 SimGrid (3.19) NOT RELEASED YET (target: March 20 2018, 16:15:27 UTC)
 
+ MSG
+ - Fix MSG_task_get_remaining_work_ratio() to return 1.0 for tasks that have
+   not started.
+
  S4U
  - Execution->setHost() can be called after start() to migrate it.
+ - Comm::test_any() is now implemented.
+ - s4u::Actor now has an onCreation() signal.
+
+ XBT
+ - Remove XBT_LOG_CONNECT, it should be useless nowadays.
+
+ SMPI
+ - Removed index notion from SMPI -- no more "getPid() - 1"! 
+   This also means that the trace files
+   now contain actors called rank-<PROCESS-ID>. These are NOT the real
+   ranks, because tracing several communicators right now is not supported.
+ - Because of this, smpi_process_index() has now been deprecated and will
+   be removed in 3.21

    Thanks Michael Mercier.
