Consider switching to semantic versioning

[noisycomputation]

It looks like the version bump from 1.5 to 1.6 was an API-breaking change. I had been pinned to 1, but things stopped working when I updated to 1.6.

Could you consider moving to semantic versioning?

Is there a reason you don't git tag your version bumps? Having to look at the commit history is not the most efficient way of figuring out what happened when.
