description: "Workflow-dispatch inputs in the github_actions action now use safe {{ variable }} templating, with raw Jinja2 deprecated."
---

The inputs you pass to a dispatched GitHub Actions workflow now support Mergify's simple, safe `{{ variable }}` interpolation — the same allowlisted templating rolling out across comment, review, and copy/backport message fields. Your existing `{{ }}` inputs keep working unchanged; raw Jinja2 templating in these inputs is now deprecated and will be removed in a future release.
