+----------------------------------------------------------------------------
+
+SimGrid (3.20) Released June 24. 2018
+
+The proxy snake_case() release.
+
+S4U:
+ - The whole API is now using snake_case() instead of mixing it with camelCase.
+ Compatibility wrappers in place for one year.
+ - We took the opportunity to increase the consistency of the API.
+ Please report any remaining glitches.
+ - New function simgrid::s4u::Host::get_actor_count:
+ Returns the number of actors running on a specific host.
+
+SMPI:
+ - SMPI is now tested with ~45 proxy apps from various sources, with none or
+ only minor patching needed: check https://github.com/simgrid/SMPI-proxy-apps
+ - Replay: The replay file has been re-written in C++.
+ - Replay: Tags used for messages sent via MPI_Send / MPI_Recv are now
+ supported. They are stored in the trace and used when replayed.
+ - Basic support of MPI_Cancel. Robustness not guaranteed.
+ - Support of MPI_Win_allocate_shared, MPI_Win_shared_query, MPI_Comm_split_type
+ (only for MPI_COMM_TYPE_SHARED).
+ - New option: smpi/privatize-libs, to add external shared libs to be privatized
+ by SMPI. They will be copied locally and loaded separately by each process.
+ Example --cfg=smpi/privatize-libs:"libgfortran.so.3;libscalapack.so".
+ - Tracing: add tracing for MPI_Start, Startall, Testall, Testany
+ - Interception of getopt, getopt_long and getopt_long_only calls to avoid issues
+ with internal index optind with multiple processes. Only works if MPI_Init has
+ already been called.
+ - Fortran: SMPI builds a mpi.mod file which should allow use of "use mpi"
+ syntax without preprocessing tricks.
