- All versions, including delete-markers should be deleted before deleting a bucket.
- **Versioning feature is only available in erasure coded and distributed erasure coded setups**.

## How to configure versioning on a bucket

Each bucket created has a versioning configuration associated with it. By default bucket is unversioned as shown below

```

	// On form submission, the last redirect response contains the auth
	// code, which we now have in `lastReq`. Exchange it for a JWT id_token.
	q := lastReq.URL.Query()
	// fmt.Printf("lastReq.URL: %#v q: %#v\n", lastReq.URL, q)
	code := q.Get("code")
	oauth2Token, err := oauth2Config.Exchange(ctx, code)
	if err != nil {
		return "", fmt.Errorf("unable to exchange code for id token: %v", err)
	}
