MPC 4.1.0 is out !
This release features important changes inside the internals of MPC to feature a more dynamic process model as required by evolutions in the standard. Communicator and group support was done from scratch, and collectives were rewritten to improve performance. In this release, MPC is also moving to GCC 10.2.0 with privatization, note that *autopriv* was renamed to *mpc-compiler-additions*. Eventually, we rely on Hwloc 2+ starting from this release.
