5.10 is the minimum version you need, but you can as well specify

use 5.024;

but it would be impolite to other users of your code who run on 5.10 - 5.22, as they can run say, but wouldn't be able to run your code.

My recommendation is to always specify the features you use: it works in all the versions, and you don't have to look up what feature was introduced in what version.

use feature qw{ say };
