Dec 1, 2025December 2025 focused on delivering business-value features, reliability fixes, and performance improvements across BerriAI/litellm. Highlights include cross-provider header fidelity for LLM providers, expanded JWT auth routes to support broader workflows, and Ragflow-based vector store integration enabling efficient search and retrieval. Numerous stability bugs were fixed (Gemini 3 last chunk, import errors, malformed requests), and cost visibility improvements were added with passthrough tracking for VEO. Cursor BYOK and litellm proxy enhancements strengthen secure, scalable deployments. Additional API improvements (output_tokens_details mapping) and header forwarding enhancements reduce integration friction. Widespread CI improvements, tests, and code-quality fixes improved overall maintainability and reliability, supporting faster delivery cycles and better customer value.
