Consider adding official releases

[func0der]

Hey there,

could you add official releases to your repo?

There was an issue over at the sury repo (oerdnj/deb.sury.org#981) which suggested that he might be willing to host the package if there were official releases.

I think this would be a huge relief for all developers working with this extension.

The terms and conditions should be discussed directly with @oerdnj :)
