+ - Global signals are now part of the Engine:
+ - on_platform_creation: after config settings, before the XML parsing
+ - on_platform_created: right after the XML parsing
+ - on_time_advance: each time the clock advances
+ - on_simulation_end: after simulation, before cleanups
+ - on_deadlock: as the name implies.
+ - C bindings:
+ - sg_{actor,host,link}_{data,data_set}() now all exist.
+ Use them to attach user data to the object and retrieve it.
+
+Models:
+ - Introduce an experimental Wifi model. It sounds reasonable
+ according to the state of the art, but it still has to be properly
+ validated, at least against ns-3 if not against reality.
+ - Improved the usability of ns-3. Several bugs were ironed out.
+ - host_energy: Wattage was expressed as 'idle:oneCore:allCores'.
+ It is now expressed as 'idle:epsilon:allCores' to properly model the
+ consumption of non-whole tasks on mono-core hosts. More info in the doc.
