Icepack version 1.2.4 is being released with CICE6.1.4. This is a minor release update from the Icepack1.2.3 release in August, 2020. This release fixes a couple of minor bugs in the floeshape setting and in the convergence criteria in the atmo_boundary_layer method. In addition, some namelist variables were added and moved between namelist groups. Major changes: Bug fixes: Remove duplicate definition of floeshape and set it to 0.66. Prior versions had it set to 0.666 in fsd and 0.66 outside fsd. This changes answers but only affects the results of the fsd cases. #342 Fix bug in atmo_boundary_layer in the iteration of Z/L, ustar, tstar, and qstar. This may change results slightly and does so in some of the test cases. This fixes the convergence check. #341 Enhancements: Move sw_redist, sw_frac, sw_dtemp from the thermo namelist to the shortwave namelist in the icepack driver. Prior namelist files may not be backwards compatible. #343 Add hfrazilmin and floediam variables to icepack_parameter settings and to the icepack driver. #342 Documentation: Fix ice strength documentation #336 Fix journal reference #339
