Does Obtinaium have a stable release or is it just beta?
You can choose. It can grab directly from github.
Every release of Obtainium appears to be a beta test. I do not see any option to choose a stable release of Obtainium.
Ooooh sorry you ment of obtainum. My bad. Yeah as far as I know there is no stable version.
That being said, I've been using it now for several months and have had very little issues with it.
