-- matrix: Send the display name instead of the user name (matrix) (#1282)  
-  Matrix now sends the displayname if set instead of the username. If you want to keep the username, add  `UseUsername=true` to your matrix config. <https://github.com/42wim/matterbridge/wiki/Settings#useusername-1>

-  Because of issues with ratelimiting of webhook editing, this feature is now disabled. If you have multiple discord channels you bridge, you'll need to add a `webhookURL` to the `[gateway.inout.options]`. See <https://github.com/42wim/matterbridge/blob/master/matterbridge.toml.sample#L1864-L1870> for an example.
