+SimGrid (3.22) NOT RELEASED (Release Target: December 21. 2018, 22:23 UTC)
+
+Java:
+ - Process termination which was broken at version 3.21 has been repaired.
+ - Expose host load plugin: loadInit, getCurrentLoad, getComputedFlops, getAvgLoad
+ - Hide the examples into examples/deprecated. New users should use Python.
+
+Core:
+ - Replace our own code to display a backtrace (that was forking addr2line)
+ with the Boost.Stacktrace library.
+ You won't see your backtraces without this optional dependency.
+ - Bump cmake dependency to 3.5 (provided by Ubuntu 16.04).
+
+MSG:
+ - Drop MSG_process_create_from_stdfunc() from the API.
+ This C++ function was a pimple in the C API, made necessary at some
+ point by the Java bindings. This is fixed now.
+ - Hide the examples into examples/deprecated. New users should use S4U.
+
+XBT:
+ - Drop sg_cmdline. Please use xbt_cmdline instead.
+ - Drop the C xbt_os_mutex_t; Use the C++11 std::mutex.
+ - Drop the C xbt_os_sem_t; Use the C++ xbt::OsSemaphore.
+ OsSemaphore is implemented in a portable way with C++11 threads.
+ This should allow much more threads to be created at the same time,
+ allowing Mac and Java users to simulate many more actors.
+ - Implement the 'thread' factory with std::thread instead of xbt ones.
+ It is not possible to set the stack size with threads anymore, but
+ -fsplit-stack is the way to go nowadays when using threads.
+ - Drop the xbt_os_thread_t module (now unused)
+ - Drop xbt_ex_display(), use simgrid::xbt::log_exception() instead.
+ - Drop cunit, use Catch2 instead.
+
+XML
+ - In <host> and <peer>, availability_file is now speed_file.
+ XML file version remains 4.2 since old files are still compatible.
+
+Fixed bugs:
+ - #132: Java : a process can not shut down its own host
+ - #261: Document the parameters of parallel execution's constructor
+ - #300: [s4u] BarrierPtr is missing
+ - #314: SMPI args internal cleanup
+ - #316: Fix a bug related to the CPU utilization of multi-core VM
+ - #318: Invalid trace file when using option --cfg=tracing/smpi/display-sizes:yes

+----------------------------------------------------------------------------
+
+SimGrid (3.21) October 3. 2018
+
+The Restarting Documentation (TRD) Release.
+
+Documentation:
+ - Convert the user manual to Sphinx for improved usability.
+ Unstable version now hosted on https://simgrid.frama.io/simgrid
+ Many glitches remain; stay tuned.
+ - Restrict the Doxygen reference API to the installed header files.
+ (documenting all internals this way is overkill + doxygen scales badly)
+ - New tutorial on S4U (highly inspired from the old MSG one, but with
+ a git repository to fork as a starting point, and a docker image)
+ - Started but not finished a SMPI tutorial inspired from the JLPC'14 one.
+ - The Developper manual is still to be converted (not compiled until then)
+ - Some parts are still missing in this conversion (such as the
+ platform and deployment sections) while others were blindly converted
+ and would need more love (such as the configuration flags).
+ Things will certainly further improve in the future releases.
