Poetry 1.x (including the `poetry` version pinned in the generated publish workflow) ignores the `[project]` table, so since 5.32.0 packages built with it were published to PyPI without any license metadata. ## 5.33.1 **`(fix):`** Annotate generated WebSocket `__iter__` / `__aiter__` methods with `typing.Iterator[Response]` / `typing.AsyncIterator[Response]` so type checkers infer iterated messages as the response union (matching `recv()`) instead of `bytes | `.
