 Both SDKs default to `https://api.saturday.fit` and accept a base URL override (`base_url` in Python, `baseUrl` in TypeScript) for sandbox work.
 
-The SDKs cover the calculation methods shown here. For activity prescriptions and AI streaming, call the HTTP endpoints directly.
+SDK 0.6.0 aligns prescription, batch, import, pagination, and athlete-settings types with the API while preserving raw response objects. Activity calculations return a tiered envelope; stored-prescription reads return `{prescription, safety}`, not the flat nutrition response above. Safety warnings may be `null`. Existing typed callers should read the migration notes in the [TypeScript SDK](https://github.com/SaturdayInc/saturday-node#readme) or [Python SDK](https://github.com/SaturdayInc/saturday-python#readme).

+AI coaching remains [feature-gated](/guides/feature-gates). With `ai_coach` access, use `ai.createConversationStream` / `ai.sendMessageStream` in TypeScript, or the async context-managed `ai.create_conversation_stream` / `ai.send_message_stream` methods in Python. Consume all events, including safety warnings and errors. These writes are never automatically replayed, and a partial stream is not a complete answer. Legacy AI JSON-write methods fail locally with migration guidance; conversation metadata/history reads remain JSON. The SDK READMEs include executable stream examples and cancellation guidance.
