+ - New and Backwards Compatibility break: 
+   SD_simulate_with_update (double how_long, xbt_dynar_t changed_tasks_dynar)
+   When one wants to get the list of tasks whose states have changed during a
+   simulation round, s/he has to allocate and free a dynar and use it as argument 
+   to this function. The former SD_simulate (double how_long) now returns void.

+ The Spring Release: continuous integration servers become green
  We fixed even the transient bugs on all target architectures:
    Linux (CentOS, Debian, Ubuntu, Fedora), Mac OSX (Mavericks, El Capitan)
    Windows, FreeBSD, NetBSD.

  SMPI
- - Bump our claim of support from MPI 1.1 to MPI 2.2. We don't support 100% of 
-   it, but it should be enough. Contact us if not.

+   naive and probably inaccurate)
  - New algorithm for SMPI_SHARED_MALLOC: global, where all blocks are
-   mapped onto a unique file.
- - Bugfix : smpirun was sometimes misusing hostfile when wrongly terminated
- - Fortran : cleanups, fixes, support of user-added operations
- - RMA : MPI_Accumulate are applied in correct order, and 
-   MPI_Win_complete or MPI_Win_post shouldn't miss messages anymore.
