-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)
+
+General:
+ - Remove the MSG API: its EOL was scheduled for 2020.
+ - Remove the Java bindings: they were limited to the MSG interface.
+ - On Windows, you now need to install WSL2 as the native builds are now disabled.
+   It was not really working anyway.
+
+S4U:
+ - Activity::set_remaining() is not public anymore. Use for example
+   Comm::set_payload_size() to change the size of the simulated data.
+ - New function: Engine::flatify_platform(), to get a fully detailed vision of the
+   configured platform.
+
+Kernel:
+ - optimize an internal datastructure, leading to a potentially big
+   performance gain (in particular with many detached comms)
+
+MPI:
+ - New option smpi/barrier-collectives to add a barrier to some collectives
+   to detect dangerous code that /may/ work on some MPI implems.
+
+Models:
+ - Write the section of the manual about models, at least.
+ - 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
+ - Merge parameters network/bandwidth-factor and smpi/bw-factor that serve the same purpose.
+   - Same for the latency
+   - Rewrite the corresponding documentation.
+ - Allow to disable the TCP windowing modeling by setting network/TCP-gamma to 0.
+
+sthread:
+ - Implement pthread_join in MC mode.
+
+Documentation:
+ - New section in the user guide on the provided performance models.
+ - New section presenting some technical good practices for (potential) contributors.
+ - Add a section on errors and exceptions to the API documentation.
+ - Move the s4u examples to a section on their own to ease navigation.
+
+Fixed bugs (FG#.. -> FramaGit bugs; FG!.. -> FG merge requests)
+ (FG: issues on Framagit; GH: issues on GitHub)
+ - FG#18: Java bindings should be redone or removed
+ - FG!118: Wi-Fi callback mechanism
+ - FG!119: SMPI: add option to inject a barrier before every collective call, to allow...
