src/Rules/Currency.php:82

• The currencyCodes() method was updated in version 1.1.0, so the @since tag should be updated from 1.0.0 to 1.1.0 to reflect the latest changes.

* @since 1.0.0

• The leading "git " on the opening PHP tag looks like a typo and will cause a syntax error. Please remove it so the file starts with <?php.
