+## PHPUnit version notes
+
+- PHPUnit 10–12: [`withConsecutive()` was removed](https://github.com/sebastianbergmann/phpunit/issues/5063), so this library provides a drop-in replacement (see the [PHPUnit 9.6 deprecations note](https://github.com/sebastianbergmann/phpunit/blob/9.6/DEPRECATIONS.md)).
+- PHPUnit 13+: PHPUnit ships a native alternative [`withParameterSetsInOrder()`](https://github.com/sebastianbergmann/phpunit-documentation-english/issues/405), announced in [PHPUnit 13.0](https://phpunit.de/announcements/phpunit-13.html).
+
+If you only target PHPUnit 13 or newer, use the built-in methods. This package stays useful when you need one codebase that runs on both PHPUnit 10–12 and 13+.
