+SimGrid (3.31.1) NOT RELEASED YET (v3.32 expected June 21. 2022, 09:13 UTC)
+
+S4U:
+  - Added the xbt_enforce macro. This has the same syntax as xbt_assert. The only difference is that an AssertionError
+    exception is thrown if the condition is not satisfied, instead of calling abort().
+
+Python:
+  - Added the following bindings / examples:
+    - Comm (now 100% covers the C++ interface):
+      - Comm.dst_data_size, Comm.mailbox, Comm.sender, Comm.start_time, Comm.finish_time
+      - Comm.state_str [examples: examples/python/comm-failure/, examples/python/comm-host2host/]
+      - Comm.remaining [examples: examples/python/comm-host2host/, examples/python/comm-suspend/]
+      - Comm.set_payload_size [example: examples/python/comm-host2host/]
+      - Comm.set_rate [example: examples/python/comm-throttling/]
+      - Comm.sendto, Comm.sendto_init, Comm.sendto_async [example: examples/python/comm-host2host/]
+      - Comm.start, Comm.suspend, Comm.resume [example: examples/python/comm-host2host/]
+      - Comm.test_any [example: examples/python/comm-testany/]
+      - Comm.wait_until [example: examples/python/comm-waituntil/]
+    - Engine:
+      - Engine.host_by_name [example: examples/python/comm-host2host/]
+      - Engine.mailbox_by_name_or_create [example: examples/python/comm-pingpong/]
+	  - Engine.set_config
+    - Mailbox: Mailbox.ready [example: examples/python/comm-ready/]
+	- Ptask [example: examples/python/exec-ptask/]:
+	  - this_actor.exec_init
+	  - this_actor.parallel_execute
+	  - Exec.suspend
+	  - Exec.wait_for
+  - Added an AssertionError exception that may be thrown in case of error. For instance, creating tow hosts with the
+    same name will now throw this exception instead of killing the interpreter.
+
+Platform description & visualization:
+  - More robust sanity checks for platforms, to reject unallowed topologies with
+    a proper error message.
+  - One new C++ platform example, supernode.cpp. A Python script (supernode.py)
+    demonstrates how we can generate a nice graphical representation of the
+	platform.
+
+General:
+  - SimGrid now requires a compiler with C++17 support.
+  - Modified the host_by_name functions:
+    - Now, they return only hosts, not VMs, and in a much more efficient way.
+	- If one wants to find a VM by name, he now needs to know the host on
+	which it runs and call vm_by_name (or manually iterate over the list of hosts)
+
+Tools:
+  - Enhancements to the graphicator tool:
+	- Allow to dump the platform topology as a CSV file representing the edges
+	  of the graph (in addition to the DOT format).
+	- Fix graphicator for "cluster" topologies (e.g. fat-tree, dragonfly).
+
+Fixed bugs (FG#.. -> FramaGit bugs; FG!.. -> FG merge requests)
+ (FG: issues on Framagit; GH: issues on GitHub)
+ - FG#105: "Variable penalty should not be negative!" with in-flight messages and bandwidth profiles
+ - FG#109: Application time reported by --cfg=smpi/display-timing:yes is wrong
+ - FG!109: Trigger new engine solve upon host events such as host on/off
+ - FG#110: Wait_any does not trigger new model solve when host events occur
+ - FG#111: Wrong execution time in rare cases when using multicore
+

+S4U:
+ - kill signal Comm::on_completion that was not working anyway.
+ - Expose signals Activity::on_suspend and Activity::on_resume

 Against the agression by a sick system that forces peoples to take arms against each other.
