We're urging you to test this release as soon as possible.
This is an "alpha" pre-release covering PR #545 - on top of PR #538 .
Essentially this PR is non-breaking, unless you're using dependency injection to instantiate the MollieApiClient.
You can test it by setting the following in your composer.json file:
"mollie/mollie-api-php": "2.31.1-alpha",
and run composer update.
