Ok. Now that I have emerge the new packages in portage it is time to say my first impressions.
My mousbuttons (number 2 and 3 with evdev) is still swapped.
My keyboard have stopped working as it should. Local keys work, however Alt and Alt Gr does not so I can't switch to framebuffer-console and I can't make (at)...

What happened with that one in the transition from RC0 to RC1?
