For those people who enjoys messing with things until they break (I’m one), this from ubuntu-devel-announce:
The Gutsy Gibbon archives are now accessible, and will be openend soonish for normal upload and syncs from Debian.
The current gutsy archive already has some basic packages updated, including our toolchain (binutils, GCC, glibc). …
Just a week after the big Feisty release, and the Gutsy archives are opened. That’s dedication.
So anyway, if you’re feeling daring, you could probably swap repositories now, and start playing with the new toys. It’s always fun to start early with the new version, and see how long you can use it before it breaks altogether.
I have a weird idea of fun sometimes.
