 ## 4.68.0
 **`(feat):`** Add support for `x-fern-display-name` on AsyncAPI operations. This allows setting friendly display names on AsyncAPI v2 publish/subscribe operations and v3 operations, which is useful when operation keys need to be normalized (e.g. for versioned endpoints) but you still want readable names in docs.
