Modify build to optionally build Babel interface. Add build option to add "sequence" keyword to all MCT datatypes. Add new perrwith="quiet" option to m_attrVect:index routines. Add new example: climate_sequen1. This shows a sequentially coupled model with init/run/finalize mehods and which uses MCT for coupling. Add Cray compiler directives (thanks to Matthew Cordery). |

New mpi-serial library for using MCT without MPI. Add support for Pathscale compiler. Confirmed support for Lahey compiler. Add new GlobalSegmentMap::init_index function to initialize a GSMap from a list of local points. Add new AttributeVector::Unpermute function. Bug fix (22): AttributeVectorComms::gather now works for masked GSMap Av's Bug fix (24): Merge::MergeInData fix use statement. Also fixed bug numbers (from bugzilla): 17,18,19,23,25 Clarify Router/Rearranger documentation wrt GSMap point order. Remove unused mpeu/mpi0 directory. |

Specify initial value of Av gather New GSMap functions: copy, max local segments, increasing logical New MCTWorld function: initialized logical Router and Rearranger: print Router info, check if GSMaps are increasing SparseMatrixPlus: return Strategy as a character string for printing. Improvements: Another reduction in memory needed in Router init and Rearranger init. lsize no longer required in export routines mpi-serial now supports mpi_pack,mpi_unpack, mpi_allgatherv, mpi_get_processor_name, MPI_Aint, also MPI_PACKED, MPI_MAX_PROCESSOR_NAME, MPI_OP_NULL, MPI_BOTTOM, MPI_User_function.
