PHP 7.4 was branched 10 days ago, and master is now PHP 8.0.0-dev.
This means that using
php: nightly in my builds conflicts with phpunit which expects PHP 7:
phpunit/phpunit 7.5.4 requires php ^7.1 -> your PHP version (8.0.0-dev) does not satisfy that requirement.
php: 7.4 is not available yet:
rbenv: version `7.4’ not installed
Could you please add the
php: 7.4 version, that would point to the PHP-7.4 branch?
