 SimGrid (3.16) UNRELEASED
 
-SimDag
- - 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.
+ Portability status:
+  - FreeBSD: Disable SMPI mmap privatization, switch automatically to dlopen.
+  - Mac, BSD: dlopen+thread broken, switch automatically to raw contexts.
+  - Java JAR file should be finally fully working on Mac OSX too.
+
+ XML platforms: Switch to platform v4.1 format.
+ * This is (mainly) a backward compatible change: v4 are valid v4.1 files
+   - <zone> can be used as a synonym for the now deprecated <as>
+   - <zoneRoute> can be used as a synonym for the now deprecated <asroute>
+   - <bypassZoneRoute> an be used as a synonym for the now deprecated <bypassAsRoute>
+   - <actor> can be used as a synonym for the now deprecated <process>
+   - state_file and avail_file periodicity is now easier to express
+     (check the documentation) the old behavior should still work.
+ * Storage: not backward compatible, but it seems that nobody ever used it
+   - Remove attribute 'content_type' of <storage_type>: was never used
+   - Make attribute 'model' of <storage_type> optional: for future usage
+   - Remove Bconnection model property: was never (in)validated. Replaced by
+      the maximum of the read and write bandwidth as a resource constraint.

+ SimDag
+  - 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.
+
+ Virtual Machines
+  - Allow multicore VMs, along with the correct sharing computations
+
+ Energy
+  - New function to update the consumption of all hosts at once.
+
+ MSG
+  - The netzone are now available from the MSG API.
+    The old names still work, but are now deprecated.
 
  SMPI
   - New algorithm to privatize globals: dlopen, with dynamic loading tricks
   - New option: smpi/keep-temps to not cleanup temp files
+  - New option : smpi/shared-malloc-blocksize . Relevant only when global shared 
+    mallocs mode is used, allows to change the size of the fake file used
+    (default 1MB), to potentially limit the number of mappings for large runs.
+  - Support for sparse privatized malloc with SMPI_PARTIAL_SHARED_MALLOC()
+  - Fortran ifort and flang compilers support
+  - New RMA calls supported (experimental) :
+      - MPI_Win_allocate, MPI_Win_create_dynamic, MPI_Win_attach
+      - MPI_Win_detach, MPI_Win_set_info, MPI_Win_get_info
+      - MPI_Win_lock_all, MPI_Win_unlock_all, MPI_Win_flush
+      - MPI_Win_flush_local, MPI_Win_flush_all, MPI_Win_flush_local_all
+      - MPI_Op_commutative, MPI_Fetch_and_Op, MPI_Compare_and_swap
+      - MPI_Rput, MPI_Rget, MPI_Raccumulate, MPI_Rget_accumulate
+
+ S4U
+  - New: this_actor::isMaestro() returns whether we are in kernel mode.
 
- XBT/Replay:
-  - New function xbt_replay_action_get():
+ XBT
+  - Replay: New function xbt_replay_action_get():
     Retrieve the function previously associated to an event type.
+  - DROPPED FUNCTION: xbt_str_varsubst()
+  - DROPPED MODULE: strbuff. We don't need it anymore.
+  - DROPPED MODULE: matrix. We don't need it anymore.
+  - DROPPED MODULE: lib. We don't need it anymore.
