## Body
Google Gen AI SDK v2.33.0 introduces several new features and bug fixes. Key features include adding store to GenerateContentConfig (restricted to the Gemini Developer API) and labels to LiveConnectConfig . Multimodal responses in tool calls are expanded by including AudioContent , DocumentContent , and VideoContent in FunctionResultSubContent . The release adds support for Python 3.15 and client-side configuration for httpx2 via GOOGLE GENAI HTTP CLIENT . Bug fixes address skipping mTLS URL rewriting for multi-regional .rep.googleapis.com endpoints, honoring GOOGLE API USE MTLS ENDPOINT in Google Auth sessions, respecting explicit zero delay fields in HttpRetryOptions , and properly honoring HttpRetryOptions on aiohttp connection errors during async requests. Documentation was also updated regarding unenforced JSON Schema keywords on Interactions schema fields.

## Recommended actions
- Upgrade google-genai SDK to v2.33.0 if using new configuration fields or Python 3.15.
- Verify async retry behavior if relying on HttpRetryOptions with aiohttp connection errors or zero-delay configurations.
- Adopt AudioContent, DocumentContent, or VideoContent in FunctionResultSubContent if returning multimodal outputs from tool calls.
