Python users: The names of the Anaconda Python modules have been changed to anaconda/5.2.0-py2.7 and anaconda/5.2.0-py3.6

MPI users: You must rebuild your code from source if you are using a version other than IntelMPI. OpenMPI has been dropped for Intel compilers and replaced by MVAPICH2. We highly recommend IntelMPI for Intel users. OpenMPI for gcc has been updated.
