 3.0.2 (unreleased)
 ==================
 
+- Packaging: Add a minimal ``pyproject.toml`` to sdists.
 - Fix a test case on Arm32. Note that this is not a supported platform
   (there is no CI for it) and support is best effort; there may be
   other issues lurking. See `issue 385 <https://github.com/python-greenlet/greenlet/issues/385>`_
