Situation
Node.js 24.x (Active LTS) build fails with Python 3.14.
Python 3.14 is:
py install defaultChange
Backports #59983 (commit 8bc7dfd) to v24.x branch.
The commit message from the backport should be modified, removing the outdated "release candidate 3" text. It is currently:
Python 3.14 was released as GA on 2025-10-07 and is therefore no longer pre-release.
https://www.python.org/downloads/release/python-3140rc3/ states:
Use of the GitHub Actions' actions/setup-python flag setting
allow-prereleases: trueis removed from the backport as suggested by @richardlau in #60874 and explicitly requested by @aduh95. Since the workflow usesPYTHON_VERSION: '3.14'and this is a released Python version, the flag is not necessary.
