 - Fixed: When using the Echo middleware the invoice response status code was 200 OK instead of 402 Payment Required (issue [#30](https://github.com/philippgille/ln-paywall/issues/30))
 - Fixed: When using the Echo middleware error responses (including the invoice) were wrapped in JSON instead of just text (issue [#30](https://github.com/philippgille/ln-paywall/issues/30))
+- Fixed: GoDoc for `storage.NewBoltClient(...)` contained usage suggestions that would lead to the possibility of clients cheating with reusing preimages
