[License-review] Submission: PSF-2.0

[Max Mehl]

Dear all,

After OSI has approved Python-2.0.1 and one of its components (CNRI-Python-GPL-Compatible), I would like to use the opportunity to ask the team and board to review and approve the "Python Software Foundation License 2.0" (SPDX: PSF-2.0). The license text, copied from https://docs.python.org/3/license.html and matching SPDX’ version, is attached.

This also follows McCoy’s statement that such reviews are only executed upon explicit submission, see https://lists.opensource.org/pipermail/license-review_lists.opensource.org/2026-August/006218.html

PSF-2.0 is the license of the PSF, and part of the combined license of CPython releases (Python-2.0 and Python-2.0.1). But it’s also used verbatim and derived standalone by various projects, mostly in the Python ecosystem. Because of this, I consider it helpful to approve the license separately. Examples:

  *
https://github.com/jython/jython
  *
https://github.com/marcelotduarte/cx_Freeze
  *
https://github.com/chianjin/PDFeXpress

Given that Python-2.0 and Python-2.0.1 both comply with the OSD, I’d consider it clear that PSF-2.0 can also be safely considered an Open Source license.

The license steward is Python Software Foundation. As with my earlier submission, I refer to a discussion with Deb Nicholson in March 2026 in which she made transparent that PSF currently lacks the resources to go through this process and would be happy if I would do this.

I hope to have provided all required information and hope for a swift and positive review and approval. Thanks!

Best,
Max
