Changelog

April 10, 2026
April 10, 2026

5.4.0-rc.0

(feat): Upgrade to IR v66 which compresses the IR Name type, reducing IR size and increasing performance.

5.3.11

(fix): Fix duplicate keyword arguments in generated code for discriminated union request bodies with stream condition properties. When a union variant inherits the stream condition field from a base schema via extends, the property was emitted twice — once from the union’s base properties and once from the variant’s extended properties — causing SyntaxError in generated Python code.

(fix): Escape triple quotes in docstrings to prevent premature docstring termination when OpenAPI descriptions contain Python code examples with triple-quoted strings.

(fix): Fix mypy call-overload errors in exported client wrapper by mirroring the base client’s @overload signatures and using **kwargs pass-through, instead of suppressing the error with a type: ignore comment.

5.3.10

(chore): Bump generator-cli to 0.9.6 which upgrades @fern-api/replay to 0.10.3.

5.3.9

(chore): Bump generator-cli to 0.9.5 which upgrades @fern-api/replay to 0.10.2.
