As a suggestion,
Can you please leave the 4.0.x branch files in our members area as a Legacy product? There are still a number of people who not only use the older version, but if their site was defaced etc, and they needed to re-install the same version, they would need the old 4.0.x files.
Other than that, congrats on the announcemnt! We've been waiting for this day for quite some time
