# UPGRADE GUIDE FROM 2.x to 3.0 This is guide for upgrade from version 2.x to 3.0 for using the CLI tool. *Before following this guide, install [v2.19](https://github.com/PHP-CS-Fixer/PHP-CS-Fixer/releases/tag/v2.19.0) and run in verbose mode (`php-cs-fixer fix -v`) or in future mode (`PHP_CS_FIXER_FUTURE_MODE=1 php-cs-fixer fix`) to identify deprecations and fix them first.* ## Rename of files | 2.x | 3.0 | Description | |------------------|--------------------------|----------------------------------------| | `.php_cs` |

removed - `HeaderCommentFixer` deprecated properties have been removed - `MethodArgumentSpaceFixer` deprecated methods have been removed - `NoMixedEchoPrintFixer` the property `$defaultConfig` has been removed - class `Tokens`, the following methods has been removed: - `current()` - `key()` - `next()` - `rewind()` - `valid()` - namespace `PhpCsFixer\Test\` and each class in it has been removed, as it served pure development purpose and should not be part of production code - reach out to community if you are willing to help building dev package ### Interface changes -
