The docs say that spatial_adapter supports ActiveRecord v2.2 and higher, but the spatial_adapter.gemspec also prohibits 3.1.0 and higher ('activerecord', '>= 2.2.2', '< 3.1.0'). I'll clone and modify the version to see if anything breaks under 3.1. Just wanted to first ask if this might be as simple as updating the gemspec or if there's known issues with the spatial_adapter and AR 3.1.0?
Thanks,
Andrew
