-SimGrid (3.24.1) NOT RELEASED YET (v3.25 expected December 22. 2029, 04:19 UTC)
+SimGrid (3.25.1) UNRELEASED (target: March 20 2020 or v3.26 on 3/26/20)
+
+C interface:
+ - Many MSG tests were converted to the new S4U's interface in C, that
+   was extended for that.
+
+Fixed bugs (FG#.. -> framagit bugs; FG!.. -> framagit merge requests):
+ - FG#43: xbt::random needs some care
+ - FG#48: The Impossible Did Happen (yet again)
+ - FG!24: Documentation and fix for xbt/random
+ - GH#139: Allow pthread creation in SMPI

+SimGrid (3.25) February 2. 2020 (aka 02 02 2020)
+
+The Palindrom Day Release.
+
+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.
+  - This is mandatory to use the Java bindings.
+  - OFF by default; The plan is to completely remove MSG by 2020Q4 or 2021Q1.
+- 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.
