## 5.15.0

**`(feat):`** Support `resumable` flag in SSE streaming endpoints. When an endpoint has
`x-fern-streaming.resumable: true`, the generated SDK now passes `resumable=True`
to `EventSource`, plumbing the flag through to the runtime for use by
reconnection logic. Adds `stream_reconnection_enabled` and
`max_stream_reconnection_attempts` request options for runtime control of
reconnection behavior.
