        should consider redoing your old experiments with this model.
      Sorry for the inconvenience.
 
+ MSG:
+ * Port of MSG's mailbox on top of SIMIX network
+   The put/get mechanism was greatly simplified thanks to the new SIMIX module.
+
+ SIMIX:
+ * New SIMIX network module
+   It provides a rendez-vous point (aka mailbox) based send/recv API to perform
+   synchronous communication. 
+   
+ SimDag:
+ * new function SD_daxload(char*) to load a DAX file 
+   (see http://vtcpc.isi.edu/pegasus/index.php/WorkflowGenerator)
+ * Introduce typed tasks. Specify its kind and cost at creation. 
+   At scheduling, just give where it should be placed, and the cost
+   for each involved resource is automatically computed.
+   Existing constructors so far (more to come of course):
+    - SD_task_create_comm_e2e() for end-to-end communication
+    - SD_task_create_comp_seq() for sequential computation
+   Use SD_task_schedulev() / SD_task_schedulel() to schedule them.
+ * new function SD_task_dump() for debuging display
+ * new function SD_task_dotty(task,FILE*) writing to file the info
+   about the task in dotty format
+ * SD_task_dependency_exists() can now cope with having one of its
+   arguments NULL. If so, it tests whether the other argument has any 
+   dependency.
+ * Add getters on list of preceding/following tasks:
+    SD_task_get_parents(task) and SD_task_get_children(task)
+ * Add getters on amount of workstations and list:
+    SD_task_get_workstation_count(t) and SD_task_get_workstation_list(t)
+ * Add getter on task kind: SD_task_get_kind(task)
+ * Update the start_time and finish_time of tasks on completion/failure
+ * Bugfix: Remove task from state swags when destroyed
+ 
+ GRAS:
+ * New function: void gras_cpu_burn(double flops) -- a simple CPU burner
+
+ XBT:
+ * New function: xbt_dynar_dopar(dynar,fun) to map a function over the
+   dynar with one separate thread per value of the dynar.
+ * Change the prototype of xbt_thread_create(), sorry. 
+   Added a boolean parameter indicating whether we want to join this
+   thread (used in SG only for now)
+ * Implement xbt_thread_join and xbt_thread_yield in SG also.
+   
  Bug fixes:
+ * GTNetS wrappers should now be usable again (and betterly tested too)
  * Fix a major regression from 3.2 where the timeout provided to
    MSG_task_put_with_timeout() was used as absolute time before which
    the comm should be done.
+ * Start to fix the <cluster> tag. 
+   - Internal links should be good now (beside of the loopback, which
+     use the private link instead)
+   - paths to the external world is still rather broken
+   - the <route:multi> tag is just broken. Actually that's brain-dead.
+     We need sth like <route:multi src="myCluster" dst="$*-${myCluster}">
+     to make it less stupid
+   ** Check your platform with teshsuite/simdag/platforms/flatifier **
  * Fix a source-level compatibility glitch from 3.2: after defining
    MSG_USE_DEPRECATED, you can use the old name
    MSG_task_put_with_time_out() for MSG_task_put_with_timeout()
  * Allow to compile from the SVN with automake 1.11
  * Fix some problems when using the "start_time" tag in deployment XMLs.
+ * Fix #8569: XBT/synchro.h has redundant declarations
+ * Fix #8563: MSG return values and exceptions
+   Introduce a MSG_TIMEOUT_FAILURE return code and use it consistently.
+ * Integrate patch #8636: Obey DESTDIR when installing documentation.
+   Thanks to Robson Peixoto.
+ * Fix a vicious bug in dictionaries inducing that some elements were
+   not freed on xbt_dict_free()
