- Update to 1.3.0:
* Deliverability checks now check for 'v=spf1 -all' SPF records as a way to reject more bad domains.
* Special use domain names now raise EmailSyntaxError instead of EmailUndeliverableError since they are performed even if check_deliverability is off.
* New module-level attributes are added to override the default values of the keyword arguments and the special-use domains list.
* The keyword arguments of the public methods are now marked as keyword-only.
* pyIsEmail's test cases are added to the tests.
* Recommend that check_deliverability be set to False for validation on login pages.
* Added an undocumented globally_deliverable option.
