 TRACE
  - Change --cfg=tracing/msg/vm to --cfg=tracing/vm as virtual machine
-   behavior tracing is no longer limited to MSG 
+   behavior tracing is no longer limited to MSG
+
+MSG
+ - The deprecation of MSG is ongoing. A lot of functions are now simple
+   wrappers on the C API of S4U. All these wrappers (and their S4U counterparts
+   can be found in src/msg/msg_legacy.cpp).
+
+S4U:
+ - Introduced new function simgrid::s4u::Host::get_actor_count. This function
+   returns the number of actors running on a specific host.
+
+Plugins:
+ - Allow to run the Link energy plugin from the command line with
+   --cfg=plugin:link_energy
+ - Rename Energy plugin into host_energy
+ - Rename Load plugin into host_load
+
+simix:
+ - Add parameter --cfg=simix/breakpoint to raise a SIGTRAP at given time.
+ - kill simix::onDeadlock() that was somewhat dupplicating s4u::on_deadlock()
+ - Improve performance when handling timeouts of simix synchros.
+
+SMPI:
+ - SMPI is now tested with ~45 proxy apps from various sources, with none or 
+   only minor patching needed : check 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.
+
+XBT:
+ - Config: the C API is now deprecated (will be removed in 3.23), and
+           the C++ API has been slightly improved.
+
+Other:
+ - Fix several build issues on OSX.
+ - Move simgrid_config.h to simgrid/config.h (old header still working)
+
+Fixed bugs:
+ - #143: Setting a breakpoint at a given time
+ - #150: Inconsistent event names in SMPI replay
+ - #258: daemonized actors hang after all non-daemonized actors have completed
+ - #267: Linker error on unit_tmgr
+ - #269: SMPI : tracing of MPI_Wait/all/any broken
+ - SMPI : Fix various crashes with combined use of MPI_PROC_NULL and MPI_IGNORE_STATUS
