* feat(models): add Azure GPT-5.4 mini and nano variants (#24045)

Add `azure/gpt-5.4-mini` and `azure/gpt-5.4-nano` to the model
database with official pricing from Azure OpenAI:

- GPT-5.4 mini: $0.75/M input, $0.075/M cached, $4.5/M output
- GPT-5.4 nano: $0.20/M input, $0.02/M cached, $1.25/M output

Both models support:
- 1.05M input / 128K output context window
- Chat, batch, and responses endpoints
- Function calling, tools, vision, reasoning
- Prompt caching with automatic tiered pricing

* Add new model pricing details for volcengine Doubao-Seed-2.0 series (#23871)

Add entries for volcengine Doubao-Seed-2.0 series

* fix(mcp): support refresh_token grant type in OAuth token endpoint (#23701)

* fix(mcp): support refresh_token grant type in OAuth token endpoint (#23700)

The .well-known/oauth-authorization-server metadata advertises
refresh_token as a supported grant type, but the token endpoint
rejected it with HTTP 400. This adds refresh_token grant support
so MCP clients can refresh expired tokens without re-authenticating.

* test(mcp): add tests for refresh_token grant type in OAuth token endpoint

* fix(mcp): move code_verifier guard into authorization_code branch

code_verifier is only relevant for authorization_code grants (PKCE).
Move it inside the else branch so it doesn't apply to refresh_token.

* fix(mcp): guard None client_secret and forward scope in token exchange

- Conditionally include client_secret in form data to prevent httpx
  from sending the literal string "None" (applies to both
  authorization_code and refresh_token branches)
- Forward optional scope parameter per RFC 6749 §6, allowing clients
  to request a subset of originally-granted scopes on refresh

* fix(mcp): validate code param in authorization_code grant

Guard against None code being form-encoded as literal string "None"
by httpx, symmetric with the existing refresh_token guard.

* docs: add incident report for guardrail logging secret exposure (#24059)

Add blog post documenting the guardrail logging path exposing internal
request data (e.g. Authorization headers) in spend logs and OTEL traces.
Fix available in LiteLLM 1.82.3+.

Made-with: Cursor

* [Fix] Datadog LLM Observability tags format (env, service, version missing) (#23673)

* tag fix

* greptile comment

* fix(ci): stabilize 6 failing CI jobs

1. mypy: remove duplicate type annotation for token_data in discoverable_endpoints.py
2. integrations tests: add parameterized to CI test deps
3. doc quality: document OTEL_IGNORE_CONTEXT_PROPAGATION env key
4. security: allowlist CVE-2026-2673, CVE-2026-3644, CVE-2026-4224 (no fix available)
5. proxy_store_model_in_db: fix missing x-litellm-call-id header on error responses
6. google tests: add --retries 3 for transient Vertex AI rate limits

* fix(streaming): handle RuntimeError during model_copy in streaming handler

The race condition occurs when model_copy(deep=True) tries to deepcopy
_hidden_params dict while it's being concurrently modified by logging
callbacks. Fall back to shallow copy if the deep copy fails.

* fix(cost): handle non-string traffic_type in cost calculator + add retries

1. Fix AttributeError in _map_traffic_type_to_service_tier when traffic_type
   is an integer (cast to str before calling .upper()). This was causing
   pass-through vertex spend logging to fail silently.
2. Add --retries to llm_translation_testing for flaky external API calls.
