# Upgrading to v1.53.0
## Dropping support for `webclient` listeners and non-HTTP(S) `web_client_location`
Per the deprecation notice in Synapse v1.51.0, listeners of type `webclient`
are no longer supported and configuring them is a now a configuration error.
Configuring a non-HTTP(S) `web_client_location` configuration is is now a
configuration error. Since the `webclient` listener is no longer supported, this
setting only applies to the root path `/` of Synapse's web server and no longer
the `/_matrix/client/` path.
# Upgrading to v1.51.0
## Deprecation of `webclient` listeners and non-HTTP(S) `web_client_location`
