+SimGrid (3.23) NOT RELEASED (Release Target: June 21. 2019, 15:54 UTC)
 
-The Sneaky Release.
+General:
+ - Stop setting random seed with srand48() at initialization.
+
+XBT:
+ - New log appenders: stdout and stderr. Use stdout for xbt_help.
+ - Drop xbt_dict_dump.
+
+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
+
+Fixed bugs (GH=GitHub; FG=FramaGit):
+ - 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
+ - GH#326: Valgrind-detected error for join() when energy plugin is activated

+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 a bit in the future (please
-   report any glitches), but it seems rather fast and reliable already. 
- - Forget about Java now (and soon about C++)
-
-Core:
- - Replace our own code to display a backtrace (that was forking addr2line)
+ - 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).
