v2.17.0

Compatibility Notes

• [orchestration, prompt-registry] LlamaGuard38B and LlamaGuard38BFilterConfig are now marked as deprecated and will be removed on 2027-09-20.
  Migrate usages before that date.

New Features

• [context-registry] Add tabular context registry package.
• [core] Add gemini-3.8-flash to the model types.
• [core] Add gpt-6-astra, gpt-6-luna, gpt-6.1-sol, gemini-3.6-flash, and nvidia--llama-nemotron-embed-1b to the model types.
• [langchain] Add reasoning content support to the Orchestration LangChain client.
  Reasoning blocks from model responses are surfaced in AIMessage.additional_kwargs.reasoning_content(preserving the signature for encrypted thinking), for both non-streaming and streaming responses.
  On subsequent turns, reasoning is forwarded back to the Orchestration service in reasoning_content from additional_kwargs.reasoning_content.
  Reasoning placed directly in message content is treated as output only and is not forwarded.
• [orchestration] Update generated client to latest spec (rel-1.13.2).
  Add optional provider_specific_fields property to LlmChoice and LlmChoiceStreaming response types.
• [orchestration] Update the generated client to spec v1.23.
  Adds the IBM Granite Guardian 4.1 content filter.
  Adds input filter target selectors.
  Adds the drop_unsupported_params option on LLMModelDetails.
• [prompt-registry] Update generated client to latest spec.
  Add deleteOrchestrationConfigsByScenario, deleteOrchestrationConfigHistory, deletePromptTemplatesByScenario, and deletePromptTemplateHistory API functions.
• [tabular-orchestration] Add experimental Tabular AI Orchestration package with TabularOrchestrationClient for predictions with Tabular Foundation Models.

Fixed Issues

• [langchain] Additional additional_kwargs properties (including tool_calls, intermediate_results, and reasoning_content) are now correctly placed on the AIMessage instead of the generation object.
• [langchain] Avoid retrying irrecoverable orchestration request and unsupported-model errors.
• [orchestration] Preserve prompt_tokens_details and completion_tokens_details in streamed token usage to fix missing cache and reasoning token details in OrchestrationStreamResponse.getTokenUsage() and getIntermediateResults().
• [orchestration] Fix missing prompt template or messages not being detected when no prompt is configured.
