depup 0.2.0

Dependency Upgrade Advisor: scan and safely upgrade Python project dependencies.

depup — Dependency Upgrade Advisor

Depup is a modern Python CLI tool that helps developers keep their project dependencies up-to-date, safe, and maintainable. It automatically:

• Scans for declared dependencies
• Detects updates on PyPI
• Classifies semantic versioning impact (patch/minor/major)
• Prepares upgrade paths
• (Future) Provides AI-assisted upgrade analysis and code fixes

This tool is built for modern development workflows and future integration with AI agents (Cursor, Windsurf, Continue) via MCP.

🔖 Version Management

We use bump2version to automate versioning:

bump2version patch  # 0.1.1 → 0.1.2
bump2version minor  # 0.1.1 → 0.2.0
bump2version major  # 0.1.1 → 1.0.0
