# UPGRADE FROM 2.0 to 3.0 The main change, apart from requiring PHP >= 7.4, is that `Utils` and `AbstractSoapClientBase` method `getFormatedXml` has been renamed to `getFormattedXml` (typo fix). **Previously**: ```php WsdlToPhp\PackageBase\Utils::getFormatedXml($xmlString); WsdlToPhp\PackageBase\AbstractSoapClientBase::getFormatedXml($xmlString); ``` **Now**: ```php WsdlToPhp\PackageBase\Utils::getFormattedXml($xmlString); WsdlToPhp\PackageBase\AbstractSoapClientBase::getFormattedXml($xmlString); ```
