Thank you! By the way what's the difference in semver for this version range with direct 0.7 ?

If I'm understanding your question correctly, I think you're asking why I did this:

- geo-types = "0.6.0"
+ geo-types = ">=0.6.0, <0.8.0"

Instead of this:

- geo-types = "0.6.0"
+ geo-types = "0.7.0"

Is that your question?

I did it that way because, though there are semver incompatible changes in geo-types, none of those changes matter for the API's that this geohash crate uses.

So users of geohash could use either geo-types 0.6 or 0.7.
