7    o change default value of tRef (put a uniform, meaningful value for ocean
8      & atmos) and initialize sRef (was missing, as Martin mentioned).
9    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
10      to be proportional to enstrophy dissipation length.  Thus,
11       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
12      This is now consistent with Smagorinsky and with the manual.

15    o OBCS and PTRACERS: add open boundary support for passive tracers
16      - either use homogenous (pseudo) v.Neumann conditions or prescribe
17        OB-values from file; this is not different from the way theta and salinity
18        are treated
19      - however, Orlanski-radiation conditions are not supported, and the model
20        will stop if you use pTracers and Orlanski at the same time.
21      - beefed up the rountine obcs_external_fields_load: now only those open
22        boundary values are overwritten with values from files for which there
23        are really files, otherwise the OB-fields remain untouched. This makes
24        it possible to use different OBs at different ends of the domain (as
25        with EXF)
26    o reduce number of exch calls in shap_filt (s2).
27    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
28      truncation level) 4/5 MLAdjust test results (11&12 digits match).
