Every workflow runs actions pinned to Node 20 majors; GitHub removes Node 20 from runners on 2026-09-23

[Kartikey1306]

Every job in this repository logs, on every run:

Node.js 20 is deprecated. The following actions target Node.js 20 but are being forced to run on Node.js 24: actions/checkout@v4, actions/setup-python@v5, …

GitHub's changelog (2025-09-19, editor's note of 2026-08-25): runners use Node 24 by default since 2026-06-16; the opt-out ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true "will only work until we upgrade the runner and remove Node20 on September 23rd, 2026". What the changelog does not state is whether an action that declares runs.using: node20 errors after that date; today such actions run on the forced Node 24 and pass. Either way every workflow here depends on a fallback GitHub calls temporary.

Measured across this repository's .github/**/*.yml at origin/master: 55 uses: references in 10 workflow files point at a major whose action.yml declares node20 (checked per action via the GitHub API at the pinned ref), and every one of those actions has a newer major that declares node24. 4 further files also need the bump but are modified by open PRs and are deferred to avoid conflicts (listed in the fix PR).
