+SimGrid (3.17) UNRELEASED (release target: September 22 2017)
+
+ S4U
+ - start and forget about isend comms with detach()
+
+SimGrid (3.16) Released June 22. 2017.
+
+ The Blooming Spring Release: developments are budding.
+
+ 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, with the correct sharing (unless you overcommit)
+ BUG: vCPU overcommitting still leads to buggy sharing, though. WIP.
+
+ Energy
+ - New function to update the consumption of all hosts at once.
+ - Fix the model for multi-core hosts, linear in the amount of busy
+ cores with an abnormality for pIdle (see paper).
+ BUG: Still not satisfactory for ptask on mono-cores.
+
+ 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.
+ - Behind the scene, ActivityImpl are now automatically refcounted.
+ Removing this nasty bottleneck will greatly simplify our internals.
+
+ 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.
