 SimGrid (3.18) NOT RELEASED YET (target: December 24 2017)
 
- S4U
+ S4U New features
+ - s4u::onDeadlock() signal, run before stopping the simulation.
+ - s4u::Exec: asynchronous executions (abstraction of background
+   threads)
+ - s4u::Host->getLoad() returns the achieved speed in flops/s
+
+ S4U API changes
  - Link::name() is deprecated and will be removed in v3.21, use
    Link::getCname() instead.
  - Mailbox::getName() changed to return a std::string, use
    Mailbox::getCname() instead to get a char*.
  - Storage::getName() changed to return a std::string, use
    Storage::getCname() instead to get a char*.
- - simgrid::s4u::allStorages() becomes
-   simgrid::s4u::getStorageList(whereTo) to have both allocation
-   and deallocation of the map in user space.
+ - s4u::allStorages() becomes s4u::getStorageList(whereTo) 
+   to have both allocation and deallocation of the map in user space.
 
  MSG
- - Deprecate MSG_task_get_flops_amount(). Its semantic was weird:
-    before the start it returned the total amount of flops;
-    after it returned the ratio of remaining work. Split it:
-   MSG_task_get_initial_flops_amount() for first behavior
-   MSG_task_get_remaining_work_ratio() for the second one.
-   This fixes GitHub's #223 using PR #237. Thanks Michael Mercier.
+ - Forbid the use of MSG_task_get_flops_amount() on parallel tasks:
+   The amount of flops remaining to do is a vector, not a scalar.
+ - Introduce MSG_task_get_remaining_work_ratio(), which does what its
+   name implies on both sequential and parallel tasks.
+ - Both changes fix GitHub's #223 using PR #237 as a basis.
+   Thanks Michael Mercier.
 
  SURF
  - LMM stuff moved to its own namespace: simgrid::kernel::lmm.
  - Renamed LMM classes (e.g. s_lmm_system_t -> System).
 
+ Virtual Machines
+ - Live migration is getting moved to a plugin. Dirty page tracking is
+   the first part of this plugin. This imply that VM migration is now
+   only possible if one this function is called :
+    - C/MSG: MSG_vm_live_migration_plugin_init() 
+    - C/C++: sg_vm_live_migration_plugin_init()
+    - Java:  Msg.liveMigrationInit()
+   For C and C++, "simgrid/plugins/live_migration.h" also has to be 
+   included.
+
  XBT
  - Define class simgrid::xbt::Path to manage file names.
  - Removed unused functions:
