After we delayed the original Fedora 12 Beta release date by a week - it was originally planned to come out today - we confirmed the schedule yesterday, so now we're on the final sprint to have it released next week. How can you help? Good question!
As Liam Li explains, you can grab the Beta RC2 build and help us fill out the installation test matrix. It's a big table showing the various most important variations on the theme of installing Fedora. The easiest way to use it is just to do an install onto whatever spare system or partition you have, then figure out which entry in the table your installation corresponds to, and post your result there. The more dedicated who have entire machines they can use as testbeds, and in some cases multiple hard disks and so on, can go through all the various areas of the matrix and try to fill out as many as they can. And, of course, if you run into bugs - file them!
You can also continue to test the nightly live CD builds and make sure they work as they should on your hardware. Hopefully, this time next week we'll have a rocking Beta release available for everyone to bash on. I'm really excited for Fedora 12, it's going to be a good one.
