We are currently working on the 2015.10 release of OPM. Some highlights include:

• Significantly improved performance for Flow, the fully implicit black-oil reservoir simulator.
• An experimental black-oil + solvent simulator (Flow-solvent).
• Improvements to the experimental black-oil + polymer simulator (Flow-polymer).
• General improvements (error handling, tests etc.) to many parts of OPM, including the upscaling codes.
