+  * lvm plugin: fix hanging on the storage lock when doing a snapshot rollback
+    through the CLI.
+
+  * fix #6900: accept all API tokens that are valid for Proxmox Backup Server,

+  * api: OCI image download improvements:
+    - use temporary file and only rename to real one if pulling the image
+      finished successfully.

+    - improve reference regex to allow more safe characters, like e.g. '-',
+      in the image name.
+    - allow one to override the target filename for the image.
