   * Make JniException a runtime exception, so that there is no need to
     declare the fact that you may encounter such a beast. I guess that
     nobody will ever want to survive such error.
- Ruby Bindings: create it
-  * That's new and great, you should try it out. 
-    Kinda the same functionalities than Java bindings
+  * Create specific errors for each MSG case of failure:
+    host failure, transfer failure, timeout, task cancelled
+ Ruby and Lua Bindings: create them
+  * That's new and great, you should try them out. 
+    Same functionalities than Java bindings, only even less polished
  SimDag:
   * Kill the useless "rate" argument of SD_task_get_execution_time()

       and call MSG_action_trace_run(NULL)
     You can still have one merged file for each processes.
   * Kill the MSG_paje_output() function. It's a noop since 2 years.
+  * Kill MSG_WARNING and MSG_FATAL return codes: they were not used
+    anywere in source.
+  * Add a MSG_task_set_data() function
  SIMIX:
   * add a SIMIX_sem_get_capacity() function
-      
+  * add SIMIX_action_suspend() and SIMIX_action_resume() functions
+  * Bugfix: Handle correctly the resume/suspend of processes when they
+      are blocked on semaphores.
+ SURF:
+  * Rename configuration variables to start a hierarchy:
+    o cpu_model -> cpu/model
+    o network_model -> network/model
+    o workstation_model -> workstation/model
+  * New configuration variables:
+    o network/bandwidth_factor: correction to bandwith
+    o network/latency_factor: correction to latency
+    o netwotk/weight_S: correction to the weight of competing streams
+  * Add a long description to the models, that users can see with such
+    argument on the command line: --cfg=cpu/model:help
+  * --help-models display the long description of all known models
+ SMPI:
+  * Implement MPI_Get_count, MPI_MAXLOC, MPI_MINLOC
+ XBT:
+  * config: add the ability to set a default value after registration
+    Does not override any previously set value (e.g. from cmd line)
+  * dict: allow to have integer key and data.
+    When so, you need to use the following functions
+     void xbt_dicti_set(xbt_dict_t dict, uintptr_t key, uintptr_t data);
+     uintptr_t xbt_dicti_get(xbt_dict_t dict, uintptr_t key);
+     void xbt_dicti_remove(xbt_dict_t dict, uintptr_t key);
+    In contrary to regular dicts, the key is not malloced before copy.
+    Mixing scalar and regular elements in the same dict is not tested 
+      (but may work).
+ Tracing for Visualization:
+  * SimGrid is now instrumented in order to generate a trace file for
+    visualization analysis: to use it, need to compile SimGrid with the
+    "tracing" option enabled, and instrument the program using SimGrid with
+    TRACE_start, TRACE_category, TRACE_msg_set_task_category and TRACE_end
+    (among other functions).
+  * The instrumentation only traces the platform utilization for now
+  * Documentation to use the tracing functions and how to analyze the
+    traces with the Triva tool is written.
+  * More information about: SimGrid FAQ (in the section Tracing Simulations
+    for Visualization)
