The configuration file you are using, if any:

<?php

$finder = PhpCsFixer\Finder::create()
    ->in([__DIR__.'/src'])
    ->exclude(['Tests'])
;

return PhpCsFixer\Config::create()
    ->setRiskyAllowed(true)
    ->setRules([
        '@Symfony' => true,
        'no_unused_imports' => false,
        'array_syntax' => [
            'syntax' => 'short',
        ],

        ],

    ])
    ->setFinder($finder)
;

If applicable, please provide minimum samples of PHP code (as plain text, not screenshots):

• before running PHP CS Fixer (no changes):

namespace Yprox\Model\Site\Parent;

• with unexpected changes applied when running PHP CS Fixer:

namespace Yprox\Model\Site\parent;

• with the changes you expected instead:

no changes

[keradus]

using semi-reserved words as namespace is not best idea imho :(

[kmvan]

Why not rename the Parent namespace?

No matter if it's a good idea or bad it is a bug -> #3937

Can be closed now, is fixed as of 2.12.3
