Not really, we just put it in maintenance mode -- no more features just
bugfixes.

We can deploy it to aur-dev.archlinux.org and have users test it before
we deploy it to the real website.

The reason I don't want to deploy it to the real installation right
away is mainly because we are changing the database structure. The plan
is to move to SQLAlchemy (you already have a patch for this) and then
start implementing the Flask app. If we mess something up in the
database backend and it does not become apparent at me moment, we are
screwing up the production database.
