Likely the last release of 2017, Laravel 5.5.28 shipped on December 28th.
notifyNow() method was added to the
AnonymousNotifyable class, which allows you to do:
Notification::route('mail', 'firstname.lastname@example.org')->notifyNow(new UserNotification($message));
This release also adds an
EventFake::assertDispatchedTimes() method to assert the number of times an event is dispatched.
Also worth mentioning, a fix was merged for properly handling inline message for size rules.
