+SimGrid (3.22) NOT RELEASED (Release Target: December 21. 2018, 22:23 UTC)
+
+Java:
+ - Expose host load plugin: loadInit, getCurrentLoad, getComputedFlops, getAvgLoad
+
+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.
+
+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.
+
+XBT:
+ - Drop sg_cmdline. Please use xbt_cmdline instead.
+ - 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.
+
+Fixed bugs:
+ - #261: Document the parameters of parallel execution's constructor
+ - #314: SMPI args internal cleanup
+ - #316: Fix a bug related to the CPU utilization of multi-core VM

+
+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.
+
+S4U new features:
+ - Fully reimplement auto_restart mechanism that was utterly broken
+ (fix #22, #131 and #281 that were all very related)
+ - Implement semaphores (fix #303 and #291)
+ - When creating an actor from a function and its parameters,
+ move-only parameters are not allowed anymore, as it would prevent
+ the actor to be restartable if its parameters are consumed on run.
+ - s4u::Io: IOs go asynchronous as activities. New methods in s4u::Storage:
+ - io_init(sg_size_t, s4u::Io::OpType) to create a READ or WRITE asynchronous
+ IO operations that can be started, waited for, or canceled as a regular
+ activity.
+ - read_async(sg_size_t) and write_async(sg_size_t) which are wrappers on
+ io_init() + start()
