+SMPI:
+ - 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
+
+Model-checker:
+ - Remove option 'model-check/record': Paths are recorded in any cases now.
+
+Fixed bugs (FG=FramaGit; GH=GitHub):
+ - FG#1: Broken link in error messages
+ - FG#2: missing installation documentation
+ - FG#3: missing documentation in smpirun
+ - FG#7: simple cmake call requires doxygen
+ - FG#10: Can not use MSG_process_set_data from SMPI any more
+ - FG#11: Auto-restart actors forget their on_exit behavior
+ - 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
+ - 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

+SimGrid (3.22) April 1. 2019
+
+The Easter Christmas Release (this one is somewhat late).
+
+Python:
+ - We are excited to introduce the SimGrid/S4U interface to your neighborhood
+ - Not complete yet: asynchronous activities (amongst others) are still missing
+ - Still ongoing: the interface may change in the future. We need more
+ testers! Please report any glitches.
+ - No new project using Java should start now. Please switch to Python.
+
+General:
+ - Some of the internal cleanups may lead to speed improvements:
+ - The hard limitation on the amount of simulated actors with
+ Java+Mac was removed. Now, the available memory is the only limit.
+ - Our refcounting was tidyied, leading to 10% speedups in some cases.
+ - We are still working on making our code robust to the actor kills
+ and hosts' churn. Things are improving, but it's not perfect yet.
+ - Replaced our own code to display a backtrace (that was forking addr2line)
