Invalid __version__ attribute in __init__.py file.

[jcbertin]

The __version__ attribute in __init__.py should match the release version i.e. 2.3.0 in 346cea7.

It would be great if this attribute were automatically updated when you publish a new version 😉.

Thank you for taking care of this cool package.
Cheers!

Thanks for letting me know @jcbertin, I've added a test to ensure I don't forget to bump the version in __init__.py.
