## 2.54.0

**`(feat):`** Support `x-fern-server` on AsyncAPI channels for multi-URL environments.
When a channel specifies a `baseUrl` (via `x-fern-server`) that maps to a
multi-URL environment in the IR, the C# generator now automatically derives
websocket environments from the IR's environment definitions. This eliminates
the need for the `temporary-websocket-environments` workaround in
`generators.yml`.
