  - Rework the internals, for simpler and modern code. This shall unlock many future improvements.
  - You can now define plugins onto SafetyChecker (a simple DFS explorer), using the declared signals.
    See CommunicationDeterminism for an example.
+ - Support mutex, semaphore and barrier in DPOR reduction
  - Seems to work on Arm64 architectures too.
+ - Display a nice error message when ptrace is not usable.
+ - New test suite, imported from the MPI Bugs Initiative (MBI). Not all MBI generators are integrated yet.
+ - Remove the ISP test suite: it's not free software, and it's superseeded by MBI.
 
 SMPI:
  - fix for FG#100 by ensuring small asynchronous messages never overtake larger
@@ -15,13 +19,35 @@ SMPI:
    not just at the end, reducing memory cost and performance hit.
  - Update OpenMPI collectives selection logic to match current one (4.1.2)
 
+S4U:
+ - New signal: Engine::on_simulation_start_cb()
+ - Reimplementation of barriers natively. 
+   Previously, they were implemented on top of s4u::Mutex and s4u::ConditionVariable. 
+   The new version should be faster (and can be used in the model-checker).
+
+MSG:
+ - MSG_barrier_destroy now expects a non-const msg_barrier parameter.
+
+New plugin: the Chaos Monkey (killing actors at any time)
+ - Along with the new simgrid-monkey script, it tests whether your simulation 
+   resists resource failures at any possible timestamp in your simulation. 
+ - It is mostly intended to test the simgrid core in extreme conditions, 
+   but users may find it interesting too.
+
 XBT:
  - Drop xbt_dynar_shrink().
 
+Python:
+ - Added the following bindings: Comm.wait_for() and Comm.wait_any_for()
+   Example: examples/python/comm-waitfor/
+
 Fixed bugs (FG#.. -> FramaGit bugs; FG!.. -> FG merge requests)
  (FG: issues on Framagit; GH: issues on GitHub)
+ - FG#57: Mc SimGrid should test whether ptrace is usable
+ - FG#87: Smpi scripts fail with spaces in paths
  - FG#100: [SMPI] Order of the message matching is not guaranteed
  - FG#101: LGPL 2.1 is deprecated license
+ - GH#151: Missing mutexes for DPOR.
