Caravela has just been through a rewrite that will make adding future updates easier. In addition, all requests to Caravela are now securely encrypted. You should see a green lock icon in your browser address bar at all times. Functionally, nothing has changed so please let us know if you notice any problems.
You may notice that the typography of the site has changed slightly. We were using Droid but now the site uses the Roboto family. I think you’ll find that Roboto is easier to read. It also includes a Condensed style that is used sparingly in places like form hints and bug lists.
