Python 3.14 (the π version) was released today.

.github/workflows/build-tarball.yml

        uses: actions/setup-python@a26af69be951a213d495a4c3e4e4022e16d87065  # v5.6.0
        with:
          python-version: ${{ env.PYTHON_VERSION }}
+          allow-prereleases: true


I guess we dont need this anymore?

I usually just leave them in place so we can test Python 3.15, etc.
