Line 130: The Node version should be updated to 24.13.0.

In this Dockerfile, I noticed that multiple Python and Node versions are installed to maintain backward compatibility.

Currently, some of the latest bench images have trouble running Frappe v15. We might want to address this to ensure v15 support.

My suggestion would be to drop v14 compatibility and add v15 instead. We could also rename the Python/Node version arguments to something more generic (e.g., PYTHON_VERSION_PREV / NODE_VERSION_PREV) rather than referencing a specific version.

You missed to update frappe branch in the custom dockerfile.

Just noticed today is the official EOL of version-14. So dropping compatibility should be fine in my opinion.
