+*** Solver restructuring
     The upgrade to the turbulence models means that the simulation type, i.e.
     laminar, RAS or LES can be selected at run time. This has allowed a reduction
     in the number of solvers, simplifying the overall code structure

-* General changes
     + =pd= replaced by static pressure =p=.  All solvers in which buoyancy affects
       might be strong have been converted from using =pd= to =p= with improved
       numerics to give equally good accuracy and stability.  This change is
       prompted by the need to remove the confusion surrounding the meaning and
       purpose of =pd=.

       =uniformDimensionedVectorField= which has the behaviour of a field, is
       registered to an =objectRegistry=, but stores only a single value.  Thus
       =g= and other =UniformDimensionedFields= can be created and looked-up
       elsewhere in the code, /e.g./ in =fvPatchFields=.
 
-** Solver control improvements
-   Use dictionary entries instead of an =Istream= for the solver controls.
+*** Solver control improvements
+    Now uses consistent dictionary entries for the solver controls.
     + This Allows dictionary substitutions and regular expressions in
