I am happy to announce the availability of the new multilib repository. At this time, it contains wine, skype and flashplugin. Furthermore, a multilib compiler is available.
With the launch of the multilib repository all old 'lib32' packages are being removed from community - the core/extra/community repositories will be "pure 64 bit" again.
If you want to use the new multilib packages (and most desktop or laptop users probably do), add the following lines to your pacman.conf:
[multilib] Include = /etc/pacman.d/mirrorlist
