5      ==============================      ==============================
6    
7    o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in
8        preconditioner for JFNK (run LSR into the overlaps as far as possible,
9        i.e OLx/y-2, but overwrite the solution in the overlaps)
10      - extend loop range in seaice_calc_viscosity
11      - add new parameters SEAICE_OLx/y (default = OLx/y-2)
12      - add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs
13      - slightly modify loops in tridiagonal solver lsr-preconditioner
14      - by default remove the extra exchange in seaice_preconditioner with a
15        replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE
16      - modify offline_exf_seaice so that old results without RAS are reproduced
17        for output.dyn_jfnk.txt
18      in seaice_fgmres.F (unrelated to RAS)
19      - add a cpp-flag option for a re-ordered mapping (potentially more
20        efficient), but because this changes the results, turn it off by
21        default
22      - replace the save statement by local common blocks
23  o utils/matlab:  o utils/matlab:
24    - fix tile-offset in rdmnc.m when output was produced using EXCH2.    - fix tile-offset in rdmnc.m when output was produced using EXCH2.
25    - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)    - update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab)
