  • allows climate forcing using spatially-varying “anomalies” (near-surface air temperature and precipitation)
  • includes better metadata handling
  • can be stopped and restarted without affecting results of a run
  • has more software tests (including regression tests)
  • has an automatic vertical grid extension mechanism
  • performs area and volume calculations using WGS84 datum to correct projection error
  • makes the computation of the age of the ice optional, for efficiency
  • has easier-to-extend source code
  • comes with three worked examples: Antarctica, Greenland, Storglaciaren
