as discussed we build a new set of ISOs/USB-Images with the state of a ReleaseCandidate. http://dev.archlinux.org/~aaron/archiso/
Please test them (esp. for the open bug-reports above). Test phase should go over this weekend, so that we probably could make the final release (sic!) during next week.
Known issues: low -> grub entry "Release Notes" present a empty To-Do list
PS; Upload of most ISO and IMG files are already finished, the missing core-* files will be there in 1,2 hours. (@Aaron: could you provide an updated sha1sums file when finished?)
