Consider following crates.io's own semver flavour

[nox]

I see in the changelog file that this crate attempts to follow semver.

AFAIK, 0.10.0 was released with no breaking changes, only a new feature.

Filing this only in case you are not aware of a couple of facts.

Semantic Versioning itself says that 0.y.z has no rules at all, and that you should not expect any 0.y.z version to be compatible with another 0.y.z version.

On the other hand, the crates ecosystem and cargo both state that it considers the leftmost non-zero number to be the major version. So 0.1.1 is compatible with 0.1.0, but 0.2.0 is not compatible with 0.1.1.

So for example, AFAIK 0.10.0 should have been 0.9.4, if the changelog file is correct.
