--- Comment #4 from Davide Cavalca davide@cavalca.name --- Apologies, this slipped through. I'll get it updated shortly.
The versioning is confusing because the VERSION file that setup.py parses, says it's 1.9.0 but the commit you are mentioning suggests, the version is 2.0 now.
afaict the Python library is still versioned as 1.9.0, what's version as 2.0 is the .xd file format (confusingly, the upstream repo commingles the python module and the file format specification).
