David,
Atlas is an an open source project. We provide our work on it for free, in the hope of inspiring a wider community to work together. If you think something needs to be fixed quicker, go ahead and do so.
For reference, we don't regard the film year as a "massive gap", we're not responsible for the data, and I see zero constructive comments from you about the new Atlas 4 documentation when we asked for feedback.
In fact, you've been a member of this group for less than three months, and made no contributions beyond asking questions for your own benefit. If you don't like the project, or need everything on a plate, feel free to go somewhere else. Meanwhile, messages like this force us to consider revising our approach to openness.
Chris
