  cMSG:
  * Interface improvement:
    - Rename MSG_host_is_avail(h) to MSG_host_is_on(h)
+   - Sanitize the interface in MSG_task_ module:
+     - Merge two functions that were close enough but misleading:
+       set_compute_duration(t)      -> set_flops_amount(t)
+       get_remaining_computation(t) -> set_flops_amount(t)
+     - set_data_size(t) -> set_bytes_amount(t)
+       get_data_size(t) -> get_bytes_amount(t)
    - Massive cleanups in the functions related to the energy
+     - MSG_host_get_pstate_number() -> MSG_host_get_nb_pstates()
+   - New: MSG_host_get_pstate()
+ * New example:
+   - msg/energy/onoff: switching hosts on and off
  jMSG:
  * Interface improvement:
    - Rename Host.isAvail() to Host.isOn()
+   - Rename Process.currentProcess() to Process.getCurrentProcess()
+   - Rename Task.setDataSize() to Task.setBytesAmount()
+   - Merge Task.getRemainingDuration() and Task.getComputeDuration() into Task.getFlopsAmount()

    - popping: the strange dance that converts a user request into a kernel handling
    - smx_context_*: the virtualization mechanisms that embeed the user code
    - smx_*: the handling of each simcalls
+ * Interface cleanup:
+   - simcall_host_set_power_peak_at -> simcall_host_set_pstate
  * Rename smx_action_t into smx_synchro_t, making explicit that these
    things are used to synchronize processes with their environment.    
    For example, a communication is a sort of synchronization involving
    the communicating processes (that may block until the exchange) and
    the platform. The same can be said from computations, etc.

    - Replay can be used with SMP-aware algorithms
    - Memory occupation of replay should now be contained (temporary buffers allocated in collective algorithms should be shared between processes)
    - Replay can now replay several traces at the same time (check examples/smpi/replay_multiple example), to simulate interactions between several applications on a given platform. User can specify the start time of each instance. This should also allow replay + actual applications to run.

   * Improvement of the Energy plugin.
     - Always update the consumption before returning that value
     - New property: watt_off to denote the disipation when the host is off
+    - New functions getWattMinAt and getWattMaxAt to retrieve the
+      dissipation of pstates that we are not currently at.
+  * Massive rename s/workstation/host/
+    - That's intrusive, but that's good for the project consistency. Sorry. 
+    - Change config option "workstation/model" into "host/model"
  XBT
   * New functions
    - Add a xbt_heap_update function, to avoid costly xbt_heap_remove+xbt_heap_insert use 
    - Add a xbt wrapper for simcall_mutex_trylock (asked in [#17878])
    - Add two new log appenders : rollfile and splitfile. Patch by Fabien Chaix.

+ Build System
+  * Require g++ v4.7 at least to not speak prehistorical C++.
+  * Tracing is now always enabled (no way to turn it out)
+  * Move headers around to sort them out on installed systems:
+    - instr/instr.h  -> simgrid/instr.h
+    - instr/jedule/* -> simgrid/jedule
+    - simdag/datatypes.h was removed
+    - simdag/simdag.h -> simgrid/simdag.h
+    - msg/datatypes.h was removed
+    - msg/msg.h -> simgrid/msg.h
+
+ MC
+  * The model checker now runs as a separate process.
+  * The model checker runs must now be launched with the new simgrid-mc program.
+  * Record/Replay: the MC can display a textual representation of a path in the
+    execution graph. It can then be replayed outside of the model checker.
