Incompatibility with PHP 7?

Hi there, I’m using the PHP Compatibility Checker plugin and I’m seeing Litespeed cache is possibly incompatible with PHP 7. Is this a false positive or should I really not upgrade?

Here’s the report it’s giving me:

FILE: /wp-content/plugins/litespeed-cache/lib/litespeed/litespeed-crawler.class.php
-------------------------------------------------------------------------------------------------------------
FOUND 1 ERROR AFFECTING 1 LINE
-------------------------------------------------------------------------------------------------------------
 571 | ERROR | The constant "CURL_HTTP_VERSION_2" is not present in PHP version 7.0.6 or earlier
-------------------------------------------------------------------------------------------------------------

Thank you,
Chris
