For the complete documentation index, see https://buildwithfern.com/learn/llms.txt. ## 1.42.0 **`(feat):`** Add streaming reconnect options on every Go SDK request: `option.WithMaxStreamReconnectAttempts(uint)`, `option.WithoutStreamReconnection()`, and `option.WithoutRetries()`. For SSE endpoints whose Fern definition sets `response-stream.resumable: true` (or whose OpenAPI sets `x-fern-streaming.resumable: true`), the generated streaming methods now reconnect transparently on mid-stream connection drops using SSE `Last-Event-ID` semantics, honoring server-sent `retry:` directives and capped by `MaxStreamReconnectAttempts` (default 5). No behavior change for endpoints that do not opt into `resumable: true`. The new option constructors are emitted unconditionally and have no effect on those endpoints.
