SimGrid (3.23.3) NOT RELEASED YET (v3.24 expected September 23. 7:50 UTC)
+S4U:
+ - 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.
+
+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
+ - 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.
+
+Model-Checker:
+ - 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.
+
+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.
+
+Bugs:
+ - 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#34: SG_BARRIER_SERIAL_THREAD?
+ - FG#35: model-checker does not like buster-produced binaries
