The links at RubyForge to download the version 0.8.0 don't seem to work, at least for me.
Can you check ?

They are working for me. Could you try now? Sometimes Rubyforge takes a little bit to sync the files to it's mirrors.

Yes it worked a few hours after.
I was too impatient to disccover the new version.
I could install this version and we are happy with it.
