 S4U:
  - Barrier::wait returns SG_BARRIER_SERIAL_THREAD for (only) one actor
    for consistency with pthread_barrier_wait()
+ - Host::get_englobing_zone() returns the englobing netzone
+ - Actor::on_destruction is now called in the destructor
+   Actor::on_termination new signal called when the actor terminates
+   its code.
+ - 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:
+ - Improved the usability of ns-3. Several bugs were ironed out.
+ - 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.
 
 MSG:
  - convert a new set of functions to the S4U C interface and move the old MSG

 SMPI:
  - Fortran bindings for DVFS have been removed.
+ - Add support for MPI_Irsend, MPI_Rsend, MPI_Rsend_init, MPI_Bsend, 
+   MPI_Ibsend, MPI_Bsend_init, MPI_Buffer_attach, MPI_Buffer_detach
+ - SMPI can now be selected by cmake's find_module(MPI) with
+   MPI_C_COMPILER, MPI_CXX_COMPILER, MPI_Fortran_COMPILER variables.
+ - Add support for MPI Errhandlers in Comm, File or Win. Default errhandler is now
+   MPI_ERRORS_ARE_FATAL, so codes which were sending warnings may start failing.
 
 Model-Checker:
+ - Use the included xxHash as an hash implem when C++14 is usable.
  - Option model-checker/hash was removed. This is always activated now.
+ - New option smpi/buffering controls the MPI buffering in MC mode.
+ - MPI calls now MC_assert() that no MPI_ERR_* code is returned. 
+   This is useful to check for MPI compliance.
 
 XBT:
  - xbt_mutex_t and xbt_cond_t are now marked as deprecated, a new C interface
    on S4U is already available to replace them by sg_mutex_t and sg_cond_t. 
 
-Bugs:
+Fixed bugs (FG#.. -> framagit bugs; FG!.. -> framagit merge requests):
  - FG#28: add sg_actor_self (and other wrappers on this_actor methods)
  - FG#29 and FG#33: provide a new C API to mutexes and condition variables 
  - FG#30: convert MSG_process_{un}ref to sg_actor_{un}ref
+ - FG#31: per-actor data
  - FG#34: SG_BARRIER_SERIAL_THREAD?
+ - FG#35: model-checker does not like buster-produced binaries
+ - FG!13: MC: complete workaround in the error msg seen on modern systems
+ - FG!15: execute_flops now logs compute
+ - FG!16: Fix the ns-3 bindings when several flows are simultaneously finishing
+ - FG!17: ns-3: unblock the right number of communications + others issues
+ - FG!18: Improving the performance of the ns-3 bindings
