5      ==============================      ==============================
6    
7    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
8     (allow to differentiate between forcing components using new integer flags:
9      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
10     and add new flag to put Dissipation tendency out of Adams-Bashforth.
11    o ecco
12      - enable trend removal from SSH anomaly obs.
13    o adjoint
14      - a fix for PmEpR when #undef EXACT_CONSERV
15      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
16      - try to fix "hidden" recomp. in forward_step for NLFS
17        (NLFS seems broken sometimes after I checked it in)
18    o seaice:
19     - add c-grid version of the dynamic solver:
20       + three new routines that are the c-grid substitute lsr, dynsolver
21         and ostres
22       + put a few fields that were local to dynsolver into global common
23         blocks, so that I can move the computation of stresses etc into
24         seaice_lsr (saves coding but may break the adjoint).
25     - replace more hardwired parameters by runtime parameters
26     - add ice masks that mask the rhs of the implicit solvers where there
27       is no ice (commented out in seaice_dynsolver, because i am not sure
28       if this works properly), eventually this should replace the clipping
29       of ice velocities in seaice_dynsolver to +/-40cm/s.
30    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
31      include it only where its needed
32    o move balancing of fluxes before the call of external_forcing_surf
33    o seaice:
34      - correct units of turning angles (now they are really in degrees)
35      - move computation of GWATX/Y out of main routine into dynsolver
36      - initialize GWATX/Y in seaice_init
37    o Apply mask on Fresh-Water flux (needed for SSH forcing).
38      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
39    o seaice: add runtime flags for turning angles (default to zero)
40    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
41      and trend from exf forcing and ctrl control adjustments
42    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
43      (since checkpoint57x_post)
44    o change the default rotation period to 86164.s = the Earth rotation
45    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
46      and based on a reference stratification. Tested within hs94.cs-32x32x5.
47    o seaice advection: add code for choosing between the default (2nd order
48      central differences) and multiDim advection schemes provided by
49      pkg/generic_advdiff
50  o seaice:  o seaice:
51    - removed all references to SEAICE_GRID.h fields from    - removed all references to SEAICE_GRID.h fields from
52      dynsolver, advect, diffus, lsr, without changing the results of lab_sea      dynsolver, advect, diffus, lsr, without changing the results of lab_sea

57      (still commented out)      (turn on with SEAICEuseFluxForm)
