**Full Changelog**: https://github.com/iluvcapra/wavinfo/compare/v1.7.2...v2.0.0

* 13 has been fixed, I've started over with my venv and created separate venvs for the project and the documentation. This has significantly reduced the number of dependencies.
* Have added an action to the publish workflow that will push a status update to my Mastodon account (jamietoot.community) whenever a new release is published.

This release cleans up the documentation on readthedocs.io and adds a bunch of type annotations to make the library more useable.

This is a maintenance update that cleans up some loose ends accumulated over the last year.

- Support for Python 3.5 and 3.6 have been dropped, due to conflicts with dependencies in lxml, a critical dependency of this project.
- The test and packaging workflows for this project have been updated to current best practices on Github.
- Previous test and packaging elements have been removed.

This version has no new functionality or bug fixes.

* Updated `lxml` dependency (CVE-2021-43818)
