v5.11.0 release notes

• Authentication
  • Added auth.SchemeAuthenticator interface that authenticators can implement to indicate the scheme they are using. On authentication failure, the auth middleware adds the WWW-Authenticate header to the response if the authenticator implements auth.SchemeAuthenticator.
  • Added auth.MiddlewareWithRealm to provide custom realm description for the WWW-Authenticate header.
• Added an explicit error message when server.RegisterRoutes is called more than once.
• Static file serving: fixed an issue on Windows which resulted in 404 errors if the filesystem was embedded and the requested path contained slashes.
