+features:
+  - |
+    Adds "manila_cephfs_filesystem_name" variable to support multi-fs
+    Ceph Pacific+ deloyments.
+fixes:
+  - |
+    Removes "fix_cephfs_owner.yaml" which related to pre-wallaby Manila's
+    use of subfolders. Post-wallaby Manila now uses cephfs volumes instead,
+    as such this file is no longer required.

+  - |
+    Removes use of "cephfs_enable_snapshots" in Manila config as this
+    option was removed from Manila in the Wallaby release.
