+General:
+ - LTO is now enabled for Intel/clang compilers.
+ - LTO behavior on GCC can be parameterized using LTO_EXTRA_FLAG in cmake.
+ Setting it to "auto" will use all available cores, while setting it to n will
+ use n cores to speedup link step (usage: cmake -DLTO_EXTRA_FLAG=4).
+ - Remove obsolete option --cfg=contexts/parallel-threshold.
+ - Further improve the documentation.
+
+S4U:
+ - the on_exit() of each actor is also executed when the simulation deadlocks.
+ - New functions: s4u::Activity:: suspend(), resume() and is_suspended()
+ An example is provided for s4u::Comm but it should work with Exec and Io.
+
+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.
+ - Many MSG tests were converted to the new S4U's interface in C, that
+ was extended for that.
