5.49.0
(feat): Add support for x-fern-subtitle OpenAPI extension on endpoints. When set,
the subtitle is rendered below the endpoint title in the docs UI.
5.48.0
(feat): Add a --local flag to fern docs md generate that runs the library
documentation parsers locally in Docker instead of using Fern’s servers.
Local generation requires no authentication and operates on path inputs
(local source); git inputs continue to be generated remotely.
