YAXT

The 0.9.2 release includes the following new features:

• The neighbor alltoall exchanger is now expected to fully work on MPI's where MPI 3.x features are available, test it by setting environment variable XT_CONFIG_DEFAULT_EXCHANGE_METHOD to neigh_alltoall

It also contains new work-arounds for the following compilers:

• gcc/gfortran 10 and 11, especially when using -flto
• Intel Fortran 19.1 Update 2
• PGI/NVHPC compilers 20 and 21

Also a work-around for bugs in mpich 3.4.x releases is included, but the recommended fix is to apply the patches in source:config/checkpatch

Apart from that the release contains multiple measures to save memory and MPI resources.
