+ - Remove the surf module. It was replaced by the kernel/models module, and that 
+   refactoring took almost 10 years to properly complete.

 
 S4U:
  - Activity::set_remaining() is not public anymore. Use for example
    Comm::set_payload_size() to change the size of the simulated data.
  - New function: Engine::flatify_platform(), to get a fully detailed vision of the
    configured platform.

 MPI:
  - New option smpi/barrier-collectives to add a barrier to some collectives
    to detect dangerous code that /may/ work on some MPI implems.
