+Bug Fixes:
+----------
+
+Fixed unitialized bare soil albedo.
+
+	Files Affected:
+
+	full_energy.c
+
+	Description:
+
+	Previously, bare_albedo was unset for the bare soil case (`iveg!=Nveg`).
+	This fix sets the bare_albedo to the global variable value of
+	`BARE_SOIL_ALBEDO`.
+
+
+
+Cleanup of frozen soil option constraints.
+
+	Files Affected:
+
+	calc_surf_energy_bal.c
+	get_global_param.c
+
+	Description:
+
+	Removed hardcoded, behind the scenes checks for the `EXP_TRANS` and
+	`NO_FLUX` global parameter values for case of `QUICK_SOLVE=TRUE` in
+	`calc_surf_energy_bal`.
