This release stabilizes the source code and makes the foundation for new discretizations, solvers, and example simulators. Significant changes in the MRST 2010a release:

• unified state objects (solution objects for reservoir and wells have been merged)
• new way of representing fluids
• extensive changes to the grid data structure, which is fundamental in MRST
• utility routines for creating triangular, voronoi, and extruded grids
• support for interior boundaries for general grids
• improved visualization tools (iso-contours, export to vector graphics now working)
