+## v0.68.0 - 2022-06-21

+This release fixes a bug in the garbage collector.
+If you are using cloud storage that is not S3 and have configured a garbage collection policy for retention, you will need to reconfigure it.  (Note that the garbage collector itself does not yet run on such storage!)
+There are no changes if you are using S3.
