+SimGrid (3.16) UNRELEASED
+
+ 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>
+   - <zoneZoute> an 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
+
+ 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
+  - Support for sparse privatized malloc with SMPI_PARTIAL_SHARED_MALLOC()
+
+ 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.

    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)
+ - MPI_Win_lock/unlock, MPI_Get_accumulate 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 small file using some system magic.
