+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.
- The Ever Green Release.
+ 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.

+SimGrid (3.15) stable; urgency=low
+
+ The Spring Release: continuous integration servers become green
We fixed even the transient bugs on all target architectures:
Linux (CentOS, Debian, Ubuntu, Fedora), Mac OSX (Mavericks, El Capitan)
Windows, FreeBSD, NetBSD.
the number of arguments REMAINS UNCHANGED. It is then UNSAFE to test
if args.length is greater than the number of YOUR OWN ARGUMENTS.
It might be if you have --log or --cfg flags in the command line.
+ - Fix numerous memleaks all around the place. In particular, around VMs.
S4U
- New callbacks:
Macros ensure the backwards compatibility, but you should fix your code
SMPI
- - Major C++ rewrite ongoing (SMPI used to be C compiled in C++). This can break codes that were using internals of SMPI (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 file.
- - Bugfix : smpirun was sometimes misusing hostfile when wrongly terminated
- - Fortran : cleanups, fixes, support of user-added operations
- - RMA : MPI_Accumulate are applied in correct order, and
- MPI_Win_complete or MPI_Win_post shouldn't miss messages anymore.

- Better support for MPI_IN_PLACE
- Support for MPI_Win attrs and keyvals.
- Support MPI_Comm_group_create, MPI_Type_size_x
- A <cluster> can now be created with different speed values to represent pstates.
