> Microsoft released Semantic Kernel python-1.47.0 on November 5, 2026. The release notes say it requires Python 3.11 or later (3.10 support removed; tested through 3.14), batches Google AI embedding requests to the 100-input limit, respects optional MCP prompt arguments, propagates MCP init failures, and wires ChatHistoryReducer into ChatCompletionAgent.

## What changed

- Compatibility break: the release notes state python-1.47.0 requires Python 3.11 or later, removes Python 3.10 support, and lists supported and tested versions as 3.11 through 3.14.
- Google AI embeddings: Python now batches Google AI embedding requests to the 100-input limit, and Google AI completions count Gemini thinking tokens in usage.
- MCP: optional MCP prompt arguments are respected, and MCP initialization failures are propagated instead of being swallowed.
- Agents: ChatHistoryReducer is wired into ChatCompletionAgent invocation, empty tool results are kept through the prompt round trip, and non-adjacent tool pairs are preserved during history truncation.
- Connector fixes: Redis vector search is restored after the redisvl>=0.5 API change (including include_vectors=False), Mistral AI chat completion no longer crashes on unknown finish reasons such as model_length, and Mistral AI seed setting is accepted by the SDK.
- Also listed: OpenAPI allowlist path-case and prefix-match fixes, SQL Server and Oracle collection query fixes, NVIDIA nvext via extra_body, and consolidated Python dependency updates for the 1.47.0 cut.

## What we have not verified

- We did not install or run semantic-kernel 1.47.0, or re-test MCP, Redis, Mistral, Google AI, SQL Server or Oracle paths.
- The .NET items in the same release notes (including a labelled BREAKING file-access change) are out of scope for this Python package brief.
- We did not verify the consolidated dependency pin set beyond what the release notes state.
