+- Breaking Minor Change - On PHP 7.4 MySQL version to 5.5.62 to align with WordPress minimum requirements. The version of MySQL can be overridden using a version of PHP that is not 7.4, by setting the `SLIC_DB_IMAGE` environment variable explicitly or by setting the `SLIC_DB_NO_MIN` environment variable to a non falsy value.
