Pattern: Low PHPCS version
Issue: -
Add a notification for users of low PHPCS versions. Originally PHPCompatibility supported PHPCS 1.5.x, 2.x and since PHPCompatibility 8.0.0, 3.x. Support for PHPCS < 2.3.0 has been dropped in PHPCompatibility 9.0.0. The standard will - up to a point - still work for users of lower PHPCS versions, but will give less accurate results and may throw notices and warnings (or even fatal out). This sniff adds an explicit error/warning for users of the standard using a PHPCS version below the recommended version.
