+SMPI:
+ - Update proxy apps coverage of new ECP apps: 60+ apps now tested nightly on
+ https://framagit.org/simgrid/SMPI-proxy-apps
+ - MPI/IO: supports names starting with "./"
+ - Fortran: many MPI/IO bindings, support for MPI_UB/LB, C MPI_INT/FLOAT/DOUBLE
+ datatypes.
+ - smpicc/cxx/ff/f90 now will actually perform definition checks at link time. When
+ building shared libraries, this may cause issues, so environment variable
+ SMPI_NO_UNDEFINED_CHECK can be added to disable this.
+
+C binding and interface:
+ - The return type of the sg_actor_on_exit() callbacks is now 'void'
+ (int value was previously ignored)
+ - Many C functions were renamed to follow a common naming style
+ (sg_object_get_something and sg_object_set_something). As usual, the deprecated
+ names are kept until version 3.30.
