"What you have left to do in order to finally Release Luna ?"
There's a post about that here:
[link]"And did you guys at Elementary through about updating the old releases Jupiter to Luna for instance?"
Updating from Jupiter to Luna won't be possible due to the massive technological infrastructure changes between the two. However, updating from Luna to future versions should work perfectly (because of our infrastructure changes).
I also heard about the next release after Luna Will run with Open Source Darwin Kernel Is that true?"
Ha, no, that was an April Fools' joke.
"And Final question. If its true that will mean that you will have to port all of the Elementary Softwares to that kernel?"
Negated by my previous answer. xD
