-SimGrid (3.9) NOT RELEASED; urgency=low
+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
+
+ 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()
+
+ SMPI:
+ * SMPI is now included directly in the libsimgrid as the windows
+ linker dont forces 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.
+ - 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 datatypes handling
+ * replace MPICH-1 test suite by the one from MPICH 3.0.4
+ * Add all missing Fortran bindings, SMPI should work with Fortran 90
+ (no privatization of global variables yet)
+
+ 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, 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 < 2*nominal bw
+ * Add a loopback_bw and loopback_lat options to cluster tag.

+SimGrid (3.9) stable; urgency=low
+
+ The Grasgory release: GRAS is really dead now.
+
+ * Complete overhaul of the internal host structures scheme.
+
+ GRAS:
+ * If you use GRAS, you should stay at SimGrid 3.5 (at most) since it
+ was considered as experimental and badly maintained since then.
+ * Keeping it was thus a trap to our potential users, that could take
+ it instead of MSG or SMPI by mistake despite is pity state.
+ * GRAS seems to have very few users (if any), and no one volunteered
+ to maintain it further. It also induces a lot of XBT code (for
+ portability sake), that must be maintained too.
+ * For all these reasons, we killed GRAS. If someone wants to revive it
+ in the future, don't cry, our git history still remembers of GRAS.
+
+ Documentation:
+ * Major overhaul. Merge our documentation again as time proved that
+ splitting it was really not helping our users.
+ * Further improve the developer documentation to help newcomers
+ hacking on SimGrid itself. The user documentation (and in
+ particular, the beginner documentation) is still in a sorry state.
SMPI:
* Now works on Windows too!
* Much more extensive test suite, from MPICH
+ SIMDAG:
+ * Add a new loader (SD_PTG_dotload) that creates a parallel task graph
+ (i.e., a DAG whose nodes are parallel tasks) from a dot file. Creates a
+ dynar of SD_TASK_COMP_PAR_AMDAHL and SD_TASK_COMM_MXN_1D_BLOCK tasks.
+ * Bug fix: let task be scheduled when the last dependency to be solved is
+ a control dependency.
+ * Remove SD_load_environment_script function.
+ Use the C sg_platf function if you want to declare a platform
+ programmatically.
+
MSG:
* New function: MSG_process_get_number()
+ * Old function documented: MSG_config()
+ * Remove MSG_load_platform_script function
+ Use the C sg_platf function if you want to declare a platform
+ programmatically.
+
+ SURF:
+ * Change the default value of the TCP_gamma constant (maximal size of TCP
+ congestion window) to a more realistic 4MiB value. If you notice changes in
+ your simulation results, you can fall back to the previous 20k tiny window
+ by adding --cfg=network/TCP_gamma:20000 on command line.
+ * (Hopefully) fix a bug wrt periodic availability and state traces
+ * Bug fix: use default values at start when first event in availability/state
+ trace is not at time 0.
+
+ PLATFORM:
+ * remove the "new_" part of function name sg_platf_new_trace_connect
+ (resulting in sg_platf_trace_connect), since it does not create
+ anything new
+
+ XBT:
+ * Kill synchronized dynars, and xbt_dynar_dopar(). We cannot think of a
+ use case where it's really mandatory, and maintaining it was a pain in
+ our code base.
+ * New: xbt_fifo_search(), search an item with a user-provided
+ comparison function instead of dumb pointer comparison.
+
+ LUA:
+ * Fix the lua deployment:
+ Use `simgrid.init_application()` before deployment instead of
+ `simgrid.msg_register_application()` after.
+
+ TRACING:
+ * Transfer the tracing files into the corresponding modules.
