This release addresses minor bugs in the internal derived data type packing/unpacking where

• MPI_FLOAT_INT might lead to a SIGBUS on some architectures.
• Reference tests for 0-size datatypes incorrectly use a buffer of size 0, but the MPI spec requires a buffer of the size provided by MPI_Pack_size.

If you already have a build of 0.10.1 that passes all tests, there is no need to upgrade. But it is strongly recommended for RISC platforms (NEC SX, ARM64, PPC64 and others).
