> The $version parameter of curl_version() is deprecated. If any value not
> equal to the default CURLVERSION_NOW is passed, a warning is raised and the
> parameter is ignored.

Notes:
* While the changelog and the PHP native deprecation message call the parameter `$version`, the documentation calls it `$age`, so that's the parameter name used for the error message.
* Using the `CURL_VERSION_NOW` constant for the value is still fine, so the sniff takes that into account.
