+SimGrid (3.24.1) NOT RELEASED YET (v3.25 expected December 22. 2029, 04:19 UTC)
+
+Fixed bugs (FG#.. -> framagit bugs; FG!.. -> framagit merge requests):
+ - GH#31: [MC] please provide an option to make MPI_Send asynchronous
+ - GH#305: Unscheduled tasks are still excuted
+ - FG!19: Removing RngStream
+
+----------------------------------------------------------------------------
+
+SimGrid (3.24) October 9. 2019
+
+The Clean Disk Release.
+
+S4U:
+ - Introduce a s4u::Disk interface to manage the newly introduced <disk>
+ tag. s4u::Disk is called to supplant s4u::Storage in a near future. It
+ thus becomes the default resource to execute I/O operations. Examples
+ and the file system plugin have been modified to use disks instead of
+ storage elements. Storage can still be used but is doomed to disappear.
+ Users are thus adviced to update their simulators accordingly.
+ - Barrier::wait returns SG_BARRIER_SERIAL_THREAD for (only) one actor
+ for consistency with pthread_barrier_wait()
+ - Host::get_englobing_zone() returns the englobing netzone
+ - Actor::on_destruction is now called in the destructor
+ Actor::on_termination new signal called when the actor terminates
+ its code.
+ - Global signals are now part of the Engine:
+ - on_platform_creation: after config settings, before the XML parsing
+ - on_platform_created: right after the XML parsing
+ - on_time_advance: each time the clock advances
+ - on_simulation_end: after simulation, before cleanups
+ - on_deadlock: as the name implies.
+ - C bindings:
+ - sg_{actor,host,link}_{data,data_set}() now all exist.
+ Use them to attach user data to the object and retrieve it.
+
+Models:
+ - Introduce an experimental Wifi model. It sounds reasonable
+ according to the state of the art, but it still has to be properly
+ validated, at least against ns-3 if not against reality.
+ - Improved the usability of ns-3. Several bugs were ironed out.
+ - host_energy: Wattage was expressed as 'idle:oneCore:allCores'.
+ It is now expressed as 'idle:epsilon:allCores' to properly model the
+ consumption of non-whole tasks on mono-core hosts. More info in the doc.
+
+MSG:
+ - convert a new set of functions to the S4U C interface and move the old MSG
+ versions to legacy (MSG_process_self*, MSG_process_{un}ref, ...)
+
+SMPI:
+ - Fortran bindings for DVFS have been removed.
+ - Add support for MPI_Irsend, MPI_Rsend, MPI_Rsend_init, MPI_Bsend,
+ MPI_Ibsend, MPI_Bsend_init, MPI_Buffer_attach, MPI_Buffer_detach
+ - SMPI can now be selected by cmake's find_module(MPI) with
+ MPI_C_COMPILER, MPI_CXX_COMPILER, MPI_Fortran_COMPILER variables.
+ - Add support for MPI Errhandlers in Comm, File or Win. Default errhandler is now
+ MPI_ERRORS_ARE_FATAL, so codes which were sending warnings may start failing.
+ - trace-call-location can be used with TI traces, and replayed, and is compatible
+ with smpi/comp-adjustment-file.
+ - sleep events are now correctly traced/replayed.
+ - Default for trace-call-location is now to use file names and not full paths.
+ To revert to previous behaviour (in case of collision of filenames), option
+ "smpi/trace-call-use-absolute-path" can be set to yes.
+
+Model-Checker:
+ - Use the included xxHash as an hash implem when C++14 is usable.
+ - Option model-checker/hash was removed. This is always activated now.
+ - New option smpi/buffering controls the MPI buffering in MC mode.
+ - MPI calls now MC_assert() that no MPI_ERR_* code is returned.
+ This is useful to check for MPI compliance.
+
+Documentation:
+ - New section on plugins: how to define a new one, and existing ones.
+
+XBT:
+ - xbt_mutex_t and xbt_cond_t are now marked as deprecated, a new C interface
+ on S4U is already available to replace them by sg_mutex_t and sg_cond_t.
+
+XML:
+ - Introduce the <disk> tag as a replacement of the <storage>, <storage_type>,
+ and <mount> tags. The rationale is finish to decouple what should be handle
+ by SimGrid kernel (i.e., resources and activities) from plugins built in
+ user space (e.g., the file system plugin). This new tag currently accepts
+ only three attributes (id, read_bw, and write_bw). All the other information
+ that was declared with the storage related tags now has to be expressed as
+ properties. An example of platform using this new tag is available at
+ examples/platforms/hosts_with_disks.xml
+
+tesh:
+ - 'expect signal' can now accept more than one potential signal.
+
+Fixed bugs (FG#.. -> framagit bugs; FG!.. -> framagit merge requests):
+ - FG#28: add sg_actor_self (and other wrappers on this_actor methods)
+ - FG#29 and FG#33: provide a new C API to mutexes and condition variables
+ - FG#30: convert MSG_process_{un}ref to sg_actor_{un}ref
+ - FG#31: per-actor data
+ - FG#34: SG_BARRIER_SERIAL_THREAD?
+ - FG#35: model-checker does not like buster-produced binaries
+ - FG!13: MC: complete workaround in the error msg seen on modern systems
+ - FG!15: execute_flops now logs compute
+ - FG!16: Fix the ns-3 bindings when several flows are simultaneously finishing
+ - FG!17: ns-3: unblock the right number of communications + others issues
+ - FG!18: Improving the performance of the ns-3 bindings
+ - GH#189: Energy consumption of parallel tasks
+ - GH#219: Error in the throughput of TCP transfer
+ - GH!330: Minor polishing of English: Configuring_Simgrid
+ - GH!331: Fix a doc error about actors (Tutorial_algorithms)
+ - GH!332: Add '-O0' flag for: cmake -DCMAKE_BUILD_TYPE=Debug
+ - GH!334: Rework energy plugin, again
