4.0.0 / 2023-08-04

• Upgraded to Ansible 8.2.0

• Changed from [pipenv][] to [pdm][] and pyproject.toml because of ongoing issues with Dependabot not detecting dependencies in Pipfile.lock as opposed to only in requirements.txt (the inverse of dependabot/dependabot-core#6200). After trying Poetry (predates the latest Python packaging PEPs), rye (experimental), and hatch (no lock file), [pdm][] seems to fit the bill best for the limited needs that we have with this project.

• Experimentally removed the generated requirements.txt file. It isn't used, but it has been valuable in getting update notifications from Dependabot, although the update PRs are less useful. If required, we can add it back with pdm export -f requirements > requirements.txt.
