Well.. I noticed 2 days ago that my system, after an update, went from 6.0-RC1 to 6.0-STABLE.
Today I got an email with a link to a news site:

You can download 6.0-RELEASE ISOs for i386.. ISOs for AMD64 are here
No mention of it yet on the main website though.. I think they're waiting for all the mirrors to catch up before announcing it..
