-SimGrid (3.10) NOT RELEASED; urgency=low
-
- XBT:
- * Our own implementation of getline is renamed xbt_getline, and gets
-   used even if the OS provide a getline(). This should reduce the
-   configuration complexity by using the same code on all platforms.
- * new xbt_cfg_elm_boolean type
+SimGrid (3.10pre1) unstable; urgency=low
 
  Java:
  * Reintegrate Java to the main archive as desynchronizing these
    package is not acceptable anymore (Java is now considered stable)
+ * Add explicit synchronization facilities through semaphores
  * Bugfix: Task.setDataSize() only changed the C world, not the value
    cached in the Java world
 
+ MSG:
+ * Dramatically change the way files are handled. API and internals changed, but
+   this part of MSG was not considered as production grade either.
+ * Add explicit synchronization facilities through semaphores
+ * Add a new function MSG_host_get_process_list()
+ * Preliminary DVFS support (see /examples/msg/energy for details)
+
  SMPI:
- * SMPI is not built as a separate library anymore, it's now included in
-   libsimgrid.
+ * SMPI is now included directly in the libsimgrid as the windows
+   linker doesn't force us on splitting it anymore.
  * Improvements of the SMPI replay tool:
    - Most of the collective communications are now rooted in the same process as
      in the original application.
-   - Traces now rely on the same MPI datatype as the application (MPI_BYTE was
-     used until now). Multiple datatypes can now be used in a trace.
+   - Traces now rely on the same MPI data type as the application (MPI_BYTE was
+     used until now). Multiple data types can now be used in a trace.
    - The replay tool now supports traces produce either by TAU or a modified
      version of MPE.
    - Bug Fix: the compute part of the reduce action is now taken into account.
+ * smpirun generates the hostfile if needed (with given hostcount and platform)
+ * Integration of more than 100 STAR-MPI, MPICH, OpenMPI collective algorithms
+   - allows to select one in particular with --cfg=smpi/coll_name:algorithm
+   - allows to use the decision logic of OpenMPI(1.7) or MPICH(3.0.4) by setting
+     --cfg=smpi/coll_selector:(mpich/ompi)
+ * Support for new functions : MPI_Issend, MPI_Ssend, Commutative operations in
+   Reduce
+ * Add a --cfg:tracing/smpi/internals option, to trace internal communications
+   happening inside a collective SMPI call.
+ * Fix the behavior of complex data types handling
+ * replace MPICH-1 test suite by the one from MPICH 3.0.4. Can be built using
+   enable_smpi_MPICH3_testsuite flag in cmake. Run with ctest.
+ * Add all missing Fortran bindings, SMPI should work with Fortran 90
+   (no privatization of global variables yet)
+
+ Model-Checking;
+ * Verification of liveness properties is now available for SMPI applications
+   (in addition to MSG applications)
+ * Bugged examples using SMPI in examples/smpi/mc/
+ * Add --cfg=model-check/visited option. Allows the verification of infinite
+   programs. Detection of loops in the execution thanks to the system state
+   comparison and reduction of the state space to explore. Can be combined with
+   DPOR for safety properties.
+
+ SimDag:
+ * Allow to change SimGrid configuration (see --help) within the code
+   thanks to SD_config() as it can be done in MSG.
+ * Add a new function SD_task_set_amount() upon user request.
 
  PLATFORM:
- * Handle units for values (10ms, 10kiloflops, 10Bps, ...)
- * Remove rule based routing (no more pcre dependency)
+ * Handle units for values (10ms, 10kiloflops, 10Bps, 1GB, ...)
+ * Remove rule based routing (no more PCRE dependency)
+ * Add a limiter_link option to cluster tag, to specify a maximum reachable
+   bandwidth in fullduplex mode when it is less than twice the nominal bandwidth.
+ * Add a loopback_bw and loopback_lat options to cluster tag.
+ * Fix the peer tag that could not be mixed with other AS within a Vivaldi
+   routing. Now peers are encapsulated in an AS and have their own private
+   router but this is transparent.
+
+ XBT:
+ * Our own implementation of getline is renamed xbt_getline, and gets
+   used even if the OS provide a getline(). This should reduce the
+   configuration complexity by using the same code on all platforms.
+ * new xbt_cfg_elm_boolean type
+ * Allow to disable SimGrid cleanups at exit from command line option.
+   There are situations where one may want a simulation to end with an exit.
+   Unfortunately, calling exit may cause SimGrid to segfault, which is quite
+   annoying when scripting around the simulator. Adding a
+   --cfg=clean_atexit:yes allows to circumvent this issue.
