+### 6.x -> 7.x
+
+`v7` changes how the module references storage from using terraform's `count` to always creating a "defaultBucket" which can be overidden latter or but providing some initial bucket.
+
+We are considering this a major change because of the terraform `moved` block which migrates the resource. After moving to a `v7` applying an earlier version of the module may result in terraform deleting your bucket.
+
+removed the `create_bucket` var due to the above.
 ### Upgrading from 2.x -> 3.x
