Has anybody used this I noticed they have a new version today.

I have tested it before, nice little distro. It's more oriented to KDE and is now using rpm for package management but initially used to use Slackware tgz's.

Oh where do I begin, try it out and you are gonna be amazed. Yoper has come a long way and is only getting better. Speed is awsome, apt takes care of dependancy h#ll. And synaptic (or kpackage) makes installing packages a breeze. Granted Yoper still has a way to go as compared to some of the other "commercial linux distros". I'm not saying it's not good, just we need more packages added in, more testing done, etc. The rpm packages are optimized for speed on the Yoper distro so that's why the apt repos aren't that big for it yet. You can still compile software and should be able to use most other rpm packages but if you can find it allready in YOPER repos, you'll gain benifits from this.
Check it out, you'll be glad you did.
