 SimGrid (3.18) NOT RELEASED YET (target: December 24 2017)
 
- S4U
- - Link::name() is deprecated and will be removed in v3.21, use instead
-   Link::getCname().
- - Mailbox::getName() changed to return a std::string, use instead
-   Mailbox::getCname() to get a char*.
- - Storage::getName() changed to return a std::string, use intead
-   Storage::getCname() to get a char*.
+ 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*.
+ - s4u::allStorages() becomes s4u::getStorageList(whereTo) 
+   to have both allocation and deallocation of the map in user space.
+
+ MSG
+ - 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:
    - xbt/file.h: xbt_basename(), xbt_dirname(), xbt_getline()
+   - xbt/graph.h: xbt_graph_edge_get_length(), xbt_graph_edge_set_length,
+       xbt_graph_export_graphviz()
    - xbt/str.h: xbt_str_join()
+ - Remove unused datatypes:
+   - xbt/heap.h: use std::priority_queue or boost::heap instead
+   - xbt/swag.h: use boost::intrusive::list instead
+
+ PLUGINS:
+ - New link_energy plugin for the consumption of the links.
+ - All of the operations on files and storage contents have been
+   packaged into a plugin (src/plugins/file_system). The current
+   public interface can be found in
+   include/simgrid/plugins/file_system.h
+   To use these functions you now have to initialize the plugin by
+   calling MSG_storage_file_system_init() just after calling
+   MSG_init() or sg_storage_file_system_init() just after creating
+   the Engine.
+
+ XML
+ - Remove the undocumented/untested tag <include>
+
+ TRACE
+ - Remove viva specific tracing as the tool is no longer maintained
+
+ Fixed bugs:
+ - #248: Kill of finished processes leads to segfault
+ - #240: xbt_cond_wait_timeout should gracefully return for C apps
+ - #239: please implement signal s4u::onDeadlock()
+ - #230: segfaults when exit() without run() 
+ - #225: s4u::Actor::kill() doesn not really kill victims in a join()
+ - #223: MSG_task_get_flops_amount() not working with parallel tasks
+ - #222: Actor::kill() doesn't really kill and segfaults 
+ - #221: odd LMM warning when killing an actor 
+ - #120: Memory leak when the processes are forcefully killed
