+k6registry `v0.1.23` is here 🎉!
+
+This is an internal maintenance release.
+
+**Fix cache saving issue**
+
+The GitHub workflow is running with user id `1001` and group id `127`. The k6registry docker container runs with the default user id in debian.  As a consequence, the cache directory created under XDG_CACHE_HOME fails to save.
+
+The solution is to use the same user id and group id as the GitHub workflow in the k6registry docker container (user id: `1001`, group id: `127`).
