An Nginx proxy has been configured as the entrypoint for Synapse. This is not
optional. This is done to counteract IP collection in Synapse itself. See more:

!!! You MUST undeploy your Synapse install before upgrading to this version !!!

This is because there have been a service rename in the recipe configuration:

* `app` -> `synapse`

This could break stuff in the recipe, so please report issues if you run into
anything!
