Changelog

March 5, 2026
March 5, 2026

4.62.0

(feat): Add README.md and reference.md generation to the python-v2 SDK generator. The v2 generator now produces README documentation with feature snippets (installation, usage, timeouts, custom client, exception handling, raw responses, websockets, custom sections) and endpoint reference documentation.

(chore): Format AST output with trailing commas in multiline function calls and inline list/dict formatting for improved code readability.

4.61.5

(fix): Fix WebSocket client generation to respect pydantic_config.skip_validation: true. Previously, socket clients always used parse_obj_as (full Pydantic validation) regardless of the skip_validation flag. They now correctly use construct_type (no validation) when the flag is enabled, matching the behavior of HTTP clients.
