# Release Notes - LangChain v1 Migration

## Breaking Changes

**Python 3.10+ now required** - LangChain v1 drops Python 3.9 support. Please upgrade to Python 3.10 or higher (Python 3.12 recommended).

## Updates

### LangChain v1 Compatibility
Upgraded to LangChain v1.0+ with updated import paths across the codebase:
- `langchain.prompts` → `langchain_core.prompts`
- `langchain.text_splitter` → `langchain_text_splitters`
- `langchain.retrievers` → `langchain_classic.retrievers`

### Package Versions
- `langchain>=1.0.0`

- `langchain-community>=0.4.0`
- `langchain-classic>=1.0.0` (new)

### Simplified Dependencies
Reduced `requirements.txt` from 134 to 63 lines by removing transitive dependencies - now only lists packages directly used by the project.

# Install with Python 3.10+
