@marc-mabe can you have a look at this? :)

[marc-mabe]

Hi @pascalheidmann ,
Why do you remove supported PHP versions only to upgrade PHPunit?

[pascalheidmann]

@marc-mabe these PHP versions are way beyond their EOL, and PHPUnit 9 therefore requires at least PHP 7.3 (also already EOL)

[marc-mabe]

Hi @pascalheidmann,
EOL PHP Versions means it's not supported by PHP anymore but there are distros having much longer (payed) support plans including PHP.
Anyway upgrading the minimum PHP Version requires some kind of benefit which I don't see here.
If you want to improve or simplify the tests which requires the new version I'm open for it.
