Today it is the scheduled date of the final Feisty Fawn version of Ubuntu, 7.04 which has been under development for the past six months.
Ubuntu's website is already under heavy traffic, and, for those who will want to download the distribution right after the release, bit torrent should be the best choice. There will be hundreds of people sharing, so, speed won't be a problem.
I hope that Ubuntu 7.04 is at least as successful as the previous version, and I'm happy to congratulate everyone involved in this awesome community. Thank you for your work. We're all making the most usable Linux distribution out there! Let's keep raising the bar!
Update
It is out, see the release notes, or, go get it.
