If you're curious what this means... years ago, Firefox took forever to hit 3.6, and the decision was made (mirroring Chrome) that releases would switch from "release when everything is done" to "the trains always run on time", where the release would go out at a predetermined time and anything that was ready would make it.<p>Mozilla also has a habit of simple question-based domains, such as "arewefastyet.com", for tracking progress.
