sorry for the delay, one comment otherwise LGTM

according to standard https://semver.org/ this should be 0.2.0 if we are introducing new funcionality.

[lupemba]

We don't have to do it like that since we are still in version 0.y.z

4. Major version zero (0.y.z) is for initial development. Anything MAY change at any time. The public API SHOULD NOT be considered stable.

The julia package manager uses a slightly different approach to 0.y.z versions where z is incremented for non-breaking changes and y is incremented for breaking changes.
https://pkgdocs.julialang.org/v1/compatibility/#compat-pre-1.0

So if you think 0.2.0 is more pythonic then I will change it but we don't have to do it according to semver.
