 ### Changed
 
 - operator-rs: 0.25.0 -> 0.27.1 ([#212]).
+- Shortened the registration socket path for Microk8s compatibility ([#231]).
+  - After upgrading you will need to
+    `rmdir /var/lib/kubelet/plugins_registry/secrets.stackable.tech-reg.sock` manually.
+    This applies to *all* users, not just Microk8s.
