0.64.37

(fix): Remove default docs for well known types in gRPC. Add support for field-level docs.

0.64.36

(fix): Change grpc converters to use the fully qualified name with package prefix for all conversions. Build support for well-known types.

0.64.35

(fix): Upgrade fdr and fdr-cjs dependencies to support grpc endpoints in convertIrToFdrApi.

0.64.34

(fix): Add global headers in endpoint example generation.

0.64.33

(feat): GA release with support for protobuf generation

0.64.32-rc1

(feat): Use ‘fern protoc-gen-fern’ in buf shell proxy instead of local cli build.

0.64.32-rc0

(feat): Reintroduce buf command/dependency.

0.64.31

(fix): Revert dependency on bufbuild package.

0.64.28

(feat): Support the x-displayName extension on the tag definition in OpenAPI. This allows OpenAPI specifications to define custom display names for tags that will be used in generated documentation.

0.64.26

(fix): Fixes the OpenAPI parser to correctly include query parameters in Content-Type: application/octet-stream requests.

0.64.25

(feat): Remove all org-specific legacy preview pins.

0.64.24

(feat): Added Server-Sent Events (SSE) support to Java stream implementation. The Java SDK generator now supports SSE streaming alongside existing JSON streaming, enabling real-time incremental responses for chat applications and live data feeds.

0.64.25

(fix): When a part in a multipart form request has Content-Type: application/json in OpenAPI or Fern Definition, interpret it as style: json.

0.64.23

(fix): Global headers are now used to create endpoint examples. When building endpoint examples, global headers are automatically included in the headers section of each example. This ensures that all endpoints have consistent header examples that match the global header configuration.

0.64.22

(feat): Make proto file target field optional in generators.yml

0.64.21

(feat): Introduce x-fern-discriminated extension to configure oneOf union behavior in OpenAPI specs.

1
# Example usage in OpenAPI schema
2
oneOf:
3
  - $ref: '#/components/schemas/Circle'
4
  - $ref: '#/components/schemas/Square'
5
x-fern-discriminated: false  # Treat as undiscriminated union

When x-fern-discriminated is set to false, the oneOf will be treated as an undiscriminated union instead of a discriminated union.

0.64.20

(fix): Remove ‘fern-check’ error for global header examples included with ‘x-fern-examples’

0.64.19

(fix): Pin Windows to legacy preview mode.

0.64.18

0.64.15

(fix): Fixed ExampleTypeFactory to ignore generating parameters in example when that parameter is both optional and deprecated

0.64.14

(fix): Separate nullable and optional property handling in IR conversion.

0.64.13

(fix): Respect additional properties in docs example generation by preserving them in generated examples instead of stripping unknown properties.
