CICE-Consortium/CICE: CICE Version 6.1.0

CICE version 6.1.0 is released with Icepack version 1.2.0. This release includes a major new physics parameterization in Icepack, the joint thickness and floe size distribution (FSD) of L. Roach and colleagues, and a new directory structure for drivers used in host models, especially NUOPC caps.

We continue to work toward an interface for Icepack that is flexible, extensible and easy to maintain, so that future Icepack upgrades minimize the amount of changes required in host models. Toward that goal, this release includes changes to the interface that are not backwards compatible, which are detailed in the Icepack v1.2 release notes.

Major changes:

• Add the joint thickness and floe size distribution (FSD) #382
• Rearrange the driver directory to accommodate NUOPC caps #376 #377 #383

Enhancements:

• Update Icepack version #379, #387
• Update Icepack interface calls to use keywords #378
  and to be consistent with recent refactoring of the interface (see Icepack #285, Icepack #289) #379, #385
• Improve automation of test reporting and Zenodo links #370
• Improve method for launching serial runs #369

Bug fixes:

• Use dyrect in box test #361
• Correct calculation of ANGLET #377 (affects coupled fields)
