  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
  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()
+ * Bug fixes:
+   - #18874: Actually allows the GC to reclaim tasks
+   
  SIMIX:
  * New functions
    - SIMIX_process_throw: raises an exception in a remote process
+ * Refactoring: Separate submodules
+   - libsmx: the public interface, as libc in a real system
+   - 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
+ * 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.
+ * Bug fixes:
+   - #18888: segfault when a process ends before its kill_time
+   
  SMPI: 
  * New functions
    - Onesided early support for : MPI_Win_(create, free, fence, get_name, set_name, get_group), MPI_Get, MPI_Put, MPI_Accumulate, MPI_Alloc_mem, MPI_Free_mem. 
    - MPI_Keyval*, MPI_Attr* functions, as well as MPI_Comm_attr*, MPI_Type_attr* variants (C only, no Fortran support yet)
    - MPI_Type_set_name, MPI_Type_get_name
    - MPI_*_c2f and MPI_*_f2c functions
+   - MPI_Info_* functions (beware, get_nthkey may not follow the insertion order)
+   - MPI_Pack, MPI_Unpack and MPI_Pack_size functions
    - Activate a lot of new tests from the mpich 3 testsuite
  * Features 
    - Constant times can be injected inside MPI_Wtime and MPI_Test through options smpi/wtime and smpi/test
    - InfiniBand network model added : Based on the works of Jerome Vienne (http://mescal.imag.fr/membres/jean-marc.vincent/index.html/PhD/Vienne.pdf )
    - When smpi/display_timing is set, also display global simulation time and application times
+   - Have smpirun, smpicc and friends display the simgrid git hash version on --git-version
  * Collective communications
    - SMP-aware algorithms are now dynamically handled. An internal communicator is created for each node, and an external one to handle communications between "leaders" of each node
    - MVAPICH2 (1.9) collective algorithms selector : normal and SMP algorithms are handled, and selection logic is based on the one used on TACC's Stampede cluster (https://www.tacc.utexas.edu/stampede/).

   * Bug fixes 
    - "Full" network optimization flag was broken since Surf++
    - Better handling of precision flags in maxmin
-   - Fix bug causing sometimes "Impossible" errors 
+   - Fix bug causing sometimes "Impossible" errors
+   - Properly pass cluster properties to included hosts
+  * 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
  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
+  * 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
