Pull request overview

Major-version GA release update for azure-search-documents, regenerating from the Search data-plane TypeSpec and aligning the Python surface area with the 2026-04-01 API (including removal of preview-only types/features not promoted to GA).

Changes:

• Regenerated SDK and bumped package version to 12.0.0 with default API version 2026-04-01.
• Removed preview-only models/enums/parameters (notably several search/debug/hybrid/vector threshold and SharePoint-related types) and updated tests accordingly.
• Updated model serialization/deserialization helpers and streaming response handling (added decompress option gating iter_bytes() vs iter_raw()).

• decompress is popped from kwargs before calling pipeline.run, so the decode/decompression policy will never see a caller-provided decompress=False. This can lead to inconsistent behavior (e.g., response may still be decompressed while iter_raw() is returned). Prefer reading decompress with kwargs.get(...) (or passing it through) so the pipeline and the streaming iterator stay consistent.

        _decompress = kwargs.pop("decompress", True)
        _stream = kwargs.pop("stream", False)
        pipeline_response: PipelineResponse = self._client._pipeline.run(  # pylint: disable=protected-access

• decompress is popped from kwargs before calling pipeline.run, so a caller-provided decompress=False won't reach the pipeline decode/decompression policy. This can make iter_raw()/iter_bytes() selection inconsistent with what actually happened in the pipeline. Prefer kwargs.get("decompress", True) (without popping) or otherwise ensure the flag is passed through to pipeline.run.

• decompress is popped from kwargs before calling pipeline.run, which prevents a caller-provided decompress=False from reaching the pipeline decode/decompression policy. This can result in returning iter_raw() even though the response was already decompressed (or vice versa). Prefer reading decompress without removing it from kwargs, or pass it through explicitly to pipeline.run.

        _decompress = kwargs.pop("decompress", True)
        _stream = kwargs.pop("stream", False)
        pipeline_response: PipelineResponse = await self._client._pipeline.run(  # type: ignore # pylint: disable=protected-access
            _request, stream=_stream, **kwargs
        )

• decompress is popped from kwargs before calling pipeline.run, so a caller-provided decompress=False will never reach the pipeline decode/decompression policy. That can make the returned streaming iterator (iter_bytes() vs iter_raw()) inconsistent with how the pipeline handled the response. Prefer kwargs.get("decompress", True) (no pop) and pass the flag through to pipeline.run.

• The generated search request builders no longer accept/serialize the document-security headers (x-ms-query-source-authorization, x-ms-enable-elevated-read). As a result, passing the existing x_ms_query_source_authorization / x_ms_enable_elevated_read kwargs (used in current tests and mentioned in earlier changelog entries) will have no effect on outgoing requests. If these headers are still supported in the GA API, please re-add plumbing via kwargs->headers or the headers kwarg; otherwise, the docs/tests/changelog should be updated to reflect their removal.
