 SimGrid (3.15) UNRELEASED; urgency=low
 
+ The Ever Green Release. 
+ We fixed even the transient bugs on all target architectures:
+   Linux (CentOS, Debian, Ubuntu, Fedora), Mac OSX (Mavericks, El Capitan)
+   Windows, FreeBSD, NetBSD.
+
  - Rename NetCards to NetPoints.
    This was intended to help NS3 users, but that's not a netcard.
    That's a point in the routing algorithm, let's avoid wrong simplifications.
 
  MSG
- - New function: MSG_process_yield()
+ - New: MSG_process_yield(). Stop and yield to other processes.
+ - New: MSG_process_daemon(). Daemon processes are automatically killed 
+   when the last non-daemon process terminates
+ - 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
 
  Java
  - Ensure that an actor can kill itself with Process::exit()

  S4U
  - New callbacks:
-   - simgrid::s4u::onPlatformCreated: right before the simulation starts
-   - simgrid::s4u::onSimulationEnd: right after the main simulation loop
+   - s4u::onPlatformCreated: right before the simulation starts
+   - s4u::onSimulationEnd: right after the main simulation loop
+   - s4u::onTimeAdvance: right after a clock change (time is discrete)
+   - s4u::Host::onSpeedChange: when the pstate is changed, or when an
+     event from the availability_file changes the avail speed.
  - Links are now usable from s4u
+ - New: Engine::hostList() and Engine::hostCount(). Still clumsy.
+ - Drop Host::getPstateSpeedCurrent() which dupplicates Host::speed()
+
+ SimDag
+ - Backwards Compatibility breaks
+    - The SD_route_get_list and SD_route_get_size functions have been removed. 
+      They are replaced by the unique 
+         void sg_host_route(sg_host_t src, sg_host_t dst, xbt_dynar_t links)
+      The route from src to dst is built in the links dynar whose size can 
+      be obtained with xbt_dynar_length.
+    - The SD_route_bandwidth and SD_route_latency functions have been replaced by
+        sg_host_route_bandwidth and sg_host_route_latency. 
+      Macros ensure the backwards compatibility, but you should fix your code
+
+ SMPI
+ - Major C++ rewrite ongoing (SMPI used to be C compiled in C++). This can break codes that were using internals of SMPI (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.
+ - 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.
+ - Better support for MPI_IN_PLACE
+ - Support for MPI_Win attrs and keyvals.
+ - Support MPI_Comm_group_create, MPI_Type_size_x
+ - MPI ops should be properly applied to all allowed types
+ - Replace implementation of MPI_Bcast "scatter followed by rdb allgather"
+   algorithm by a non failing one from mpich.
+
+ XBT
+ - Kill the fifo data container: we don't use it anymore.
+
+ XML
+ - A <cluster> can now be created with different speed values to represent pstates.
+   see examples/platforms/energy_cluster.xml for an example.
