Woot, they added a new method to the interface in 8.4?

Great, so we will need to make a breaking change in Chronos for 8.4 compatibility.

The risk of extending PHP classes although this is a very rare change.

Need help with this :)

Yay, only 1 error.

1) Cake\Test\TestCase\I18n\Formatter\IcuFormatterTest::testBadMessageFormat
