-SimGrid (3.23) NOT RELEASED (Release Target: June 21. 2019, 15:54 UTC)
+----------------------------------------------------------------------------
+
+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
+
+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.
+
+Model-Checker:
+ - Option model-checker/hash was removed. This is always activated now.
+
+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
+
+----------------------------------------------------------------------------
+
+SimGrid (3.23.2) July 8. 2019
+
+Documentation:
+ - Nicer introduction page.
+ - Migrate the "Deploy your application" page to the new doc.
+ - Move Java as a subtree of MSG.
General:
+ - Rename simgrid::TimeoutError to simgrid::TimeoutException.
+
+XBT:
+ - Drop xbt_dynar_sort_strings().
+
+Bugs:
+ - Really fix FG#26: Turning off a link should raise NetworkFailureException
+ - FG#27: Wrong exception thrown to wait_any when link is turned off
+ - GH#328: Java: Canceling multiple tasks in a single vm/host
+
+----------------------------------------------------------------------------
+
+SimGrid (3.23) June 25. 2019
+
+The Exotic Solstice Release.
+
+General:
+ - SunOS and Haiku OS support. Because exotic platforms are fun.
- Stop setting random seed with srand48() at initialization.
+ - Use addr2line as a fallback for stacktraces when backtrace is not available.
+ - Build option -Denable_documentation is now OFF by default.
+ - Network model 'NS3' was renamed into 'ns-3'.
+
+Python:
+ - Simgrid can now hopefully be installed with pip.
+
+S4U:
+ - wait_any can now be used for asynchronous executions too.
XBT:
- New log appenders: stdout and stderr. Use stdout for xbt_help.
- SMPI now reports support of MPI3.1. This does not mean SMPI supports all MPI 3 calls, but it was already the case with 2.2
- MPI/IO is now supported over the Storage API (no files are written or read, storage is simulated). Supported calls are all synchronous ones.
- MPI interface is now const correct for input parameters
+ - MPI_Ireduce, MPI_Iallreduce, MPI_Iscan, MPI_Iexscan, MPI_Ireduce_scatter, MPI_Ireduce_scatter_block support
+ - Fortran bindings for async collectives.
+ - MPI_Comm_get_name, MPI_Comm_set_name, MPI_Count support.
Model-checker:
- Remove option 'model-check/record': Paths are recorded in any cases now.
-
-Fixed bugs (GH=GitHub; FG=FramaGit):
+ - Remove option 'model-check/sparse-checkpoint': Checkpoints are now
+ always sparse. That's an immense gain in memory, and can even be
+ faster because of cache effects. So there is no need to clutter the
+ code to allow the user to go for the unefficient mode.
+
+Network models:
+ - Remove the lagrange-based models (Reno/Reno2/Vegas). The regular
+ models proved to be more accurate than these old experiments.
+
+Fixed bugs (FG=FramaGit; GH=GitHub -- Please prefer framagit for new bugs)
+ - FG#1: Broken link in error messages
+ - FG#2: missing installation documentation
+ - FG#3: missing documentation in smpirun
+ - FG#6: Python bindings not available on PyPI
+ - FG#7: simple cmake call requires doxygen
+ - FG#8: make python bindings an optional dependency
- FG#10: Can not use MSG_process_set_data from SMPI any more
- FG#11: Auto-restart actors forget their on_exit behavior
- - GH#133: Java : a process can run on a VM even if its host is off
+ - FG#12: -Denable_lto=OFF doesn't disable LTO
+ - FG#13: Installs unstripped file 'bin/graphicator'
+ - FG#14: Installs the empty directory 'doc/simgrid/html'
+ - FG#15: Setting -Denable_python=OFF doesn't disable the search for pybind11
+ - FG#17: Dead link in doc (pls_ns3)
+ - FG#20: 'tesh --help' should return 0
+ - FG#21: Documentation link on http://simgrid.org/ broken
+ - FG#22: Debian installation instruction are broken
+ - FG#26: Turning off a link should raise NetworkFailureException exceptions
+ - GH#133: Java: a process can run on a VM even if its host is off
+ - GH#320: Stacktrace: Avoid the backtrace variant of Boost.Stacktrace?
- GH#326: Valgrind-detected error for join() when energy plugin is activated
