 SimGrid (3.3.2-svn) unstable; urgency=low
 
+ The "Simplicity does not preceed complexity, but follows it" release.
+
+ The main contributors of this release were (lexical order):
+   Silas De Munck, Stéphane Genaud, Martin Quinson, Cristian Rosa.
+
  SMPI:
   * Implement some more MPI primitives: 
-    MPI_Waitany, MPI_Waitall, MPI_Reduce, MPI_Allreduce
+    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
 
+ 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.
+       
  SURF: 
   * Extract the routing logic into its own object.

     - Use dynar to represent routes (instead of void** + int*)
     - kill link_set (use surf_network_model->resource_set instead)
     - Add a command-line option to choose the routing schema to use
+    - Add three new models: 
+      * Floyd (shortest path computed at initialization)
+      * Dijikstra (shortest path recomputed all the time)
+      * Cached Dijikstra (shortest path computed on need)
+      All these models where contributed by Silas De Munck, and are
+      described in his ICCS09 paper.
 
   * Simplify model declaration
     (less redirections, less function to write when defining a model)
