-SimGrid (3.31.1) NOT RELEASED YET (v3.32 expected June 21. 2022, 09:13 UTC)
+SimGrid (3.32.1) not released yet (target december 22)
 
 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().
+ - Activity::set_remaining() is not public anymore. Use for example
+   Comm::set_payload_size() to change the size of the simulated data.
+
+MPI:
+ - New option smpi/barrier-collectives to add a barrier in all
+   collectives to detect dangerous code that /may/ work on some implems.
+
+Models:
+ - WiFi: the total capacity of a link depends on the amout of flows on that link.
+   - Use the nonlinear callback feature of LMM to reflect this.
+   - Calibration values can be changed to match different MCS configurations
+   - See the example teshsuite/models/wifi_usage_decay/wifi_usage_decay.cpp
+   - See also "A Flow-Level Wi-Fi Model for Large Scale Network Simulation"
+     https://hal.archives-ouvertes.fr/hal-03777726
+
+Fixed bugs (FG#.. -> FramaGit bugs; FG!.. -> FG merge requests)
+ (FG: issues on Framagit; GH: issues on GitHub)
+ - FG!118: Wi-Fi callback mechanism
+ - FG!119: SMPI: add option to inject a barrier before every collective call, to allow...

+SimGrid (3.32) October 3. 2022.
+
+The Wiedervereinigung release. Germany was reunited 32 years ago.
+
+General:
+ - SimGrid now requires a compiler with C++17 support to compile the lib.
+   Our public headers still allow the user code to be compiled in C++14.
+ - Support graphviz v3 and ns-3 v3.36 (older versions are still supported).
+ - Tested with clang (v11, v13, v14 and v16), gcc (v7 to v13) and IntelCC v2022.2
+
+S4U:
+ - API evolutions:
+   - kill signal Comm::on_completion that was not working anyway.
+   - Expose signals Activity::on_suspend and Activity::on_resume
+   - New macro xbt_enforce(): similar to xbt_assert(), but throws an AssertionError
+     instead of calling abort().
+   - New: s4u::Exec::get_thread_count()
+ - Various cleanups around virtual machines:
+   - host_by_name() and friends now only return hosts. VMs are now excluded.
+   - It is now impossible to search a VM by name globally.
+     You can only search VM by name on a given PM, so either you know
+     the PM on which your VM runs and you can search by name, or you need
+     to manually iterate over all PMs to search this VM.
+   - The s4u::VirtualMachine constructor is now deprecated.
+     Please use s4u::Host::create_vm() instead.
+   - Rename s4u::VirtualMachine::on_creation() to on_vm_creation() to
+     avoid confusion with s4u:Host::on_creation() that is inherited.
+     Also s4u::VirtualMachine::on_destruction -> on_vm_destruction().
+ - Bug fixes:
+   - One-sided communications (Comm::sendto) can now be detached,
+     and should now be more resilient to network and host faults.
 
 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/]
-    - Mailbox: Mailbox.ready [example: examples/python/comm-ready/]
-  - 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.

+ - Added an AssertionError exception that may be thrown in case of error.
+   For instance, creating two hosts with the same name will now throw this exception
+   instead of killing the interpreter.
+
+SMPI:
+ - Implement MPI_File_get_type_extent(), MPI_File_s/get_atomicity() and
+   MPI_File_get_byte_offset()
+ - Intercept getpid() calls to return the simulated ones.
+ - Fix various bugs in MPI IO.
 
 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.
-
-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).
+ - More robust sanity checks for platforms, to reject forbidden topologies with
+   a proper error message.
+ - New platform example: supernode.cpp and supernode.py.
+   The Python version generates a nice graphical representation of the platform.
+ - Bug fixes around fat-tree topologies.
+ - Allow to dump the platform topology as a CSV file representing the graph edges
+   with platform_graph_export_csv() (similar to the DOT export).
+ - Fix graphicator for "cluster" topologies (e.g. fat-tree, dragonfly).
+
+Models:
+ - Fix a bug when using ptasks with multicores (FG!111).
+
+Model-Checker:
+ - First bits of sthread, that intercepts pthread operations at runtime.
+   The intend is to use it together with simgrid-mc, but it is TBD.
+ - Sync MBI generators with upstream changes.
+ - Various cosmetics, small bug fixes and inner refactorings
 
 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#110: Wait_any does not trigger new model solve when host events occur
+ - FG#111: Wrong execution time in rare cases when using multicore
+ - FG!98: Re-enable the tests for legacy stochastic profiles
+ - FG!109: Trigger new engine solve upon host events such as host on/off
+ - FG!116: SMPI/replay: Fix issue with recv of size =0
