+ - 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
