Great to see a target for a release! Personally I think the momentum of the project would benefit more from having a release to refer to, than any (other) new feature or improvement. I understand range queries are a priority for you Jonathan. I still wonder if it would not be better to limit 0.3 to only bug fixes (priority major or above)?
