The nrf_fuel_gauge_process function call has been modified to remove a boolean parameter and replace it with NULL. This appears to be an API change, but without documentation of what the removed parameter represented, this change could affect fuel gauge behavior. Consider adding a comment explaining what functionality was removed or verify that NULL is the correct replacement for the boolean parameter.
