PHP 7.2 build on Travis is already enabled and running, the very last issue we need to solve is jeremykendall/php-domain-parser#205. After the stable package is released (or we find another way around it), a patch release will be tagged.

If you do need PHP 7.2 support right now, just require this package in 4.0.3-alpha version and everything should work just fine 🎉
