+ - 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
+
+ Fixed bugs:
+ - #245: migrating an actor does not migrate its execution
+
+SimGrid (3.18) Released December 24 2017
+
+ The "Ho Ho Ho! SimGrid 4 beta is coming to town" release.
+
+ MSG IS NOW DEPRECATED. Please use S4U for new projects.
+ - Support for MSG should not be removed from SimGrid before 2020,
+ but future evolutions will be limited to the integration of
+ user-provided patches.
+
+ S4U New features
+ - s4u::onDeadlock() signal, run before stopping the simulation.
+ - s4u::Exec: asynchronous executions (abstraction of background
+ threads)
+ - s4u::Host->getLoad() returns the achieved speed in flops/s
+
+ S4U API changes
