4.48.1
(fix): Fix WireMock stub generation for streaming endpoints. When an endpoint has both streaming
and non-streaming variants (via x-fern-streaming with stream-condition), the generated
WireMock stubs now include request body matching criteria to differentiate between them.
SSE stubs match on stream: true in the request body and have higher priority, ensuring
wire tests correctly route streaming requests to the SSE stub.
4.47.1
(chore): Update Dockerfile to use the latest generator-cli with improve reference.md generation.
4.47.0
(feat): Add X-Fern-Runtime (e.g. python/3.12.7) and X-Fern-Platform (e.g. darwin/25.2.0) telemetry headers to all requests for better runtime/platform observability.
4.46.14
(fix): Fix Python wire test generation/runtime robustness for missing examples, OMIT handling, client setup, and multipart file uploads.
4.46.13
(fix): Fixes Python SDK import generation to avoid invalid ._ module segments by deriving type paths from canonical declarations.
4.46.12
(fix): Support bytes as a response type for websocket channel methods.
4.46.11
(fix): Wire test generator now skips undefined example values and injects X-Test-Id in a constructor-compatible way via headers or httpx_client.
4.46.10
(fix): Fix wire test generation to use endpoint ID for lookup instead of path matching.
This fixes a bug where wire tests would call the wrong client methods when multiple
namespaces have endpoints with the same HTTP method and path pattern (e.g., POST /v2/Services).
4.46.9
(fix): Fix wire test generation to filter out nop values when generating method arguments.
This prevents invalid Python syntax like param= without a value when an example
contains an invalid enum value or undefined property.
4.46.8
(fix): Bump version to remove rc from version tag.
4.46.7-rc3
(fix): Fix wire test generation for streaming endpoints. Streaming methods return lazy iterators
(Iterator[bytes] or AsyncIterator[bytes]) that don’t execute the HTTP request until iterated.
Wire tests now wrap streaming endpoint calls in ‘for _ in …: pass’ loops to ensure the
HTTP request is actually made. This applies to streaming, streamParameter, and fileDownload
response types.
4.46.7-rc2
(fix): Fixed Python SDK generation to use native Pydantic field aliases and improved core parsing so wire-key and nested/union validation works correctly across Pydantic v1/v2.
4.46.7-rc1
(chore): Update Dockerfile to use the latest generator-cli with improve reference.md generation.
4.46.7-rc0
(chore): Skip installation of generator-cli in Python SDK generator as it is already installed in the base image.
4.46.6
(fix): Support custom x-fern-sdk-method-name on AsyncAPI operations.
4.48.0
(feat): Add opt-in pydantic_config.positional_single_property_constructors to allow Wrapper("value")
for single-required-field models (excluding discriminator literals). Note: can break if the model
later adds required fields; kwargs are more stable.
4.46.5
(chore): Update to support IR version 62.6.0 with new WebSocketMessage.methodName field,
webhook response descriptions, and OpenAPI explode parameter support.
4.46.4-rc2
(chore): Add sdkVersion as a top-level field in the generated metadata.json file.
4.46.4-rc0
(fix): Fix wire test generation to use config.client.exported_class_name for the client class name
instead of deriving it from the organization and workspace names. This ensures wire tests
import and instantiate the correct client class when a custom exported class name is configured.
