 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_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
 
  SURF: 
   * Extract the routing logic into its own object.

     => kill now useless network_card concept
     - 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)

   * Implement a generic resource; use it as ancestor to specific ones
     (allows to kill duplicated code in models)
-    TODO: integrate the properties into that ancestor
+    Drawback: timer command don't need no name nor properties;
+              workstation_CLM03 don't need no properties
+    (but I guess we can live with those few bytes wasted)
+    
+  * 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
+ 
+ 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.
+
  XBT:
   * Add xbt_set_get_by_name_or_null() [Silas De Munck]
   * Add xbt_graph_node_get_outedges() [Silas De Munck]
+  * Add xbt_str_from_file(FILE*)
+  * Add xbt_dict_get_key achieving a linear reverse search
