Changelog

4.61.0

(feat): Add support for DATE_TIME_RFC_2822 primitive type. Fields with format: date-time-rfc-2822 in OpenAPI specs now generate as Rfc2822DateTime (a datetime.datetime subclass) that parses RFC 2822 date strings (e.g., “Wed, 02 Oct 2002 13:00:00 GMT”) using Python’s email.utils.parsedate_to_datetime. Compatible with both Pydantic V1 (__get_validators__) and V2 (__get_pydantic_core_schema__), passing mypy strict type checking.

(fix): Fix code snippet generation for RFC 2822 datetime fields to use email.utils.parsedate_to_datetime() with RFC 2822 format strings instead of datetime.fromisoformat() with ISO 8601 format.

4.60.2

(fix): Fix explode: false query parameter serialization for array types. When an OpenAPI spec sets explode: false on an array query parameter, the generated SDK now serializes values as comma-separated strings (e.g. tags=A,B,C) instead of repeated keys (e.g. tags=A&tags=B&tags=C). This applies to both regular and streaming endpoints.

4.60.1

(chore): Use generator-cli JS API directly instead of subprocess spawning. Remove generator-cli from Docker image since it is now bundled via esbuild.
