My distribution project is managed with git, The last tag is 0.1.2.dev1. I use PDM (https://pdm-project.org). The relevant snipped in pyproject.toml is: [build-system] requires = ["pdm-backend"] build-backend = "pdm.backend" [tool.pdm] distribution = true version = {source = "scm", write_to = "ff_testpkg/version.py", write_template = "__version__ = '{}'" } On pdm build: pdm build Building sdist...

This means 0.1.2.dev1+d20250221 should be allowed, right? Continue reading...
