[Cooker] 2007.1 release notes

[Vincent Panel]

Although the errata page seems quite complete, the release notes are
almost empty.

The goal is to give little background information about what have
changed in 2007.1 compared to 2007.0. For instance, I think this is
the good place to discuss about the new suspend/hibernate framework
and resolvconf. I've seen the thread about the way to change the
"star" icon for KDE : maybe it should be added here too.

If you see anything else which should be discussed, feel free to add
your findings in this page it could help other users.
