scatter, MPI_Sendrecv, MPI_Alltoall
+ -implementation: Bcast: flat or 2-ary tree (default),
+ Barrier: 4-ary tree,
+ Reduce: flat tree
+ Allreduce: Reduce then Bcast
+ Alltoall: "basic_linear" if data per proc < 3Kb, "otherwise pairwise".
+ Not yet implemented: "Bruck" for data per proc < 200b and comm size > 12
+ Alltoallv: flat tree, like ompi
+ Scatter: flat tree
+ * Add support for optimized collectives (Bcast is now binomial by default)
+ * Port smpirun and smpicc to OS X
+
+ SimDag:
+ * Kill SD_link_get_properties: hard to maintain and makes very little sense
+ Shout out if you used it.
+
+ GRAS:
+ * Display the list of still queued messages in SG mode when existing
+ the process.
