- **CreateBucket:** Garage does not yet accept creating buckets or giving access using API calls, it has to be done using the CLI tools. CreateBucket will return a 200 if the bucket exists and user has write access, and a 403 Forbidden in all other cases.
- **DeleteBucket:** Garage does not yet accept deleting buckets using API calls, it has to be done using the CLI tools. This request will return a 403 Forbidden.
- **GetBucketVersioning:** Stub implementation (Garage does not yet support versionning so this always returns
"versionning not enabled").
- **ListObjects:** Implemented, but there isn't a very good specification of what `encoding-type=url` covers so there might be some encoding bugs. In our implementation the url-encoded fields are in the same in ListObjects as they are in ListObjectsV2.
