I have the latest from archlinux.fr repo which is indeed 0.9.5.1-1. When i try -Syua it says "-a" is an unrecognized option. Also, the man pages show no such option (all i see is --aur). I'm not home right now so i'll give more details a bit later...

I thought "-Syua" would be cool, but it doesn't exist (or at least not anymore). That'd be the cleanest way to do it!

Thanks.

Packages should be upgraded when attempting to do "yaourt -Syu"
