 The exit codes used by PHP_CodeSniffer have changed. This change was made primarily to allow for `phpcbf` to exit with a `0` exit code if all fixable issues were fixed and there are no non-auto-fixable issues remaining.
 
 The pre-existing [`ignore_warnings_on_exit`](https://github.com/PHPCSStandards/PHP_CodeSniffer/wiki/Configuration-Options#ignoring-warnings-when-generating-the-exit-code) and [`ignore_errors_on_exit`](https://github.com/PHPCSStandards/PHP_CodeSniffer/wiki/Configuration-Options#ignoring-errors-when-generating-the-exit-code) config flags will still be respected.
