As per the Fedora 16 schedule [1], Fedora 16 Final Release Candidate 4
(RC4) is now available for testing. Please see the following pages for
download links (including delta ISOs) and testing instructions.
Serverbeach1 is still available as a mirror (but with approximately a 1
hour lag behind dl), so if you are getting a slow download, try
replacing "dl" with "serverbeach1" in the download URL.

what has changed between rc3 and rc4? is there a place where we can read the changelog?
