# 3. Version 1.2 of MPI

Up: Contents Next: Version Number Previous: Examples

This section contains clarifications and minor corrections to Version 1.1 of the MPI Standard. The only new function in MPI-1.2 is one for identifying which version of the MPI Standard the implementation being used conforms to. There are small differences between MPI-1 and MPI-1.1. There are very few differences (only those discussed in this chapter) between MPI-1.1 and MPI-1.2, but large differences (the rest of this document) between MPI-1.2 and MPI-2.
