4.45.9
(fix): Fix empty query params stripping existing URL query strings. When params and
additional_query_parameters are both empty, httpx now receives params=None instead
of params=[], preserving any query parameters already present in the URL (e.g.,
pagination cursors like ?after=123).
4.45.8
(fix): Ensures the root client always exposes a headers parameter and forwards it to the underlying ClientWrapper.
4.45.7
(fix): Fix client wrapper instantiation to use the correct bearer token parameter name, preventing incorrect token= references when custom auth parameter names are configured.
