 SimGrid (3.24.1) NOT RELEASED YET (v3.25 expected December 22. 2029, 04:19 UTC)
 
+Important user-visible changes:
+- Improve the Python usability (stability and documentation).
+  - A nasty synchronization bug was ironed out, see also below.
+  - Python's doc was organized as a separate tree, now integrated with C++.
+  - C bindings of S4U were not part of the doc.
+  - The C++ doc was also improved as methods are now split by theme.
+- Further deprecate MSG: you now have to pass -Denable-MSG=ON to cmake.
+  - The plan is to completely remove MSG by the end of 2020.
+- SimDAG++: Automatic dependencies on S4U activities (experimental)
+  - Some features are already implemented but not all of them
+  - Cannot block an activity until it's scheduled on a resource
+  - No heterogeneous wait_any() that would mix Exec/Comm/Io activities.
+  - See examples/s4u/{io,exec,comm}-dependent for what's already there.
+
+
+
 General:
 - Upgrade documented Java dependency to Java 8 (earlier versions don't work).
+- Drop support for Viva/Triva (old visualization tools), hence removed
+  TRACE_get_node_types() and TRACE_get_edge_types() functions.
+
+Python:
+- Require pybind11 version 2.4.
+- Greatly improve locking during context switches with Python.
+  - Declaring Python callbacks to this_actor::on_exit is now working.
+  - No more tests are failing currently, even on win32.
