• Switch to php-cs-fixer and PER-CS by @KorvinSzanto in https://github.com/thephpleague/fractal/pull/581

Backwards incompatible changes

• Current scope now gets cleared after transformation completes. If you're rely on ->getCurrentScope() after transformation completes, you'll need to update your transformer to capture the value during transformation. See #582
