 ### Added
 
-- Added subroutine `MAPL_SunGetLocalSolarHourAngle()` in `base/MAPL_sun_uc.F90`. This provides a
-  convenient local solar hour angle diagnostic which will be used to detect local
-  solar noon via the EXAMPLE OF USE in the subroutine header. See DESCRIPTION in code for more
-  details. Provides the TRUE local solar hour angle (i.e., with equation of time included), but
-  can also provide the MEAN value (without EOT) via FORCE_MLSHA=.TRUE. optional argument.
-- Changed call to MAPL_SunOrbitCreate() inside MAPL_Generic.F90 to new MAPL_SunOrbitCreateFromConfig,
-  the latter which get the orbital parameters from the MAPL state's Config. In this way no default
-  orbital parameter values need appear in MAPL_Generic.F90. Rather, these default values are encap-
-  sulated where they belong in Sun_Mod in base/MAPL_sun_uc.F90 and are now explicitly named and
-  commented at the head of the module. This is a structural zero-diff change.
