 Timberwee is stable, is OpenSUSA 11.4, or whatever the last one, with stable packages. That's it. So think of it as the last major release of OpenSUSA, and you add the latest stable packages on top of it. That's it. So if you want to install, run Timberwee, install the latest stable release of OpenSUSA, which today is 11.4, and then chain, add one repo, and you'll suck in the updated packages. And that's it. It's an add-on on top of the last stable one. When 12.1 comes out, your system will upgrade to 12.1, and Timberwee will be on top of 12.1. There won't be any ISO that I can just download easily. It's not that big.
