5.11.1

[5.11.1] - 2020-07-07

Changed:

• Updated the README to have updated usage guidance and to fix outdated links.

Fixed:

• When proxying events, events that were received from JavaScript browser clients via the special image-loading endpoint (used if the browser does not support CORS) could be lost.
• When Prometheus metrics are enabled, the /metrics endpoint that Relay provides for the Prometheus agent to query was being added globally using http.Handle; that meant that if an application used Relay as a library, and used http.ListenAndServe with the default handler, it would have a /metrics endpoint on its own port. This has been fixed so the endpoint is only defined on the Prometheus exporter's port.
• Stream reconnections now use a backoff delay with jitter, instead of a fixed delay.
