- Add OAuth M2M (Machine-to-Machine) authentication via DATABRICKS_CLIENT_ID and DATABRICKS_CLIENT_SECRET
- Add Databricks SDK auto-auth with automatic credential discovery
- Add sensitive data redaction for secure logging (tokens, API keys, secrets)
- Add custom user_agent parameter for partner attribution in Databricks telemetry
- Support user_agent in LiteLLM Proxy via config.yaml litellm_params
- Add 49 mocked unit tests for all new functionality
- Add 13 E2E tests for real-world validation (skipped in CI)
- Update documentation with new features and examples
The Responses API expects tool results to use input_text/input_image types,
not output_text. This fix ensures consistent list format for all tool results:
- String content → [{"type": "input_text", "text": "..."}]
- Image content → [{"type": "input_image", "image_url": "..."}]
This resolves the conflict between tests that expected different formats
and aligns with OpenAI's Responses API requirements.
Fixes the regression introduced in #18226.
- test_tool_message_output_is_string_not_list: verifies function_call_output.output is a string
- test_multiple_tool_calls_in_single_choice: verifies multiple tool calls are grouped in one choice
* fix: enforce team member budget check in common_checks
- Add missing team member budget validation in common_checks() function
- Checks team membership budget when team key is used
- Raises BudgetExceededError when team member spend exceeds max_budget_in_team
- Follows same pattern as other budget checks (team, user, end_user)
- Uses cached get_team_membership() for performance
- Fix AttributeError in lowest_tpm_rpm.py
- Add null check for model_info before accessing .get() method
- Prevents 'NoneType' object has no attribute 'get' error
- Add unit tests for team member budget enforcement
- Test budget exceeded scenario
- Test within budget scenario
- Test edge cases (no budget, no membership, personal keys)
- Tests run without requiring proxy server
Fixes failing test: test_users_in_team_budget
* fix: mock get_async_httpx_client in test_langsmith_key_based_logging
- Mock get_async_httpx_client to return a mock AsyncHTTPHandler instance
- Fixes test failure where mock_post was never called
- LangsmithLogger creates its own httpx client instance via get_async_httpx_client,
so we need to mock the factory function rather than the class method
- Use MagicMock for response.raise_for_status (sync method) instead of AsyncMock
* fix: resolve linting errors (PLR0915, F401)
- Remove unused imports (datetime, ServiceLoggerPayload) from arize_phoenix.py
- Extract health ping setup logic from RedisCache.__init__ to reduce statement count
- Extract team member budget check from common_checks to reduce statement count
* fix: resolve type errors in ChatCompletionToolCallChunk construction
- Cast type field to Literal['function'] to satisfy TypedDict requirements
- Ensure arguments field is explicitly str type to match TypedDict signature
- Fixes pyright errors for incompatible types in transformation.py
