Wrong parameter type used? boolean not Bool

[mspacemedia]

Warning: "boolean" will be interpreted as a class name. Did you mean "bool"? Write "\SilverCommerce\Postage\Forms\boolean" or import the class with "use" to suppress this warning in /home/walledgarden/public_html/vendor/silvercommerce/postage/src/Forms/PostageForm.php on line 98

From line:

98 public function setBackOnNoOptions(boolean $back_on_no_options)

/dev/build stil process but kicks out this warning…

Taken me a little while to get to this one... But this should be fixed in 508cbcd
