v0.3.0.3

Release date: 2026.9.15

## Highlights

This release expands UltraRAG’s retrieval and generation options with a Qdrant vector search backend, a dedicated LiteLLM generation backend, and jieba support for Chinese tokenization.

We improve correctness and reliability by keeping legacy knowledge bases private by default, fixing query extraction in R1-Searcher, correcting evaluation scores for article-only answers such as the multiple-choice option “A”, and refining the AgentCPM-Report pipeline.

We also unify the CUDA 12.9 dependency environment, improve FAISS loading on Windows, and refresh backend and frontend dependencies.
