+SimGrid (3.23) NOT RELEASED (Release Target: June 21. 2019, 15:54 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.
+XBT:
+ - Drop xbt_dict_dump.
 
-Core:
- - Replace our own code to display a backtrace (that was forking addr2line)
+Fixed bugs (GH=GitHub; FG=FramaGit):
+ - FG#10: Can not use MSG_process_set_data from SMPI any more
+ - GH#326: Valgrind-detected error for join() when energy plugin is activated

+SimGrid (3.22) April 1. 2019
+
+The Easter Chrismas 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)
    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).
+ - Stop setting random seed with srand() at initialization.
+
+XML
+ - In <host> and <peer>, 'availability_file' is now 'speed_file'.
+   XML file version remains 4.2 since old files are still compatible.

 MSG:
  - Drop MSG_process_create_from_stdfunc() from the API.

  - Hide the examples into examples/deprecated. New users should use S4U.
  - MSG_process_create and MSG_process_attach now crash if the host used
    to run this process is off.
+ - Fix the protype of MSG_process_on_exit()
+   Now use (int,void*) callbacks instead of (void*,void*) ones.
+   The implementation was ways too messy to actually work, I guess.
+
+SMPI:
+ - Change the way SMPI_SAMPLE_* macros work to avoid invalidating cache
+   too often and provide more accurate timings.
+ - Add -gdb, -lldb, and -vgdb shortcuts to help debug MPI codes with smpirun
+ - MPI_Alltoallw support
+ - Partial MPI nonblocking collectives implementation: MPI_Ibcast, MPI_Ibarrier,
+   MPI_Iallgather, MPI_Iallgatherv, MPI_Ialltoall, MPI_Ialltoallv, MPI_Igather,
+   MPI_Igatherv, MPI_Iscatter, MPI_Iscatterv, MPI_Ialltoallw, MPI_Ireduce,
+   MPI_Iallreduce, MPI_Iscan, MPI_Iexscan, MPI_Ireduce_scatter,
+   MPI_Ireduce_scatter_block, with fortran bindings.
+ - MPI_Request_get_status, MPI_Status_set_cancelled, MPI_Status_set_elements
+   support, MPI_Comm_get_name, MPI_Comm_set_name
+ - Basic implementation of generalized requests (SMPI doesn't
+   allow MPI_THREAD_MULTIPLE) : MPI_Grequest_complete, MPI_Grequest_start
 
 XBT:
  - Drop sg_cmdline. Please use xbt_cmdline instead.

+Kernel:
+ - Many cleanups in the kernel::activity namespace. This was long
