+ * New data container: setset (set of sets of elements)
+ * New module: mmalloc (mapped malloc)
+ * New function: xbt_dict_cursor_set_data()
+ * New function: xbt_fifo_get_last_item()
+ * Bug fix in xbt_dynar_shrink(): use the right element size
+ * Use library init/fini functions for our initialization.
+   - you can use logs and other feature as soon as you want in your
+     code (even before the xbt_init / MSG_init)
+   - xbt_exit is now a no-op and produce a warning when used.
+
+ Build chain: bug fixes and further polishing
+ * Fix the 'make install' target. 
+   No need to use 'make install-simgrid' anymore
+ * Introduce a 'make dist' target compiling a *source* archive
+   'make package' compiles a binary archive (not well tested)
+ * Compile java files only on need

+ * Fix a bug occuring when a host involved in a communication fails.
+   This was not detected properly by the other peer involved in the

+ * Warn the user about loop dependencies in data flow of DAX files
+ * Obey the control-flow dependencies of DAX files
+
+ Cmake
+ * Add option "enable_smpi" allowing to not compile SMPI.

+ * Improve the detection of lua5.1 and ruby1.8

+  * the "se habla Java, Ruby 話せます, fala-se Lua (and deaf-friendly)"
+    ~> bindings were greatly improved
+    ~> new tracing infrastructure for better visualization introduced

+  * Allow task_execute() on 0-sized tasks (closes #10063)
+ 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)

-  * Bugfix: Handle correctly the resume/suspend of processes when they
-      are blocked on semaphores.
+  * Bug fixes about timeouts during communications
+  * add SIMIX_message_sizes_output() as a pimple to write to file the
+    amount of messages per size. Use gnuplot to get histogram. 
+    Pimple because that's the only user-visible function of simix,
+     defined directly in xbt.h (irk, sorry)
+  * About semaphores:
+     - Add a SIMIX_sem_get_capacity() function
+     - Fix interactions with processe resume/suspende
+     - release_forever() was stupidly broken
+     - Fix SIMIX_display_process_status() for processes in a semaphore
+     - Make SIMIX_sem_block_onto() user-visible
+  * Refactoring context stuff:
+    - Use pseudo-OOP for better modularity
+    - reimplement SIMIX_process_kill() without process_schedule() so
+      that the latter can take as invariant that it is called from
+      maestro.
+    - Merge context_start into context_new for sake of simplicity
