+Requirement for X-Forwarded-Proto header
+----------------------------------------
+
+When using Synapse with a reverse proxy (in particular, when using the
+`x_forwarded` option on an HTTP listener), Synapse now expects to receive an
+`X-Forwarded-Proto` header on incoming HTTP requests. If it is not set, Synapse
+will log a warning on each received request.
+
+To avoid the warning, administrators using a reverse proxy should ensure that
+the reverse proxy sets `X-Forwarded-Proto` header to `https` or `http` to
+indicate the protocol used by the client. See the [reverse proxy
+documentation](docs/reverse_proxy.md), where the example configurations have
+been updated to show how to set this header.
+
+(Users of `Caddy <https://caddyserver.com/>`_ are unaffected, since we believe it
+sets `X-Forwarded-Proto` by default.)
