Feature enhancement details
To ensure the continued smooth running of the site's CI systems, all used github actions that currently run on node 20 should be updated to versions which run on node 24.
Why?
As per this notice from github blog,
"Node20 will reach end-of-life (EOL) in April of 2026. As a result we have started the deprecation process of Node20 for GitHub Actions."
More info:
For example, when the test job runs (example) the following warning is issued, in the "complete job" step:
Warning: Node.js 20 actions are deprecated. The following actions are running on Node.js 20 and may not work as expected: actions/checkout@v4, actions/setup-node@v4, actions/upload-artifact@v4. Actions will be forced to run with Node.js 24 by default starting June 2nd, 2026. Please check if updated versions of these actions are available that support Node.js 24. To opt into Node.js 24 now, set the FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true environment variable on the runner or in your workflow file.
Testing
Properly resolving this issue will be 2% code change and 98% doing thorough testing of the affected CI flows.
