 SimGrid (3.15) UNRELEASED; urgency=low
 
- The Ever Green Release. 
+ 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.

  - New: MSG_process_ref/unref(). Fiddle with the process refcounting.
  - Renamed MSG_energy_plugin_init() -> MSG_host_energy_plugin_init()
    to make room for the upcoming network energy plugin.
- - Drop MSG_host_get_current_power_peak: dupplicates MSG_host_get_speed
+ - Drop MSG_host_get_current_power_peak: duplicates MSG_host_get_speed

+ - Partial bug fix in initialization. SimGrid flags on command line were 
+   consumed at C level but stayed in the original Java String[] args. 
+   This could mess users' args[i] if SG flags were not put at the end of
+   the command line.
+   The SimGrid flags are now removed from the Java arguments. However, 
+   the number of arguments REMAINS UNCHANGED. It is then UNSAFE to test
+   if args.length is greater than the number of YOUR OWN ARGUMENTS. 
+   It might be if you have --log or --cfg flags in the command line.

  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.
+ - Major C++ rewrite ongoing (SMPI used to be C compiled in C++). 
+   This can break codes using SMPI internals (from private.h instead of the public smpi.h).
+ - 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.
+ - MPI_Win_lock/unlock support added (as for all RMA, implementation is 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.

  - Replace implementation of MPI_Bcast "scatter followed by rdb allgather"
    algorithm by a non failing one from mpich.
