2.0.0 -- Graphmos

This is not quite as experimental as it was a few months ago, but I can still see some odd things happening in the corners. Update with caution and don't commit too hard to it. Despite the major version revision only being due to feature flags changes (see MIGRATING.md), you should still take it with caution.
