+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.
+ - Use addr2line as a fallback for stacktraces when backtrace is not available.
+
+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
+
+Model-checker:
+ - Remove option 'model-check/record': Paths are recorded in any cases now.
+
+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

+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
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.
+ - Stop setting random seed with srand() at initialization.
XML
- In <host> and <peer>, 'availability_file' is now 'speed_file'.
The implementation was ways too messy to actually work, I guess.
SMPI:
- - Change the way SMPI_SAMPLE_* macros work to avoid invalidating cache
+ - Change the way SMPI_SAMPLE_* macros work to avoid invalidating cache
too often and provide more accurate timings.
- - Add -gdb and -lldb shortcuts to help debug MPI codes with smpirun
+ - 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_Request_get_status, MPI_Status_set_cancelled, MPI_Status_set_elements
- support
- - Basic implementation of generalized requests (SMPI doesn't

+ MPI_Iallreduce, MPI_Iscan, MPI_Iexscan, MPI_Ireduce_scatter,

+ - Basic implementation of generalized requests (SMPI doesn't
allow MPI_THREAD_MULTIPLE) : MPI_Grequest_complete, MPI_Grequest_start
XBT:
the pthread backend. It caused some weird deadlock or behavior
depending on the pthread implementation. [AL]
* Bugfix: get the exceptions raised in the simulator repport where

SURF:
* Bugfix: Do repport the error when two non-connected hosts try to
* New! Exception handling with setjmp or such (code from OSSP ex) [MQ]
This deprecates the xbt_error_t mechanisms.
It modifies (simplifies) all XBT and GRAS API.

within MSG and masked with existing error handling facilities)
