The version specifier in the code does not match the actual release version #49
Description
Looking at the __version__ marker in the source, it just hardcodes the initial version 0.1.0, while the actual latest release version is 0.9.1 at the time of writing.
The release process needs to be updated, so that the version specifier in the code is properly bumped, and that release metadata is generated from that (in other words, there needs to be a single source of truth).
