Where is the source of the released 1.0.5 maintained? #25

This repository is at 1.0.3, last pushed in April 2016. The customisation database ships 1.0.5, validated January 2022, and that package matches rmcgirr83/adduser byte for byte at its "Version 1.0.5" commit — including the v104 migration and the PHP 8 fixes ($s{i} → $s[i]) that are not here.

RMcGirr83 is listed as a past contributor on the contribution page and has closed a pull request of mine there, pointing back to this repository. So the released code is in neither place I can file against.

I have a change ready for the extension. Where does it belong?
