  • Documentation site header updated — logo replaces text title
  • Installation guide restructured for clarity

[0.1.1] — 2026-04-04

Added

  • CPU / GPU install separation — dedicated [cpu] and [gpu] meta-extras for clean one-command installs
  • faiss-gpu extra (faiss-gpu>=1.7) as a distinct option from faiss-cpu
  • Granular torch-based extras — embeddings-cpu, embeddings-gpu, latex-ocr-cpu, latex-ocr-gpu for fine-grained dependency control

Fixed

  • Package metadata: license field updated to SPDX expression format per PEP 639
  • Documentation site build reliability improvements

Changed

  • [gpu] is now the recommended default install — one command, works on both GPU and CPU machines
  • [cpu] documented as the advanced path for size-constrained environments (Docker, edge, CI)
  • [all] now resolves to [cpu] as a safe, dependency-minimal default

[0.1.0] — 2026-04-04

🎉 Initial Public Release

LongParser is the open-source document intelligence engine built by ENDEVSOLS for production RAG pipelines.

Added

  • 5-stage extraction pipeline — Extract → Validate → HITL Review → Chunk → Embed → Index
  • Multi-format extraction — PDF, DOCX, PPTX, XLSX, CSV via Docling
  • HybridChunker — token-aware, heading-hierarchy-aware, table-aware chunking
  • Human-in-the-Loop (HITL) review — approve / edit / reject blocks and chunks via LangGraph interrupt() before embedding
  • 3-layer memory chat — short-term turns + rolling summary + long-term facts, powered by LCEL chains
  • Multi-provider LLM support — OpenAI (gpt-5.3), Gemini (gemini-2.5), Groq (llama-3.3-70b-versatile), OpenRouter
  • Multi-backend vector stores — Chroma, FAISS, Qdrant
  • Async-first REST API — FastAPI + Motor (MongoDB) + ARQ (Redis job queue)
  • LongParserRetriever — drop-in LangChain BaseRetriever adapter
  • LongParserLoader — LangChain document loader integration
  • LongParserReader — LlamaIndex BaseReader integration
  • LongParserCallbackHandler — observability callbacks for LangChain chains
  • Built-in citation validation — chunk IDs verified against retrieved set before any answer is returned
  • Privacy-first — all processing runs locally; no data leaves your infrastructure
  • py.typed marker — full PEP 561 typing support
  • Unit test suite — test_schemas.py (22 passing), test_llm_chain.py, test_chat_utils.py
  • GitHub Actions CI — lint (ruff), tests across Python 3.10 / 3.11 / 3.12, coverage reporting
  • GitHub Actions publish — PyPI trusted publishing triggered on GitHub releases
  • pyproject.toml with server, langchain, llamaindex, embeddings, chroma, faiss, qdrant optional extras
  • Dockerfile and docker-compose.yml for one-command local deployment
  • CONTRIBUTING.md, SECURITY.md, .env.example — full OSS scaffolding
