 SimGrid (3.30.1) NOT RELEASED YET (v3.31 expected March 20. 2022, 15:33 UTC)
 
+SMPI:
+ - fix for FG#100 by ensuring small asynchronous messages never overtake larger
+   ones, conforming to the standard.
+ - replay: fix waitall behaviour to avoid forgetting requests and leaking
+   their handles.
+ - tracing: ensure that we dump the TI traces continuously during execution and
+   not just at the end, reducing memory cost and performance hit.
+
 XBT:
  - Drop xbt_dynar_shrink().
