3.0.0
This is the first release in the 3.0.x series.
This release adds support for PHP 7.3 and 7.4, and drops support for PHP 5. It's still possible to parse PHP 5 code, but not to run Class Preloader on PHP 5. This is done by upgrading us to Class Preloader 4.x.
Note also that we have dropped support for symfony/console v2, but added support for v5, so we support versions 3, 4, and 5.
