+title: Release failure for {{ ref }}
+---
+
+Pipeline for release {{ ref }} failed. Please investigate.
+
+If the pipeline has failed before pushing to crates.io, delete the release tag
+and fix the release as necessary, retagging after complete. If the pipeline has
+failed after pushing to crates.io, create a new tag incrementing the version.
